論文の詳細を見る
Two new acyl glycosides, leucosceptosides A (IV) and B (V), have been isolated from Leucosceptrum japonicum (MIQ.) KITAMURA et MURATA, together with martynoside (III), acteoside (I) and an acteoside isomer (II). The structures of IV and V were determined to be 2-(3,4-dihydroxyphenylethyl) 1-O-α-L-rhamnopyranosyl-(1→3)-β-D-(4-O-caffeyl)-glucopyranoside and 2-(3-hydroxy-4-methoxyphenylethyl) 1-O-α-L-rhamnopyranosyl-(1→3)-O-[β-D-apiofuranosyl (1→6)]-β-D-glucopyranoside, respectively, on the basis of chemical and spectral data.
