Opis:
The essential oil from flowering Marrubium (Marrubium vulgare L.) an aromatic member of the Lamiaceae family, from Algeria, obtained by hydrodistillation, was analysed by GC/FID and GC/MS. The constituents were identified by their mass spectra and Kovats’ indices. Fivety (50) components in the oil of M. vulgare were identified. The results demonstrated that the major components of the essential oil were: 4,8,12,16-Tetramethyl heptadecan-4-olid (16.97 %), Germacrene D-4-ol (9.61 %), α- pinéne (9.37 %), Phytol (4.87 %), Dehydro-sabina ketone (4.12 %), Piperitone (3.27 %), δ-Cadinene (3.13 %), 1-Octen-3-ol (2.35 %) and Benzaldehyde (2.31 %). Essential oil of M vulgare was evaluated for its antibacterial activities against Gram-positive and Gram negative pathogenic bacteria: Bacillus subtilis, Micrococcus luteus, Escherichia coli and Klebsiella pneumoniae.

Opis:
In previous work [1], the essential oil of the aerial parts of Marrubium vulgare L. obtained by hydrodistillation was analysed by gas chromatography coupled to mass spectrometry (GC-MS) in order to determine their chemical composition. Fifty (50) components in the oil of M. vulgare were identified. The results demonstrated that the major components of the essential oil were: 4,8,12,16-Tetramethyl heptadecan-4-olid (16.97 %), Germacrene D-4-ol (9.61 %), α- pinéne (9.37 %), Phytol (4.87 %), Dehydro-sabina ketone (4.12 %), Piperitone (3.27 %), δ-Cadinene (3.13 %), 1-Octen-3-ol (2.35 %) and Benzaldehyde (2.31 %). In this study, the antioxidant properties of essential oil were examined. The results showed that this oil can be considered an effective source of antioxidants of natural origin. This is the first report on chemical composition of M. vulgare essential oil cultivated in Algeria and the original study on the antioxidant activity of M. vulgare essential oil. The antioxidant activity was investigated with one method: 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method.

Opis:
The insecticidal properties of essential oil derived via the hydro-distillation method from aerial parts of Artemisia judaica L. were tested against the cowpea weevil, Callosobruchus maculatus (Fab.) (Coleoptera: Bruchidae). The repellent activity assay of essential oil against C. maculates adults indicated that in concentrations of 63.7, 31.9, 15.9, 8.0 or 4.0 μg/cm2, the oil reduced egg laying by 92.5, 86.0, 61.8, 42.7 and 12.5%, respectively. Also, the residual-film assay showed that after 72 hours of treatment, concentrations of 50 and 40% were highly effective against the C. maculates adults. The sub-lethal effects of essential oil were investigated on fecundity and F1 progany by exposing adult females to treated seeds. Both LC25 and LC50 of essential oil significantly reduced F1 progany production compared to the control. The chemical composition of the essential oil was analyzed by GC-MS and the resulting oil piperitone (32.4%), camphor (20.6%) and (E)-ethyl cinnnamate (8.2%) were found to contain the major constituents of the oil. This provided the insecticidal properties of the essential oil against cowpea weevil.

Opis:
This study analyzed chemical composition of the essential oils (EOs) of Thymus vulgaris L., harvested in two regions of northwest Algeria (Tlemcen and Mostaganem), and evaluated their antimicrobial and cytotoxic activity. Fifty one compounds representing 99.99% and 100% of total thyme oil of Mostaganem (EO.TM) and Tlemcen (EO.TT), respectively were identified by GC-FID and GC-MS. Carvacrol was a dominant compound in both oils (89.15 and 82.42%). The antimicrobial activity, demonstrated by disc diffusion and broth macrodilution methods, showed a strong inhibitory effect of the oils on seven reference strains tested and particularly on Bacillus cereus ATCC 10876 and Candida albicans ATCC 10231. A cytotoxicity assay for two normal and two cancer cell lines indicated the highest sensitivity of canine B-cell lymphoma cell line (CLBL-1) for which IC50 values were 35.39 ± 9.0 (EO.TT) and 84.51± 3.2 (EO.TM). Murine fibroblast cell line (3T3), with IC50 116.97 ± 2.7 for EO.TT and 146.29 ± 0.5 for EO.TM was the most resistant line.

