    Opis:
    Genetic research allows not only for precise diagnosing of diseases, but also for selecting therapy and appropriate medicines, and for insight into future health condition. Genetic information obtained as a result of genetic research is related not only to patients, but to their relatives, too. In this context a threat arises of abuse, infringement of human rights and unauthorised access to genetic data. The audit of NIK was aimed, in the first place, to examine whether genetic research in Poland is conducted with due care for safety requirements, that is whether Polish legal regulations keep up with the development of modern technologies in medicine.

    The medicinal plants of Jordan are under threat due to several factors of habitat perturbation. Some of these factors include ruinous over-harvesting, climate change, competition and invasion. In this study, the authors employed a reliable method for micropropagation and assessment of antimicrobial activity of some important medicinal plants of Jordan. Seeds were surface sterilized and germinated on agar water media, and then shoots were cultured on Murashige and Skoog (MS) medium with the addition of 3% sucrose. In order to generate enough plant material, microshoots were transferred after fourteen days onto hormone free MS medium. Among all studied plants, it was found that the Achellia millefolium and Moring perigrina plants successfully multiplied in vitro containing different 6-benzyl amino purine (BA). For potential antimicrobial activity, the ex vitro (field leaf plants) and in vitro (plantlet) extracts were evaluated against some bacteria strains using ethanolic extracts. Both ex vitro and in vitro plants extracts showed the antimicrobial activity against the microorganism tested. The results from the study suggest that these two plants showed good antimicrobial activity against the different tested bacteria.

    Opis:
    Background. During the recent years, appropriate attention has been paid to the oxidative stress which damages the body’s cells, proteins, and DNA. Therefore, the need of antioxidants becomes a therapeutic and preventive priority. In addition, microbial infections also constitute a public health problem. Objective. To find efficient, reliable and safe alternatives sources to synthetic antioxidants, antibiotics and antifungals drugs. Materials and methods. Extract and essential oil of Psidium guajava were screened for their antioxidant and antimicrobial activities against gram positive bacteria (Enterococcus faecalis and Staphylococcus aureus), gram negative bacteria (Citrobacter freundii, Escherichia coli and Pseudomonas sp) and fungi (Candida albicans,Candida tropicalis and Cryptococcus neoformans), as well as to determine the functional groups of phytochemicals present in the essential oil by Fourier transform infrared spectroscopy (FTIR). Results. The results indicate that P. guajava leaves extract demonstrated very high antioxidant activity and P.guajava essential oil showed the highest polyphenols content. The antioxidant capacity showed a significant negative linear correlation to total polyphenolic content (TPC) with Pearson’s correlation coefficients. P. guajava essential oil shows high antibacterial and antifungal activity against all the studied bacteria and fungi.The FTIR analysis of P. guajava essential oil showed the presence of several functional groups (ethers, esters, ketones, terpenes, alkanes, aldehydes, aromatic hydrocarbons, alcohols, and phenols). The relationship between the chemical composition and antimicrobial activity of P.guajava essential oil suggests that the attribution of its antimicrobial activity to a particular compound or a synergistic effects between its different constituents remains difficult. Conclusions. The present study demonstrated that Psidium guajava is a valuable source of active compounds with anti- oxidant and antimicrobial activities. This finding suggests the new use of the fruits and the leaves extracts of this plant in the treatment of bacterial and fungal infections, as well as for the extraction of new antioxidants. Therefore, it is necessary to be carried out in another study to identify the active(s) compound(s) in P.guajava essential oil with respect to their mechanisms and synergistic actions.

    Opis:
    The current study was intended to evaluate abortifacient and antioxidant activity of Avicennia marina leaves extracts. Abortifacient activity was evaluated in rats, compared with standard drug (Mifepristone) and antioxidant activity was evaluated by using three free radicals (Superoxide, Hydroxyl and DPPH) compared with Ascorbic acid. The extracts were showed pre implantation loss, post implantation loss of implantations and decreased the survival ration of foetuses. Among all extracts hydroalcoholic extract showed better activity. The selected plant extracts showed concentration dependent percentage inhibition of free radicals. Among three extracts hydroalcoholic extract showed better activity with IC50 values on superoxide, hydroxyl and DPPH radicals were 203μg, 237μg and 143μg. From the results obtained during the study it the hydroalcoholic extract was used for the isolation of pure compounds, and isolated the different compounds (β-sitosterol, Lupeol and Betulinic acid).

