    Opis:
    Nothapodytes nimmoniana (J. Graham) (Icacinaceae), commonly known as Amruta is found in India particularly in Maharashtra, Goa, Kerala, Assam, Jammu and Kashmir as well as Tamilnadu areas. It is an important medicinal plant, the major source of a potent alkaloid, namely camptothecin, of a wide spectrum of pharmacological activities like anti-cancer, anti-HIV, antimalarial, antibacterial, anti-oxidant, anti-inflammatory, anti-fungal and also applied in the treatment of anaemia. Camptothecin is still not synthesized, therefore, its production entirely depends on natural sources. N. nimmoniana is one such plant which yields contain camptothecin in significantly high amount. The plant is gaining international recognition due to its diversified medicinal uses. It is subjected to excessive harvest. It has been categorized as a vulnerable and endangered plant. The present review encompasses the phytochemical, analytical, pharmacological, biotechnological, and other specific aspects of N. nimmoniana.
    Nothapodytes nimmoniana (J. Graham) (Icacinaceae), powszechnie znana jako Amruta, rośnie w Indiach, szczególnie w prowincjach Maharashtra, Goa, Kerala, Assam, Dżammu i Kaszmir, a także na niektórych obszarach Tamilnadu. Jest jedną z ważnych roślin leczniczych, głównym źródłem silnego alkaloidu, kamptotecyny, mającej szerokie spektrum działania: przeciwnowotworowe, anty-HIV, antymalaryczne, antybakteryjne, przeciwutleniające, przeciwzapalne, przeciwgrzybicze. Znajduje również zastosowanie w leczeniu anemii. Jak dotąd kamptotecyna nie została zsyntetyzowana, dlatego jej produkcja całkowicie zależy od źródeł naturalnych. N. nimmoniana jest jedną z roślin zawierających duże ilości kamptotecyny. Zyskała ona międzynarodowe uznanie dzięki szerokiemu spektrum zastosowań, co powoduje zwiększenie jej eksploatacji. Z tego powodu została uznana za gatunek zagrożony. Poniższy przegląd obejmuje badania fitochemiczne, analityczne, farmakologiczne, biotechnologiczne i inne prowadzone nad gatunkiem N. nimmoniana.

    Opis:
    Root-knot nematodes, genus Meloidogyne, are among the most plant damaging pathogens worldwide. The action of natural products against plant pathogens has been investigated to assess their effectiveness in the control of diseases. Thus, the present study aimed to evaluate the phytochemistry potential of the Ficus species for the control of Meloidogyne javanica. In vitro inhibitory activity assays were performed with crude ethanolic extracts of leaves and branches from 10 Ficus species. Among these, Ficus carica extracts exhibited strong paralysis activity against second stage juveniles (J2) (EC50 = 134.90 μg ∙ ml–1 ), after 72 hours. In addition, high efficacy was observed in egg-hatching inhibition at different embryonic stages. Microscopy analysis revealed severe morphological alterations in the nematode tissues at the J2 stage, as well as immotility of juveniles released from eggs in the presence of F. carica extracts. The efficacy of the treatments for the other species was very low. These differences were supported by the variation in the compound classes, mainly for alkaloids and metabolite profiles by Gas Chromatography/Mass Spectrometry (GC/MS) when F. carica was compared with the other species. The results indicated that F. carica is a promising source for the isolation and identification of molecules capable of acting in the control of M. javanica.

    Opis:
    In this study, we sought to find and employ positive effects of UV-A irradiation on cultivation and quality of microgreens. Therefore, the goal of our study was to investigate the influence of 366, 390, and 402 nm UV-A LED wavelengths, supplemental for the basal solid-state lighting system at two UV-A irradiation levels on the growth and phytochemical contents of different microgreen plants. Depending on the species, supplemental UV-A irradiation can improve antioxidant properties of microgreens. In many cases, a significant increase in the investigated phytochemicals was found under 366 and 390 nm UV-A wavelengths at the photon flux density (12.4 μmol m-2 s-1). The most pronounced effect of supplemental UV-A irradiation was detected in pak choi microgreens. Almost all supplemental UV-A irradiation treatments resulted in increased leaf area and fresh weight, in higher 2,2–diphenyl–1–picrylhydrazyl free-radical scavenging activity, total phenols, anthocyanins, ascorbic acid, and α-tocopherol.

