The aim of this study was the development and validation of a new method for carbohydrates analyses obtained from woody biomass, as a step of bioethanol production. In this study, we have quantified carbohydrates in wood by gas chromatography (GC) after derivatization. Quantification of carbohydrates was made by liquid-liquid extraction, oximation and silylation and, finally, analysis by gas ch...

The aim of this study is to evaluate the bioactive compounds in the ethanolic leaf extract of Azima tetracantha by using Gas chromatographyMass Spectrometry (GCMS). Azima tetracantha leaves were collected from Ariyalur District, Tamil Nadu. The dried leaf powder was extracted with the solvent ethanol by using Soxhlet apparatus. One microlitre of the extract was subjected for analysis by GCMS to...

The present study was aimed at analysis of bioactive constituents of leaves from Abutilon indicum. The ethyl acetate extract of the leaves were subjected to Fourier transform infrared spectroscopy (FT-IR) and Gas chromatographymass spectroscopic (GCMS) analysis. GC-MS analysis of plant extract was performed using a Perkin-Elmer GC Clarus 500 system and Interpretation on mass spectrum GC-MS was ...
