In the present study, chemical composition and antibacterial properties of essential oil obtained from the aerial parts of the Melicope pteleifolia (Champ. ex Benth.) T.G Hartley in Dalat were evaluated. Essential oil was isolated through hydro-distillation. Twenty-nine constituents comprising 100% of the essential oil were characterized by gas chromatography/mass spectrometry (GC-MS) techniques. The major compounds in the essential oil were (+)-Sabinene (34.73%), Cis-α-bergamotene (13.15%), Z-α-trans-bergamotol (5.28%), β-mycrene (4.98%), and 1,3,6-octatriene, 3,7-dimethyl-(4.71%). Antibacterial activities of Melicope pteleifolia essential oil were investigated against Gram-positive and-negative bacteria. Results showed significant activities against Streptococcus pyogenes and Escherichia coli using an agar well diffusion method. The application of this essential oil in preventing and eliminating bacteria could be useful in fields as medicine and cosmetics.

The purpose of our study was to bring elements of knowledge on the anticancer and antibacterial effects of two plants, widely used in Moroccan traditional pharmacopeia. These plants are: Marrubium vulgare and Euphorbia resinifera. The aerial parts of each plant were extracted successively with Hexane, Dichloromethane, and finally with methanol. The MTT-based method was applied to evaluate the cytotoxicity of the cancer cells: animal cells BSR and Vero and human cell RD. We evidenced an anticancer activity of the extract of the Marrubium vulgare and the dichloromethane extract of Euphorbia resinifera against the studied cells. The antibacterial activity was evaluated for three species of Rhodococcus: Rhodococcus equi, and strains GK1, GK3, grown in a liquid medium, or this medium solidified with agar. In the last test, the method is based on substance diffusion from well throughout the solid medium. The obtained profiles showed that the growth of bacteria is strongly inhibited by the extracts of Marrubium vulgare. However, the extracts of Euphorbia resinifera had no significant effect on bacterial growth. The chemical analysis of the raw extracts of Marrubium vulgare and Euphorbia resinifera by GC-MS analysis showed the presence of several major chemical compounds, mainly: octadecane, 2,6,10,15-tetramethylheptadecane, 2,6,10-trimethyltetradecane, linoleic acid, and deisopropylatrazine. Our observations an encouraging for deepening the studies of the extracts, in order to target better the active molecules, isolate them and to determine their mechanisms of action. The suggested studies would result in the much better valorization of these two medicinal plants.

Two new prenylated isoflavonoids, namely Erinasone A and Erinasone B along with 19 known secondary metabolites, including twelve isoflavonoids, three polyphenols, one flavonol, two flavanones and three steroids, were isolated from the whole plant (roots and aerial parts) of Erinacea anthyllis. Structures of all isolated compounds were elucidated by spectroscopic analysis, including 1D and 2D NMR (1H, 13C, COSY, HSQC, TOCSY, HMBC and NOESY), mass spectrometry (ESI-MS), UV-Vis, measurement of optical rotation [α]D and by comparison with the literature data. The total phenolic and flavonoid contents were determined in this study. Furthermore, the antioxidant and antibacterial activities of the EtOAc and n-BuOH extracts of E. anthyllis were evaluated. These extracts exhibited moderate antibacterial and antioxidant activities. Their IC50 values were approximately 0.04 mg/mL ( n-BuOH) and 0.037 mg/mL (EtOAc). Consequently, Erinacea anthyllis is a rich source of polyphenolic compounds particularly isoflavonoids used as chemotaxonomic markers for the subfamily Papilionoideae of the family Fabaceae.

A comparison of the chemical composition, and antioxidant and antibacterial activities of the essential oils obtained from the aerial parts of Thymus caucasicus, T. kotschyanus, and T. vulgaris was carried out. The oils, obtained by hydrodistillation, were analyzed by GC and GC/MS. Twenty, 29 and 22 compounds representing 94.8%, 96.6% and 98.2% of the essential oils of T. caucasicus, T. kotschyanus and T. vulgaris, respectively, have been identified. The oil of T. caucasicus was characterized by 1,8-cineol (21.5%), thymol (12.6%), β-fenchyl alcohol (8.7%), nerolidol (7.8%), terpinolene (7.2%), α-pinene (7.0%) and myrcene (6.8%). In the oil of T. kotschyanus, carvacrol (24.4%), β-caryophyllene (14.5%), γ-terpinene (12.4%), α-phellandrene (10.8%), p-cymene (9.8%) and thymol (6.8%) were the predominant compounds, whereas the main components of T. vulgaris oil were thymol (43.8%), p-cymene (15.2%), germacrene-D (11.7%), terpinolene (3.4%), carvacrol (3.2%), β-caryophyllene (2.8%) and α-thujene (2.2%). In all three plants oil, hydrocarbon monoterpenes predominated over sesquiterpenes. Antioxidant activities were assessed by determining IC50 values in the DPPH radical scavenging assay. Antibacterial activity was determined by measuring minimum inhibitory concentration (MIC) using the broth dilution method. The essential oils of T. caucasicus, T. kotschyanus and T. vulgaris showed free radical scavenging and antibacterial activity.

Corydalis and Pseudofumaria are two closely related genera from the Papaveraceae subfamily Fumarioideae with Corydalis solida (C. solida) and Pseudofumaria lutea (P. lutea) as two representative species. Phytochemical analysis revealed significant differences in the quality and quantity of isoquinoline alkaloids, phenolic compounds and non-phenolic carboxylic acids between aerial and underground parts of both species. Using the Liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) technique, 21 compounds were identified: five protoberberine derivatives, three protopine derivatives, four phenanthridine derivatives, as well as three carboxylic acids, two hydroxycinnamic acids, one chlorogenic acid, one phenolic aldehyde, and two flavonoids. Moroever, significant differences in the content of individual compounds were observed between the two studied species. The phytochemical profile of C. solida showed a higher variety of compounds that were present in lower amounts, whereas P. lutea extracts contained fewer compounds but in larger quantities. Protopine was one of the most abundant constituents in C. solida (440–1125 µg/g d.w.) and in P. lutea (1036–1934 µg/g d.w.). Moreover, considerable amounts of coptisine (1526 µg/g) and quercetin (3247 µg/g) were detected in the aerial parts of P. lutea. Extracts from aerial and underground parts of both species were also examined for the antimicrobial potential against S. aureus, P. aeruginosa and C. albicans. P. lutea herb extract was the most effective (MIC at 0.39 mg/L) against all three pathogens.