    This article offers publication of seventeen miniature vessels discovered in Hellenistic strata of Athribis (modern Tell Atrib) during excavations carried out by Polish-Egyptian Mission in the 1980s/1990s. The vessels, made of clay, faience and bronze, are mostly imports from various areas within the Mediterranean, including Sicily and Lycia, and more rarely – local imitations of imported forms. Two vessels carry stamps with Greek inscriptions, indicating that they were containers for lykion, a medicine extracted from the plant of the same name, highly esteemed in antiquity. The vessels may be connected with a healing activity practised within the Hellenistic bath complex.

    Opis:
    Epimedium pinnatum (Berberidaceae family) is used as an aphrodisiac in traditional Chinese medicine (TCM). The aim of this study was to evaluate the antimicrobial and antioxidant activity of E. pinnatum extracts (ethanol, methanol and aqueous extracts). Total phenolic (TPC) and flavonoid contents (TFC) of each extract were assessed by spectrophotometric methods. It was exhibited that methanol extract had better antimicrobial activity than those of ethanolic extract or aqueous extract. The TPC and TFC of E. pinnatum extracts was higher in methanol extract (149 and 36.6 mg/g) than that of ethanolic extract (137.2 and 19.5 mg/g) and aqueous extract (86.2 and 8.4 mg/g). The methanol extract had lower IC50 value (200 µg/ml) than ethanolic (250 µg/ml) and aqueous extract (400 µg/ml). There was a positive correlation between TPC, TFC in E. pinnatum extract and their antioxidant and antimicrobial activity.
    W tradycyjnej medycynie chińskiej Epimedium pinnatum (rodzina Berberidaceae) używa się jako afrodyzjaku. Celem niniejszej pracy była ocena działania przeciwbakteryjnego i przeciwutleniającego wyciągów: etanolowego, metanolowego i wodnego z Epimedium pinnatum. Całkowita zawartość fenoli i całkowita zawartość flawonoidów w każdym z wyciągów została oznaczona metodami spektrofotometrycznymi. Wykazano, że wyciąg metanolowy miał lepsze działanie przeciwbakteryjne niż wyciąg etanolowy i wodny. Całkowita zawartość fenoli i całkowita zawartość flawonoidów była wyższa w wyciągu metanolowym (149 i 36,6 mg/g) niż etanolowym (137,2 i 19,5 mg/g) i wodnym (86,2 i 8,4 mg/g). Wyciąg metanolowy miał niższą wartość IC50 (200 µg/ml) niż wyciąg etanolowy (250 µg/ml) i wodny (400 µg/ml). Zauważono pozytywną korelację między całkowitym stężeniem fenoli i całkowitym stężeniem flawonoidów w wyciągach z E. pinnatum, a ich działaniem przeciwutleniającym i przeciwbakteryjnym.

    The higher fungi are a rich source of chemical compounds with multi-directional therapeutic and pro-health effects. This review summarizes the results of the most important chemical and biological studies of the fruiting bodies and the mycelial cultures of Laetiporus sulphureus. Numerous studies have demonstrated the antimicrobial, anticancer, cytotoxic, hypoglycemic anti-inflammatory and antioxidant activity of the extracts. Currently, only a few wood-decay fungi have practical use in medicine. Therefore it seems important to continue research on the effectiveness and safety of extracts and compounds of natural origin, including fungi, whose potential is not still used.

