The present study has aimed to identify the Phyto-substance present in Ichnocarpus frutescens using GC-MS analysis. The root part was extracted by maceration in which we have taken 70% Ethyl alcohol and 30% of distilled water. The phyto-components of Hydroalcoholic extract were identified by GC-MS investigation and eight were identified by GC-MS investigation and found eight numbers of phyto-components. Phyto- constituents of the extracts were D-Ribo-Hexose, 2, 6-dideoxy-3-O-methyl-, Diethyl Phthalate, Desulphosingrin, 3-O-Methyl-d-glucose, d-Mannose, Ethyl Oleate, Hexadecanoic acid, 2 Hydroxy-1-(hydroxymethyl) ethyl ester, Octadecanoic acid, 2-hydroxy-1-(Hydroxymethyl) ethyl ester. This study is the major characterization of the phyto-components of plant data that indicates the hydro-alcoholic extract has remarkable activities.
