Seven compounds were isolated from the stems of Mucuna macrocarpa Wall. (Fabacae ). On the basis of spectral data and chemical reactions, their structures were elucidated as lupenone (Ⅰ ), friedelin (Ⅱ ), 6-sitosterol (Ⅲ ), △5,22 -stigmasten-3?-ol (Ⅳ), tetracosanoic acid 2,3-dihydroxypropyl ester (Ⅴ ), pentacosanoic acid 2, 3-dihydroxypropyl ester (Ⅵ ),hexacosanoic acid 2,3-dihydroxypropyl ester (Ⅶ). Ⅵ is a new compound, while Ⅴ and Ⅶwere obtained from nature for the first time.