    Opis:
    Randia dumetorum (family Rubiaceae) is highly reputed ayurvedic medicinal tree commonly known as the Mainphal. A large deciduous thorny shrub grows up to 5 m of height. It occurs almost throughout India up to 1200 m of altitude. It is found in Himalaya from Jammu East ward ascending to 400 m and from Kashmir to East ward up to 1200 m. 11-methylixoside (compound 1), an iridoid glucoside, was isolated from the bark of this plant. The structure was characterized by using spectroscopic methods including 1D-1HNMR,13C-NMR and 2D-NMR (HSQC,HMBC, DQF-COSY) experiments and confirmed by comparison of their NMR data with those from the literature. This compound has been reported for the first time in Randia dumetorum bark. The 11-methylixoside was subjected to cytotoxic activity against MDA-MB-231 (breast cancer cell line) and SK-MEL-2 (human skin melanoma cell line), BE(2)C (neuroblastoma cell line derived from human bone marrow) and U87MG (human neuronale glioblastoma (astrozytom) cell line showed appreciable cytotoxic effect with IC50 value 63.10 µg/ml concentration for SK-MEL-2 (human skin melanoma cell line).
    Randia dumetorum (rodzina Apiaceae) jest rośliną cenioną w medycynie aiurwedyjskiej, znaną pod nazwą Mainphal. Duży, liściasty, ciernisty krzew osiąga wysokość 5 m. Występuje praktycznie w całych Indiach do wysokości 1200 m. Można go znaleźć w Himalajach od Jammu (400 m) do Kaszmiru (1200 m). Z kory tej rośliny wyizolowano glukozyd irydoidowy 11-metyloksyd (składnik 1). Jego strukturę zbadano za pomocą metod spektroskopowych obejmujących 1D-1HNMR,13C-NMR i 2D-NMR (HSQC,HMBC, DQF-COSY) i potwierdzono poprzez porównanie jego NMR danych z danymi literaturowymi. Obecność tego składnika stwierdzono po raz pierwszy w korze Randia dumetorum. Działanie cytotoksyczne 11-metyliksozydu było badane przeciw MDA-MB-231 (linia komórkowa raka sutka) i SK-MEL-2 (linia komórkowa czerniaka), BE(2)C (linia komórkowa neuroblastomy uzyskana z ludzkiego szpiku kostnego) i U87MG (linia komórkowa ludzkiej glioblastomy (gwiaździak). Wykazano znaczne działanie cytotoksyczne z wartością IC50 w stężeniu 63.10 µg/ml przeciw SK-MEL-2 (linia komórkowa czerniaka).

