摘要：

By phytochemical investigation of the leaves of Premna japonica, four monoacyl 6-0-α-L-rhamnopyranosylcatalpols were isolated. The structures of these compounds were established to be 6-0-α-L-(2ʺ-0-trans-p-coumaroyl)rhamnopyranosylcatalpol (saccatoside) [1], 6-0-α-L-(4ʺ-0-trans- and cis-p-coumaroyl)rhamnopyranosylcatalpols [3], 6-0-α-L-(2ʺ-0 caffeoyl)rhamnopyranosylcatapol [5], and 6-0-α-L-(3ʺ-0-caffeoyl)rhamnopyranosylcatalpol [7]. © 1990, American Chemical Society.
