A butyrolactone lignan disaccharide from Flacourtia ramontchi.
beta-Sitosterol, beta-sitosterol-beta-D-glucopyranoside and a butyrolactone lignan disaccharide, ramontoside, were isolated from the heartwood of Flacourtia ramontchi. The structure of ramontoside was determined as diphyllin-4-O-[beta-D-glucopyranosyl(1---4)]-beta- 2,3-di-O-methyl-D-xylopyranoside by hydrolysis and spectral data.