    Opis:
    The present investigation was carried out to analyse the presence of endophytes in the above-ground parts of Hipericum perforatum and to analyse the biodiversity and enumeration of epiphytes. Plant material was collected in Poland three times during the growing season. Phenotypic and genotypic diversity of all the endophytes and the most abundant epiphytes were researched. We analysed fungistatic activity of this isolates. From the endosphere of tested plant Alcaligenes faecalis and Bacillus licheniformis were isolated. The most numerous epiphytes were the copiotrophs and a bit less numerous were oligotrophs, bacteria cultivated on Bunt and Rovir’s medium and fungi. The least numerous bacteria were Azotobacter sp. Among all the molds dominant were: Cladosporium herbarum, C. cladosporioides and Alternaria consortialis, A. alternata, Clonostachys rosea f. catenulata (Gliocladium catenulatum), Scopulariopsis brevicaulis and Penicillium terrestre. Among phyllobacteria there were found mostly the following species: Burkholderia cepacia, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas fluorescens, P. putida, Pantoea agglomerans, Paenibacillus polymyxa, Bacillus cereus, Rhodococcus sp., R. erythropolis and Cellulosimicrobium cellulans. The broadest spectrum of antifungal activity was examined for the following species: Paenibacillus polymyxa, Pseudomonas putida and Pantoea agglomerans. P. polymyxa limited the growth of over 82% tested molds, so did the other two strains: P. agglomerans over 77% and P. putida over 73%.
    W przeprowadzonych badaniach oceniono występowanie bakterii endofitycznych w tkankach części nadziemnych Hypericum perforatum oraz poznania bioróżnorodności wspólnoty mikroorganizmów zasiedlających fyllosferę dziurawca. Rośliny zebrano na terenie Polski trzykrotnie w sezonie wegetacyjnym. W ich częściach nadziemnych oznaczono obecnośü bakterii endofitycznych oraz liczebnośü wybranych grup drobnoustrojów zasiedlających fyllosferę. Wyizolowane endofity oraz dominujące epifity poddano badaniom w celu oznaczenia ich przynależności taksonomicznej, a następnie oceniono ich aktywność antagonistyczną w kierunku wybranych pleśni. Z endosfery dziurawca wyizolowano szczepy należące do dwóch gatunków: Alcaligenes faecalis i Bacillus licheniformis. W fyllosferze dziurawca liczebnośü Azotobakter sp. była bardzo niska, natomiast najliczniejszą grupą były kopiotrofy, nieco mniej liczną bakterie oligotroficzne, bakterie wyrosłe na podłożach Bunta i Roviry i Kinga B oraz pleśnie i drożdże. Wśród pleśni dominujących stwierdzono Cladosporium herbarum, C. cladosporioides oraz Alternaria consortialis, A. alternata, Clonostachys rosea f. catenulata (Gliocladium catenulatum), Scopulariopsis brevicaulis i Penicillium terrestre. Wśród fyllobakterii dominowały w fyllosferze: Burkholderia cepacia, Klebsiella pneumoniae, Acinetobacter baumannie, Pseudomonas fluorescens, P. putida Pantoea agglomerans, Paenibacillus polymyxa, Bacillus cereus, Rhodococcus sp. R. erythropolis Cellulosimicrobium cellulans. Najszersze spektrum aktywności przeciwgrzybowej wobec testowanych pleśni stwierdzono dla szczepów Paenibacillus polymyxa, Pseudomonas putida oraz Pantoea agglomerans. P. polymyxa ograniczał wzrost ponad 82% badanych pleśni, P. agglomerans ponad 77%, a P. putida ponad 73%.

    Opis:
    The paper describes basic determinants of the medical plant cultivation in Polish agriculture. The author discussed economic background of the introduction of these plants indicating the role of pharmaceutical industry in herb usage. Then, there is a presentation of results of the survey study carried out among farmers from the Wielkopolska region. Approximately 10% of the farms cultivate medicinal plants but more than 50% declare some interest in this kind of production, what indicates a big potential. Farmers think that herbs are economically attractive crops if the sale is guaranteed and the price is satisfactory. The demand for medicinal plants is developing and expanding for e.g. dietary supplements and other health-promoting products. Therefore, it can be concluded that cultivation of medicinal plants is the prospective direction of agricultural production and an important element of additional income of Polish farmers.
    Artykuł przedstawia podstawowe uwarunkowania uprawy roślin zielarskich w polskim rolnictwie. Autor opisał tło ekonomiczne wprowadzania do struktury produkcji ziół, wskazując na rolę przemysłu farmaceutycznego w wykorzystaniu surowca zielarskiego. Następnie przedstawiono wyniki badań empirycznych przeprowadzonych wśród rolników województwa wielkopolskiego. Przeciętnie 10% gospodarstw uprawia zioła, ale połowa deklaruje zainteresowanie tymi roślinami, co świadczy o dużym potencjale produkcyjnym. Rolnicy uznają zioła za rośliny atrakcyjne ekonomicznie pod warunkiem gwarancji zbytu i dobrej ceny sprzedaży. Popyt na surowce zielarskie zależy od zapotrzebowania rynku leków roślinnych, który rozwija się i rozszerza o suplementy diety i inne artykuły prozdrowotne. Zatem uprawa roślin zielarskich jest perspektywicznym kierunkiem działalności rolniczej i stanowi ważne uzupełnienie w przychodach polskich gospodarstw.

