摘要：

Two diacyl rhamnopyranosylcatalpols were isolated from the leaves of Premna japonica. The structures of the compounds were determined to be 6-0-a-L-(2“-0-isoferuloyl, 4”-0-acetyl)rhamnopyranosylcatalpol and 6-0-a-L-(3“-O-isoferuloyl, 4”-0-acetyI)rhamnopyranosylcatalpol. The locations of acyl moieties were determined by long-range proton selective decoupling experiments and by partial alkaline hydrolysis. © 1990, The Pharmaceutical Society of Japan.