    Opis:
    Oak acorns used to be an important human food, up until recent times. The major factor inhibiting their use in modern nutrition is their high tannin content. Polish oak trees were screened in order to find out whether there are any major geographical or interspecific differences in tannin and total phenolic contents in acorns, which might help us to establish further directions in the search for low-tannin individuals. We studied the level of phenolic compounds using the standard Polish and European Pharmacopoeia method, with Folin-Ciocalteu reagent and hide powder. Altogether 49 acorn samples of Quercus robur, 13 of Q. petraea, 1 of Q. pubescens (all native) and 12 of Q. rubra (introduced) were collected in different regions of Poland. The amount of investigated phenolics in Q. robur and Q. petraea acorns was similar, and tannins constituted the main component. The Q. pubescens sample was distinguished by the lowest tannin and total phenolic content and a relatively high amount of non-tannin phenolics. Q. rubra had a slightly lower tannin content than Q. robur and Q. petraea acorns, but the level of other phenolics was much higher. The results for Q. robur suggest geographical variability of phenolic content as well as a relationship between the phytochemical and biometric parameters of oak acorns.

    Opis:
    Introduction: Solanum sodomaeum L. has been observed to have several medicinal properties, in particular, in the treatment of several types of human skin cancer. Objective: The influence of the maturation stage of S. sodomaeum fruits on the total lipid contents, fatty acid profiles, essential oil yields and compositions, as well as the antibacterial and antioxidant activities of the essential oils, was investigated. Methods: The fatty acid and essential oil constituents were identified using gas chromatography (GC) and GC–mass spectrometry (GC–MS). The antioxidant properties of essential oil and vegetal oil were assessed using 1,1-diphenyl-2-picryl-hydrazyl (DPPH) scavenging and reducing power assays. The antibacterial ac-tivity of essential oil was tested using the disc diffusion assay for resistance in human pathogenic bacteria. Results: Mature fruits showed higher total lipid content (17%) and were characterised by polyunsaturated fatty acids (53.87%), represented mainly by linoleic acid (53.11%). Similar yields of essential oils were detected for immature (0.43%) and mature (0.45%) fruits. Tetrahydronaphthalene (41.79%) was detected as the major essential oil component at the immature stage versus dihydrocoumarin pentane (18.27%), hexadecanoic acid (17.43%) and 2-undecanone (13.20%) in mature fruits. The DPPH test showed that essential oils had better antioxidant properties; however, the vegetal oils showed better performance in the reducing power assay. Moreover, the essential oil of S. sodomaeum mature fruits was active against bacterial strains. Conclusions: S. sodomaeum fruits could be a valuable source of natural antioxidants and antibacterial agents.

    Opis:
    Opuntia species belong to semi-arid and arid regions of Mexico and the United States. O. ficus-indica and O. dillenii are commonly used in alternative medicine to treat various diseases. Up to date, several scientific works have been carried out on the different parts of these plants. However, over the last few years, studies have been focusing on the oil obtained from the fruit seeds of these species. For this reason, this study aims to draw the attention of researchers toward the phytochemical and the pharmacological effects of these two Opuntia oils, which would help set up other scientific projects that promote these products. Phytochemical studies have shown that these oils are rich in biologically active molecules, such as unsaturated fatty acids and phytosterols (mainly linoleic acid and β-sitosterol), as well as vitamin E, which is represented only by the γ-tocopherol. Besides, these oils are rich in polyphenols that protect them from photo-oxidation. Moreover, several studies have shown their antioxidant, anti-diabetic, antibacterial, antifungal, anti-inflammatory,hepatoprotective, and gastroprotective activities, as well as their hypolipidemic properties. The beneficial effects of these oils include also their ability to block the weight loss, and what makes them more interesting is their safety, according to the literature.

