Abstract
Five known compoxmds (carbonylbis[imino(6-methyl-3,l-phenylene)]}bis[carbamic acid] dimethyl ester (1), (1'R,3'S,5'R,8'S,2E,4E)-dihydrophaseic acid 3'-0->B-D-glucopyranoside (2), 3- methylbutan-l-ol j5-D-glucopyranoside (3), asttagalin (4) and daucosterol (5) were isolated from the methanol extract of the seeds of Scaphium macropodum (Miq.) Beumée. The structures of the isolated compounds were elucidated by specừoscopic methods including NMR and MS, and also by comparison with the literature data. Compoimds 1-3 were isolated from this plant for the first time.