Opis:
Six coriander accessions of different origins were grown on an experimental field in Mošorin, Serbia during 2014. The GC/MS analysis of the essential oil showed that the major components in all samples were linalool (69.3–72.0%), γ-terpinene (6.0–9.6%) and α-pinene (6.7–8.2%), while other compounds were present at less than 5%. Antifungal activity of coriander oils against two phytopathogenic fungi from Colletotrichum genus (C. acutatum and C. gloeosporioides) was evaluated using the inverted petriplate method. Experiments show that coriander essential oil has antifungal properties against the apple bitter rot pathogens from Colletotrichum genus, but only at higher application rates (≥ 0.16 μl/ml of air). According to the obtained data, it can be concluded that tested coriander accessions differ in essential oil content and composition, as well as in influence on mycelial growth. Coriander essential oil has potential for being applied as a biological control agent against these two fungi from Colletotrichum genus.
Sześć populacji kolendry różnego pochodzenia uprawiano na polu doświadczalnym w Mošorin w Serbii w 2014 roku. Analiza GC/MS olejku lotnego wykazała, że głównymi składnikami we wszystkich próbkach były linalol (69,3–72,0%), γ-terpinen (6,0–9,6%) oraz α-pinen (6,7–8,2%), natomiast inne składniki były obecne w ilości mniejszej niż 5%. Przeciwgrzybicze działanie olejków kolendry względem dwóch grzybów fitopatogenicznych z gatunku Colletotrichum (C. acutatum i C. gloeosporioides) oceniono za pomocą metody odwróconych szalek Petriego. Doświadczenia wykazały, że olejek eteryczny kolendry ma właściwości antygrzybicze względem patogenów gorzkiej zgnilizny jabłoni pochodzących z gatunku Colletotrichum, ale tylko przy większych dawkach aplikacji (≥ 0,16 μl/ml powietrza). Na podstawie uzyskanych danych można wyciągnąć wniosek, że badane populacje kolendry różnią się zawartością olejku eterycznego oraz wpływem na wzrost grzybni. Olejek eteryczny kolendry posiada potencjał jako środek ograniczający dwa grzyby z gatunku Colletotrichum.

Opis:
The purpose of this study was to evaluate the photochemical, antioxidants and anticancer activity of the medicinal plant Aerva javanica. This plant belongs to the Amaranthaceae family. Locally it is called “bui”. It is a shrub with a long tap root that grows all over India in the wild. The plant extracts were prepared using ethanol, methanol and distilled water as solvents. The antioxidant activity was determined using DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) free radical scavenging activity and IC50 was determined. The total flavonoids compounds found in Aerva javanica ethanolic extract were (0.90 ±0.16) while the total phenolic contents found in ethanolic extract were (0.78 ±0.16), followed by the methanolic and aqueous extract. The antioxidant results of methanolic extract of Aerva javanica showed 0.78 ±0.18 percent inhibition and SCV 49.10% at concentration of 1.5 mg/ml, ethanolic extract showed 0.54 ±0.12 percent inhibition with 64.28% SCV. Phytochemical analysis of best result oriented Aerva javanica extract was done with Gas Chromatography-Mass Spectrometry (GC-MS) technique. The results revealed the presence of different compounds predominantly Acetone (1.18%), Ethyl Acetate (38.95%), (20.77%), n-Propyl acetate (4.09%), Isobutyl acetate (2.71%), (3.84%), isoquinoline,1-[(3,4-diethoxyphenyl)methyl]-6,7-diethoxy- (3.36%), Cyclohexanone (1.43%), 1,1-Diisobutoxy-isobutane (2.02%), n-Hexadecanoic acid (5.61%), Phytol (3.57%), 9-Octadecenoic acid, 1,2,3-propanetriyl ester (10.72%), Octadecanoic acid (1.78%), Bis(2-ethylhexyl) phthalate (3.48%), Squalene (1.40%), 2,2-Dimethyl-3-(3,7,16,20-tetramethyl (1.12%) and 1,6,10,14,18,22-Tetracosahexaen-3-ol (1.195%). The study concludes that extensive research is required to detect more novel compounds in order to develop effective management approaches that significantly reduce the impact of the pathogens on human health as well as on environment.
Celem pracy była ocena fotochemicznej, antyoksydacyjnej i przeciwnowotworowej aktywności rośliny leczniczej Aerva javanica. Ta roślina należy do rodziny Amaranthaceae. Lokalnie nazywa się „bui”. 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%).

Opis:
Phenol is one of the main pollutants that have a serious impact on the environment and can even be very critical to human health. The biodegradation of phenol can be considered an increasingly important pollution control process. In this study, the degradation of phenol by Pseudomonas fredriksbergsis was investigated for the first time under different growth conditions. Six different initial concentrations of phenol were used as the primary substrate. Culture conditions had an important effect on these cells' ability to biodegrade phenol. The best growth of this organism and its highest biodegradation level of phenol were noticed at pH 7, temperature 28 °C, and periods of 36 and 96 h, respectively. The highest biodegradation rate was perceived at 700 mg/L initial phenol concentration. Approximately 90% of the phenol (700 mg/L) was removed in less than 96 hours of incubation time. It was found that the Haldane model best fitted the relationship between the specific growth rate and the initial phenol concentration, whereas the phenol biodegradation profiles time could be adequately described by the modified Gompertz model. The parameters of the Haldane equation are: $0.062 h^{−1}$, 11 ppm, and 121 ppm for Haldane’s maximum specific growth rate, the half-saturation coefficient, and the Haldane’s growth kinetics inhibition coefficient, respectively. The Haldane equation fitted the experimental data by minimizing the sum of squared error (SSR) to $1.36×10^{-3}$.

