Volatile phytochemical composition of rhizome of ginger after extraction by headspace solid-phase microextraction, petroleum ether extraction and steam distillation extraction
The sampling techniques headspace solid-phase microextraction (HS-SPME), petrol ether extraction (PEE) and steam distillation extraction (SDE) were compared for the GC-MS of volatile constituents present in ginger (Zingiber officinale). The effects of different parameters, such as extraction fibers, extraction time, extraction temperature and particle size ranges, on the HSSPME of rhizome of gi...
متن کاملChemical Analysis of Volatile Constituents of Pulicaria Mauritanica Isolated by Hydrodistillation and Headspace Solid-phase Micro-extraction Techniques. Antimicrobial Activity of its Essential Oil
The objective of this study is to report the comparative chemical analysis of essential oil (EO) obtained by hydrodistillation (HD) and volatile fraction (VF) detected by headspace solid phase micro-extraction (HS–SPME) isolated from Pulicaria mauritanica using Gas Chromatography–Retention Indices (GC-RI) and GC–Mass Spectrometry (GC-MS) and to evaluate in vitro the antimicrobial activity of P....
متن کاملHeadspace Solid Phase Microextraction in Pesticide Residues Analysis: 1. Optimisation of Extraction Conditions
The method of headspace solid phase microextraction (HS/SPME) was successfully used in a simultaneous multicomponent analysis of hexachlorobenzene (HCB), tefluthrin, heptachlor, aldrin, chlorpyrifos, fenthion and bifenthrin in aqueous medium. Measurements were performed using a nonpolar polydimethyl siloxane (PDMS) fiber. Detection and quantification were done by gas chromatography/mass spectro...
متن کاملSimultaneous Distillation Extraction of Some Volatile Flavor Components from Pu-erh Tea Samples—Comparison with Steam Distillation-Liquid/Liquid Extraction and Soxhlet Extraction
A simutaneous distillation extraction (SDE) combined GC method was constructed for determination of volatile flavor components in Pu-erh tea samples. Dichloromethane and ethyl decylate was employed as organic phase in SDE and internal standard in determination, respectively. Weakly polar DB-5 column was used to separate the volatile flavor components in GC, 10 of the components were quantitativ...
