摘要：

Two new steroidal glycosides, scopolosides I (1) and II (2), together with funkioside D (3) were obtained from the methanolic extract of the fresh underground parts of Scopolia japonica MAXIM. (SolanaCeae) collected in Hiroshima prefecture, and the chemical structures of 1 and 2 were characterized to be (25R)-spirost-5-ene-3beta,15alpha,23alpha-triol, named scopologenin (4), 3-0-beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucopyranosyl-(1 --> 4)-beta-D-galactopyranoside and scopologenin 3-0-beta-D-glucopyranosyl-(1 --> 4)-beta-D-galactopyranoside, respectively, by spectroscopic and chemical evidence.
