The present work reports the <i>in vitro</i> antimicrobial activities of the essential oil and methanol extract from <i>Satureja hortensis</i> as well as the content of its essential oil. The chemical composition of hydrodistilled essential oil of Satureja hortensis was analysed by means of GC-MS. Thirty constituents were identified. The main constituents of the oil were thymol (40.54%), &gamma;-terpinene (18.56%), carvacrol (13.98%), and <i>p</i>-cymene (8.97). The essential oil of <i>Satureja hortensis</i> exhibited the activity against 25 bacteria, 8 fungi, and a yeast, <i>C. albicans</i>; exerting the Minimum Inhibitory Concentration values (MIC) ranging from 15.62 to 250 &micro;l/ml. Similarly, methanol extract of the plant also showed antimicrobial activity.

Objective: In the present study, the essential oil, methanol extract, and methanol fractions (n-hexane, chloroform, ethyl acetate, and n-butanol) obtained from Commelina nudiflora were investigated for the free radical scavenging effects and phytochemical analysis.Methods: The antioxidative effect of the essential oil, methanol extracts and methanol fractions were evaluated using 2, 2 diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. Total phenolic and flavonoid contents were determined using Folin-Ciocalteau and aluminium chloride reagents respectively. The phytochemical analyses of the essential oil, methanol extracts and methanol fractions were performed by gas chromatography and mass spectrometry (GCMS). Results: The antioxidant, total phenolic and total flavonoid contents of butanol, ethyl acetate and chloroform fractions were higher followed by methanol extract, hexane fraction and essential oil. Phytochemical analysis indicated the presence of alkaloid, saponin, steroid, phytosterols, triterpenoids and tannins etc. The identified bioactive constituents of essential oil, methanol extract and methanol fractions of C. nudiflora were indole, 2-methoxy-4-vinylphenol, 2-pentadecanone, 6,10,14-trimethyl, phenol, benzyl alcohol, eugenol, phenol, 2, 4-bis (1,1-dimethylethyl), hexadecanoic acid, ethyl ester (palmitic acid ester), n-hexadecanoic acid (palmitic acid), 9, 12-octadecadienoic acid, (linoleic acid) and phytol. All identified bioactive compounds and their derivatives were generally reported with antimicrobial, antioxidant, anti-inflammatory and antitumor properties.Conclusion: The obtained data suggest that the essential oil, methanol extract and methanol fractions of C. nudiflora possess remarkable antioxidant activities and vital phytochemicals. Thus the plant can be a utilized as a potential source of nutraceutical with antioxidant activity.

Oleogum resins of B. papyrifera, B. neglecta, and B. rivae were collected from northwestern, southern, and southeastern Ethiopia, and their respective methanol extracts and essential oils were extracted and analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The investigation on essential oils led to the identification of 6, 7, and 8 constituents for B. papyrifera, B. neglecta, and B. rivae, respectively. The essential oil of B. papyrifera is mainly characterized by the presence of octyl acetate (57.1–65.7%) and n-octanol (3.4–8.8%). B. neglecta is rich in α-pinene (32.6–50.7%) followed by terpinen-4-ol (17.5–29.9%) and α-thujene (12.7–16.5%), whereas B. rivae was predominated by α-pinene (32.5–66.2%) followed by p-cymene (5.7–21.1%) and limonene (1.1–19.6%). Methanol extracts of the three Boswellia species were found to consist of diterpines (incensole, incensyl acetate and verticilla-4(20),7,11-triene), triterpenes (β-amyrin, α-amyrin, β-amyrenone, and α-amyrenone), nortriterpenes (24-noroleana-3,12-diene and 24-norursa-3,12-diene), and α-boswellic acid. The investigation on the methanol extract showed that only B. papyrifera contains diterpenes and nortriterpenes, whereas B. rivae and B. neglecta consist of only triterpenes. The results indicate that the three Boswellia species were characterized by some terpenes and these terpenoic constituents could be recognized as chemotaxonomical markers for each species.

Phytochemical investigations of Alchemilla persica Rothm. growing in Iran were performed taking into account both the volatile and polar constituents. The hydrodistilled essential oil was analysed by GC-MS that revealed the presence of alkanes (27.8%), diterpenoids (19.6 %) and sesquiterpene hydrocarbons (17.1%) as the major constituents, while tannins and flavonol glycosides were identified as the most abundant constituents of the methanol extract by HPLC-MS. A. persica can be a valuable source of ellagitannins and polyphenols.
