Lipid profile and biological activity of different extracts of Stapelia hirsuta L.

β-amyrin (1), lupeol (2), α-amyrin (3) and β-sitosterol (4) were isolated from the n-hexane extract. GLC analysis of (USM) and (FAME) revealed that, squalene, α-amyrin and β-sitosterol are the major hydrocarbon, triterpene and sterol respectively. The percentages of the unsaturated and saturated fatty acids are 40.8% and 48% respectively. Caproic acid (26.6%) was the major fatty acid and stearic (1.2%) being the minor one. Biological screening of the different extracts and fractions were carried out and significant results were obtained.