    Opis:
    Lemon verbena is cultivated mainly due to the lemon-like aroma emitted from its leaves that are utilized for most purposes. The chemical composition of the essential oil of lemon verbena was analyzed by GC/MS in July at pre flowering, in September at full flowering and in end of October at post flowering period. The in vitro antimicrobial activity of the essential oil, extracted from Lippia citriodora was tested against laboratory control strains belonging to the American Type Culture Collection (Maryland, USA) four Gram (+) and Gram (-) bacteria using the disc diffusion test. Antioxidant activity of the sample was determined by 1,1-diphenil-2- -picrly-hydrazil (DPPH) assay. Well-known antioxidant compounds such as ascorbic acid and α-tocopherol were used as standard. Results showed, among different harvest periods high fresh and dry herbage and dry leaf yields per plant were obtained from full flowering stage. Harvest periods were found to have a significant effect on the content of essential oil and the highest amounts of limonene, neral and geranial and measured as 31.15, 11.92 and 15.53%, respectively at full flowering stage. In all samples, the main constituents were limonene, neral and geranial constituting 46.03%–58.59% of the total essential oil yield depend on development stages. Lemon verbena essential oil was found to have antibacterial activity especially against Gram (+) microorganisms. In DPPH system, the moderate radical scavenging activity was exhibited. Therefore, L. citriodora has potential to be used as a natural antioxidant and antimicrobial agent in food processing.

    Opis:
    Ceratophyllum demersum L. is a medical plant of the family Ceratophyllaceae that has been traditionally used for the treatment of diseases such as ulcer, diarrhoea, wounds and fever since ancient times. This study presents antioxidant activities of water and methanol extracts of in vitro propagated C. demersum. Shoot tip explants of C. demersum for in vitro plant regeneration were cultured on liquid Murashige and Skoog (MS) medium containing 0.25–1.25 mg/L 6-Benzylaminopurine (BAP) and 0.10 mg/L Thidiazuron (TDZ) combinations for eight weeks. Maximum number of plantlets per explant (110.67) was obtained on MS medium supplemented with 0.75 mg/L BAP + 0.10 mg/L TDZ. In order to determine antioxidant activities of C. demersum, antioxidant contents (β-carotene, flavonoid, lycopene and total phenols), metal chelating and reducing power capacities of methanol and water extracts obtained from C. demersum were investigated. It was detected that water extract was more effective in all activities. Total phenols (76.55 μg/mg) in water extract were measured as the highest antioxidant component. Based on the water extracts data, as IC50 value for chelating on ferrous ions was 9.24 mg/mL, EC50 value for reducing power activity was 8.23 mg/mL. It was also determined that the metal chelating and reducing power activities of the both extracts are increased depending on the concentration. Therefore, all these data suggest that both tested extracts of in vitro propagated C. demersum would exert beneficial effects by virtue of their antioxidant properties and may be utilized as a promising source of therapeutics.

    Introduction: Fungal disseases are the most common opportunistic infection. Objective: The main aims of the study were to determine phenolic content and to evaluate the antioxidant and anti-candida activity of the selected Indian-origin plant extracts from the fruit pulp, stem, leaves, and seeds of three plants of Indian origin. Material and methods: The extracts from Terminalia chebula, Thuja occidentalic and Syzygium jambolanum were investigated. The total phenolic content, antioxidant potential of different crude extracts was accessed using the free radical, 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). Anti-candida activity was evaluated using disk diffusion method and broth dilution assay against Candida albicans. Results: Ethanol and methanol extracts of Indian traditional plants possessed high radical scavenging activity: T. chebula 29.38±0.15, T. occidentalis 6.26±0.24 and S. jambolanum 25.64±0.18 at 0.32 mg/ml. The extracts exhibited good zones of inhibition diameters ranged between: for T. chebula 6.33±0.57 mm and 19.66±1.52 mm in diameter, S. jambolanum 7.00±00 mm and 23.33±1.52 and T. occidentalis 7.66±0.57 and 17.00±1.00 mm. C. albicans were susceptible to all three tested extract at different concentrations. The lowest MIC 1.95 mg/ml was recorded with S. jambolanum while the T. chebula and T. occidentalis inhibited the growth at 3.90 mg/ml, respectively, against the C. albicans. Conclusion: The study result paves an overall view on the bioactivities of three traditional Indian medicinal plants crude extracts.
