This study examined the chemical composition of essential oil extracted from bark Alseodaphne peduncularis Meisn. (Lauraceae) by hydrodistillation with 0.2% yield. The was chemically characterised gas chromatography-flame ionization detector and chromatography-mass spectrometry, 31 constituents comprising 94.3% total content were identified. These included β-caryophyllene (24.5%), viridiflorol ...

background & aim: essential oils are isolated from different sections of plants such as flowers, seeds, leaves, stems and roots. essential oils are applied extensively in producing of perfumes, cosmetics, foods, beverages and confectioneries and as ingredients of disinfectants and insecticides. experimental: essential oil are obtained by several isolation methods, such as hydrodistillation ...

Abstract Recently, there has been a growing interest in natural products of plant origin as herbal remedies. In this study, the profile bioactive volatile organic compounds and odorous sample Pistacia lentiscus L. vegetable oil determined. The study indicated that extraction yield is influenced by method, conditions, stage maturity sampling area. Analysis HS‐SPME‐GC–MS GC–MS showed monoterpenes...

The essential oils (EOs) of the aerial parts of Lippia origanoides (LiOr), collected in different localities of the Amazon region, were obtained by hydrodistillation and analyzed by GC and CG-MS. Principle component analysis (PCA) based on chemical composition grouped the oils in four chemotypes rich in mono- and sesquiterpenoids. Group I was characterized by 1,8-cineole and α-terpineol (LiOr-1...

The aim of this research was to determine chemical composition and insecticidal activity of the essential oil of Illicium pachyphyllum fruits against two grain storage insects, Sitophilus zeamais and Tribolium castaneum, and to isolate any insecticidal constituents from the essential oil. The essential oil of I. pachyphyllum fruits was obtained by hydrodistillation and analyzed by GC-MS. A tota...
