Abstract

Repeated fractionation of the acetylated methanol extract of Prasium majus afforded acetylated derivatives of a new iridoid glycoside hamighriprasin (1), myoporoside (2), beta-D-glycopyranose (3) and saccharose (4). The structures of 1 and 2 were established by interpretation of 1D and 2D NMR data of their corresponding acetylated derivatives and by comparison with the literature.

摘要

对海滨刺芹的乙酰化甲醇提取物进行反复分馏，得到了一种新的环烯醚萜苷——海滨刺芹苷（1）、水甘草苷（2）、β-D-吡喃葡萄糖（3）和蔗糖（4）的乙酰化衍生物。通过对其相应乙酰化衍生物的一维和二维核磁共振数据进行解析，并与文献进行比较，确定了化合物1和2的结构。
