The present investigation aimed at to determine the probable phytochemical components from the non-polar to polar extracts of Caralluma attenuata. The compound extracted was subjected to UV, IR, 1H NMR,13C NMR, DEPT and SEPT. The resultant spectral data was used to elucidate the compound. The first compound was named as CAR-1 which gave a positive result with Liebermann-Burchard reaction. Spectral data showed that it contains thirty eight carbon resonances, side chain contains ten carbons and one terminal double bond, primary hydroxyl groups, and eight methyls, fifteen methylenes, ten methynes and five quarternary carbons. From the mass spectrum of CAR-1 the peak at m/z 555 (M+H)+ is considered as a base peak with molecular formula C38H66O2. The second compound was named as CAR-2 which is also a white crystalline solid and gave a positive result with Liebermann-Burchard reaction. Spectral data showed that CAR-2 contains 38 carbon resonances. In that side chain contains ten carbons which has α,β-unsaturated alcohol. From the mass spectrum of CAR-2 the peak at m/z 570 is considered as the molecular ion peak with molecular formula C38H66O3. The results indicating the compounds isolated are steroid/terpenoid. © 2016, International Journal of Pharmacognosy and Phytochemical Research. All rights reserved.
