Abstract A new ellagic acid glycoside, 3,3′-di- O -methyl ellagic acid 4′-rutinoside, along with 3,4,3′-tri- O -methyl ellagic acid 4′-rutinoside and 3,4,3′-tri- O -methyl ellagic acid have been isolated from the rhizomes of Euphorbia acaulis . The structures of these compounds have been established on the basis of spectral ( 1 H NMR, 13 C NMR, MS, IR, UV) and chemical evidence.
摘要 一种新的鞣花酸苷,3,3'-二-O-甲基鞣花酸4'-芸香苷,以及3,4,3'-三-O-甲基鞣花酸4'-芸香苷和3,4,3 '-三-O-甲基鞣花酸已从大戟的根茎中分离出来。这些化合物的结构是在光谱( 1 H NMR、 13 C NMR、MS、IR、UV)和化学证据的基础上确定的。