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.

Phytochemical Analysis
Opis:
Garcina kola leaves were collected, washed, dried and powdered. The ethanol extracts were first prepared by the simple method of cold extraction. The extracts were then characterized by the Phytochemical analysis, Fourier transform infrared spectroscopy (FTIR) and Gas chromatography mass spectroscopy (GC-MS) to identify the fatty acids and heterocyclic compounds present in the leaf extracts. The FTIR analysis shows a variation of the peaks that indicate there is synergy among the functional groups of the extract. Moreover, the phytochemical analysis revealed the presence of alkaloids, flavonoids, phenol, saponins, tannins and steroids. The study reveals that the chemical constituents of Garcina kola leaf may be behind their medicinal values in phytomedicine.

Stosowano metodę GC-MSD dla ekstraktów roślinnych otrzymanych w różnych rozpuszczalnikach organicznych: metanolu, chloroformie, toluenie. Uzyskane wyniki posłużyły do charakterystyki profilu chromatograficznego olejku pochodzącego z Calea zacatechichi oraz opracowania metody identyfikacji Psychotria viridis na podstawie modelu zbudowanego za pomocą analizy głównych składowychskładowych (Principal Component Analysis, PCA). W olejku Calea zacatechichi stwierdzono występowanie związków typowych dla rodziny Astraceae. Były to głównie izoprenoidy (terpeny), a wśród nich pochodne germakranu. Analiza GC-MS ekstraktów z Psychotria viridis wykazała obecność substancji psychoaktywnych w postaci dimetylotryptaminy (DMT) i niewielkich ilości metylotryptaminy. Analiza głównych składowych (PCA) zastosowana dla P. viridis na łączonych danych z różnych rozpuszczalników pozwoliła na stwierdzenie, że otrzymane wyniki prezentują dostatecznie wysoki stopień podobieństwa i możliwa jest identyfikacja gatunkowa rośliny opisaną metodą.
The aim of this article was to elaborate the chromatographic profile of two psychoactive plants: Calea zacatechichi and Psychotria viridis. The GC-MS method, based on extraction in different organic solvents, i.e. methanol, chloroform, toluene and alkalized chloroform was applied. The obtained data was used to characterize the chromatographic profile of the oil produced from Calea zacatechichi and to elaborate a new method of identification of Psychotria viridis based on a statistical model built using PCA (Principal Component Analysis). The Calea zacatechichi oil contains chemical compounds typical for the Astraceae family, i.e. terpenes (derivatives of germacrene). GC-MS analysis of Psychotria viridis revealed presence of psychoactive substances: dimethyltriptamine (DMT) and methyltriptamine. The PCA of the Psychotria viridis on combined data from different solvents proved that the obtained data demonstrates a sufficient degree of resemblance to allow identification of species by the described method.

Opis:
Fixation is a necessary tea processing step that affects the quality of tea, including its aroma. However, there are no guidelines to follow whether the Cyclocarya paliurus leaves need to be fixated to produce tea. The aim of this study was to determine the volatile metabolites in fixated and unfixated C. paliurus tea by gas chromatography-mass spectrometry in order to identify the volatile compounds that differentiate them and establish the key aroma compounds. Compared with the unfixated tea, the fixated tea had higher contents of amines, phenols, nitrogen compounds, ether, alcohol, terpenoids, ester and aromatics. A total of 147 metabolites that differentiated both types of teas were identified using principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). Among them, 22 and 25 volatile compounds of teas processed without and with fixation, respectively, had relative odor activity values greater than 1. These metabolites had green, fruity, sweet, woody, herbal, floral, fresh, spicy, earthy and waxy odor. This study showed that fixation technology improved the quality of C. paliurus tea, which provided the basis for the production of C. paliurus tea, and promoted the standardization of the preparation technology of C. paliurus tea.

Opis:
Masson pine (Pinus massoniana) is an important species for resin tapping in China. Molecular assisted selection (MAS) has been gradually introduced in to the selection and breeding of masson pine. Until now, the lack of connection between genome information and phenotypic data has hindered the breeding and selection of important chemical compounds of xylem resin. In this study, gas chromatography mass spectrometer (GC-MS) was employed for qualitative and quantitative analysis of chemical compounds of resin collected from 69 masson pine germplasm resources. Then, genome-wide association study (GWAS) was conducted for the terpenoids with higher heritability. A total of 15 primary compounds, including six diterpenes and nine monoterpenes/sesquiterpenes, were detected from xylem resin. By using five GWAS methods, 42 associated SNPs were identified from these masson pines. The P. taeda genome database was used for detecting candidate genes related to the associated SNPs. By using transcriptome data, several members of PKc_like super family, Cytochrome P450, AP2-ERF, F-box, and ABC transporter were found to be highly expressed in the masson pines with higher resin-yielding capacity. The terpenoids associated SNPs can be directly used for MAS. These candidate genes, especially the two F-box members, will contribute to the study of terpenoid biosynthesis mechanisms in the future.
