Abstract:
Studying on Clausena lansium (Lour.) samples collected from Pu Mat, Nghe An province in March 2004 to isolate and determine structure of some sterol compounds. Bough samples were dried and pounded leached with methanol in 20 days. Methanol extract was collected via distilling process to get solvents. Extracting with ethyl acetate, n-butanol and then distilling to get solvent we collected corresponding sediments. The corresponding solid extracts were collected by extract method with ethyl acetate, n-butanol solvents and then segment distill. A1, A2 solids were isolated by chromatographic method and segment crystallization. Using EI - MS, 1H - NMR, 13C - NMR spectroscopic methods to determine structure, A1 were identified as beta - sitosterol and A2 as stigmasterol. This is the first time these compounds isolated from Clausena lansium (Lour.) in Vietnam