Jest to krzew o długim korzeniu palowym, który dziko rośnie w całych Indiach. Ekstrakty roślinne przygotowano przy użyciu etanolu, metanolu i wody destylowanej jako rozpuszczalników. Aktywność przeciwutleniającą oznaczono za pomocą DPPH (2,2-difenylo-1-pikrylohydrazyl-hydrat) neutralizując wolne rodniki i wyznaczając IC50. Całkowita zawartość związków flawonoidowych znaleziona w ekstrakcie etanolowym Aerva javanica wynosiła (0,90 ±0,16), podczas gdy całkowita zawartość fenoli znaleziona w ekstrakcie etanolowym wynosiła (0,78 ±0,16), a następnie w ekstrakcie metanolowym i wodnym. Wyniki antyoksydacyjne ekstraktu metanolowego z Aerva javanica wykazały 0,78 ±0,18 procent inhibicji, a SCV 49,10% przy stężeniu 1,5 mg/ml, ekstrakt etanolowy wykazał 0,54 ±0,12 procent inhibicji z 64,28% SCV. Analizę fitochemiczną ekstraktu Aerva javanica przeprowadzono techniką chromatografii gazowej ze spektrometrią mas (GC-MS). Wyniki wykazały obecność różnych związków, głównie acetonu (1,18%), octanu etylu (38,95%), (20,77%), octanu n-propylu (4,09%), octanu izobutylu (2,71%), (3,84%), izochinoliny, 1-[(3,4-dietoksyfenylo) metylo]-6,7-dietoksy- (3,36%), cykloheksanon (1,43%), 1,1-diizobutoksy-izobutan (2,02%), kwas n-heksadekanowy (5,61%), fitol (3,57%), kwas 9-oktadecenowy, ester 1,2,3-propanotriylowy (10,72%), kwas oktadekanowy (1,78%), ftalan bis(2-etyloheksylu) (3,48%), skwalen (1,40%), 2,2-dimetylo-3-3,7,16,20-tetrametyl (1,12%) i 1,6,10,14,18,22-tetrakozaheksaen-3-ol (1,195%). Potrzebne są badania mające na celu wykrycie większej liczby nowych związków w celu opracowania skutecznych metod zarządzania, które znacznie zmniejszą wpływ patogenów na zdrowie człowieka, a także na środowisko.

    Opis:
    A global society, including developed countries, continues to struggle with fatal diseases that are difficult to treat with Western medicine. A variety of infectious diseases have existed for ages, but in Africa they had been limited thanks to the Indigenous Knowledge System (IKS) prior to the introduction of cosmopolitan medicine. Influenza virus repression has been demonstrated by a number of herbal antivirals, yet the invaluable therapeutic potential of herbal medicine has been underestimated. Despite various reliable methods offered by Western medicine, the globally destructive COVID-19 pandemic requires a successful fight. The wisdom of African IKS used in tackling epidemics that have broken out in the past is brought to mind again. Pneumonia – a COVID-19 symptom, could be treated with polyherbal fomentation. Selected plants cultivated across Nigeria for hydrotherapy are under consideration to be used in proper doses. Given the potential associated with IKS, a multi-disciplinary approach involving experts in phytomedicine, ethnobotany, phytochemistry, plant physiology and ecology is necessary to unlock the therapeutic potential of traditional medicine.

    Opis:
    Posidonia oceanica seagrass is endemic to the Mediterranean, and has very little information about volatile organic compounds. The plant was collected from Garyounis Beach in Benghazi, east of Libya, in September 2019. Plant parts, leaves, rhizomes, and roots were extracted using a Soxhlet extractor with Hexane. The compounds were characterized by gas chromatography-mass spectrometry. the extract's chemical constituents were de-convoluted using AMDIS software (www.amdis.net), and the mass spectra of the compounds spectra were explained by fragmentation pattern and matched to authentic standard spectra from Wiley and the NSIT Library database. The results revealed sixteen compounds, dominated by nine long-chain hydrocarbons, three long-chain fatty acids, and a single long-chain ketone. This is the first discovery of 3-ethyl-5-(2ethyl-butyl-octadecane, 6,10,14-trimethylpentadecan-2-one, phytol, and phytyl acetate from this plant.
