Stipa capensis, the Mediterranean needle-grass, is an annual grass of the genus stipa, in the Poaceae family. It is normal found in the Persian Gulf desert ad semi-desert biome. This plant is indigenous to the Fars, Khuzestan, and west of Iran. In traditional medicine, stipa capensis have been used for illness related to the Nerve system problems and gastric discords. The goal of this study is to identify and characterize the phytochemical compound present in this valuable medicinal plant. This is the first report of the presence of phytochemical in stipa capensis. Stipa capensis is commonly known as Bahman in Iran. The leaves of the plant Stipa capensis was collected from Masjede-Soleiman, Khuzestan, Iran in March, 2015.Basic phytochemical screening from the aerial parts of stipa capensis revealed the presence of terpenoids and steroids. The powdered sample was extracted and was further fractionated successively with n-hexane and methanol.The nonpolar fraction was subjected to column. The separated constituents were subjected to LC-MS and GC-MS study. The spectrum of the unknown compounds was compared with the spectrum of the component stored in the NIST (National Institute Standard and Technology) library.The results pertaining to LC-MS analysis led to the identification of number of terpenes from fraction of the hexane extract of Stipa capensis.This is the first report of the screening and isolation of phytochemical in stipa capensis. This study reports the isolation and identification of terpenoid extracted from stipa capensis on fraction 1and 4 isolated that led to isolation of terpenoid compounds (carotenoids, steroids, cardiac glycosides and prenol lipids.)
