GC-MS ANALYSIS OF ETHANOL EXTRACT OF ENTADA PURSAETHA DC SEED

The investigation was carried out to determine the possible bioactive components of seed of Entada pursaetha using GC-MS. Entada pursaetha known to the Kanikkars as “Parandaikodi” is an important medicinal plant. The Kanikkar tribe, inhabitants of Agasthiarmalai Biosphere Reserve, Western Ghats, Tamil Nadu use this plant to relief from rheumatic pain. The chemical compositions of the ethanol extract of seed of Entada pursaetha were investigated using Perkin-Elmer Gas Chromatography-Mass Spectrometry, while the Mass spectra of the compounds found in the extract was matched with the National Institute of Standard and Technology (NIST) library. Fourteen compounds were identified; 1,2, Benzenedicarboxylic acid, diisooctyl ester (69.52%) was found to be major component followed by Benzeneacetic acid, 2,5-dihydroxy- (syn: Homogentisic acid) (8.12%), n-Hexadecanoic acid (4.48%) Oleic acid (4.39%) Azulene, 1,4-dimethyl 1-7- (1-methylethyl)- (3.86%) and undecanoic acid (2.46%).
