INFRA RED AND GAS CHROMATOGRAM-MASS SPECTRAL STUDIES OF THE ETHANOLIC EXTRACT OF ASCIDIA SYDNEIENSIS

Abstract

Ascidians have tremendous potential in pharmaceutical and biomedical field. Ascidia sydneiensis is commonly called as crevice ascidian. It has been subjected to Infrared (IR) spectral study which indicates the presence of aromaticity, hydroxyl and carbonyl group in the ethanolic extract. GC-MS studies revealed the presence of ten chemical constituents –Tetradecanoic acid, Bis-(2-methylpropyl)ester of 1,2-benzenedicarboxylic acid, n-Hexadecanoic acid, 9-Hexyl-heptadecane, Diisooctyl ester of 1,2benzenedicarboxylic acid, 3-ethyl-5-(2-ethylbutyl)-octadecane, Squalene, Cholest-5-en-3-ol(3∝)-carbonochloridate, Cholesterol, 2-[[2-[(2-ethylcyclopropyl)methyl]cyclopropyl]methyl]-methylester of cyclopropaneoctanoic acid.
