BACKGROUND To study the chemical constituents and larvicidal activity of essential oil extracted from the leaves of Coccinia grandis against three mosquito species. METHODS Essential oil was extracted by hydro distillation using clevenger apparatus and was analyzed for chemical constituents by gas chromatography-mass spectrophotometry (GC-MS). Larvicidal activity was recorded after 12 and 24h...

The chemical composition of essential oil and volatile obtained from the roots of Jatropha ribifolia (Pohl) Baill was performed in this work. The Clevenger extractor was utilized in hydrodistillation of oil and chemical composition determined by gas chromatography coupled with mass spectrometry detector (GC-MS). The identification of compounds was confirmed by retention index (Kovats index) obt...

Purpose: To determine the antimicrobial and antioxidant activities of Pulicaria inuloides and Ocimum forskolei essential oils. Methods: Steam distillation of the aerial parts of P. inuloides and O. forskolei was performed using a Clevenger apparatus. Essential oils were analyzed by gas chromatography–mass spectrometry. Total phenolic content and antioxidant activities were determined by 2,2-dip...

Abstract The essential oil (EO) composition of leaves Campomanesia aurea was analyzed by GC-MS. plant collected in April (EOA) and October (EOO) São Francisco de Assis/RS. oils were obtained hydrodistillation a modified Clevenger apparatus. yields 4.44% April, 6.15%, October. Thirty-one compounds identified EOA, accounting for 96.87% the total, twenty-eight EOO, 99.46% total. For major monoterp...

In this article, the chemical compounds, antimicrobial and antioxidant activity of volatile oil from leaves Olea europaea L. cultivar Turkey (Ayvalık) has been studied. The essential was provided with a Clevenger apparatus analyzed by GC-MS/FID. This analysis leads to detection 42 compounds representing 99.59±1.15% total oil. major constituents were a-pinene (9.82±0.33%), benzylalcohol (8.83±0....
