The essential oil composition from the leaves of Strychnos axillaris Colebr. (Loganiaceae) growing in Malaysia was examined for first time. obtained by hydrodistillation and fully characterized gas chromatography (GC-FID) chromatography-mass spectrometry (GC-MS). In total, 15 components were identified oil, which made up 87.2% total oil. is composed mainly ?-ionone (20.2%), ?-ionone (19.5%), bi...

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...

Background: Thymus daenensis is on e of the endemic aromatic species in Iran that its essential oil is used in food and pharmaceutical industries. Objective: In this study, the effects of plant growth stages and distillation methods on essential oil content and thymol percentage of this species were evaluated. Methods: The aerial parts of Th. daenensis were collected in three stages of plan...
