Sarcostemma acidum (Roxb.) Voigt is a valuable medicinal plant to treat a number of diseases in India. Four compounds were isolated from the whole plant of S. acidum. The structures were characterized as Friedelin (1), β-amyrin (2), β-sitosterol (3) and 4α-Carboxy-4β-methyl-5α-cholesta-8,24-dien-3β-ol (4) by extensive spectroscopic (NMR, FT-IR and mass) analysis and compared their spectral data with literature. The in vitro anti-inflammatory activity of isolated compounds (1-4) and extract of S. acidum was carried out against the denaturation of protein using egg albumin method compared with standard dichlofenac sodium. The compounds showed the inhibition of protein denaturation in a concentration dependent manner.
