Comparative Study of the Essential Oils from Hemidesmus indicus and Decalepis hamiltonii

Abstract

The essential oils from the dry roots of Decalepis hamiltonii and Hemidesmus indicus were analyzed by GC and GC-MS. Five and seven compounds respectively were identified. 2-Hydroxy-4-methoxybenzaldehyde was found to be the major component in D. hamiltonii (96.29 %) as well as H. indicus (97.89 %). In addition, a comparison of the essential oils from previously investigated fresh and these dry roots of H. indicus was done which showed that 2-hydroxy-4-methoxybenzaldehyde was not lost during drying.
