GC-MS analysis of root methanolic extract of Gynochthodes ridsdalei Razafim. and B. Bremer, an endemic, endangered species of southern Western Ghats of India

Abstract

The present investigation was carried out to determine the presence of biologically active components in the root methanolic extract of Gynochthodes ridsdalei using Gas Chromatography–Mass Spectrometry (GC-MS) analysis. Fresh root of G. ridsdalei collected from the forest areas of Ponmudi hills of Thiruvananthapuram district of Kerala State, India was used for the study. The active principles with their retention time, peak area, molecular weight and molecular formula of the compounds were detected. The analysis revealed the presence of 26 components. The components were identified by comparing their retention time and peak area with that of literature available and by the interpretation of mass spectra.
