  Two diacyl rhamnopyranosylcatalpols were isolated from the leaves of Premna japonica. The structures of the compounds were determined to be 6-O-α-L-(2"-O-isoferuloyl, 4"-O-acetyl)rhamnopyranosylcatalpol and 6-O-α-L-(3"-O-isoferuloyl, 4"-O-acetyl)rhamnopyranosylcatalpol. The locations of acyl moieties were determined by long-range proton selective decoupling experiments and by partial alkaline hydrolysis.

  从白花蛇舌草（Premna japonica）的叶子中分离出了两种二酰基鼠李糖基宿主酚。化合物的结构被确定为 6-O-α-L-（2"-O-异阿魏酰，4"-O-乙酰基）rhamnopyranosylcatalpol 和 6-O-α-L-（3"-O-异阿魏酰，4"-O-乙酰基）rhamnopyranosylcatalpol。酰基的位置是通过长程质子选择性解偶联实验和部分碱性水解来确定的。

  Abstract From the methanol extract of the leaves of Premna japonica , two new monoacyl 6- O -α- l -rhamnopyranosyl-catalpols were isolated. The structures of these compounds were determined to be 6- O -α- l -(2″- O -isoferuloyl and 3″- O -isoferuloyl)rhamnopyranosylcatalpols by NMR spectroscopy and chemical conversions.
