GC-MS Analysis of Ethyl Acetate Fraction of the whole Plant Extract of <i>Dyschoriste perrottetii (Acanthaceae)</i>

Abstract

The present investigation was carried out to determine the bioactive components in the ethyl acetate extract of D. perrotiettii (Acanthaceae) using GC-MS analysis. The compounds identified in the ethyl acetate fraction were 9-Octadecenal (53.78%), Hexadecanoic acid (22.82%), Octadecanioc acid or Stearic acid (10.68%), 2-methylnonane (3.42%) and 9, 12-Octadecadenoic acid or Linoleic acid (2.84%). FTIR analysis of the compound showed two strongly adsorbing peaks at about 3000 and 2850 cm^-1 corresponding to CH of an alkane, OH stretch of carboxylic acid respectively. The peak at 1740.98 cm^-1 corresponds to C=O stretching frequency for carboxylic acids. The peak at 1662.4 cm^-1 is assigned for carbonyl group (C=O) in carboxylic acid and the weak peak at 1155.97 cm^-1 corresponds to the C-O stretch of an alcohol or carboxylic acid.
