GC-MS ANALYSIS OF SOME BIOACTIVE CONSTITUENTS OF THE LEAVES OF DESMODIUM GYRANS DC

Abstract

Desmodium gyrans DC is one of the medicinally valuable plants belonging to the family Fabaceae, commonly known as “Thozhukanni” in Tamil and ‘ Namaskari’ in Sanskrit. Traditionally leaves are used as antidote, cardiac-tonic and for wound healing. In the present study the ethanolic extract of Desmodium gyrans has been subjected to GC-MS analysis. Eighteen chemical constituents have been identified, The major chemical constituents are: 4,5-Dihydro-2- amino-4-(2,4-dichlorophenyl)-7-methyl-5-oxo- pyrano[3,2-c]pyran-3-carbonitrile (59.07%), Pentaborane (13.86%), Pentanedinitrile (6.63%) and 3-Chloro-1-

butyne, (4.82%).
