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

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.
