Two new cis-eudesmane sesquiterpene glycosides, liriopeoside A (1) and ophiopogonoside A (2), were extracted and purified from tubers of Liriope muscari and Ophiopogon japonicus, respectively, along with three known compounds. Their structures were elucidated as 1beta,6beta-dihydroxy-cis-eudesm-3-ene-6-O-beta-D-glucopyranoside (1) and 1beta,4beta,6beta-trihydroxy-cis-eudesmane-6-O-beta-D-glucopyranoside (2) by spectral data analysis. The structure and the relative configuration of compound 1 were confirmed by X-ray crystallographic analysis. This is the first time that cis-eudesmane-type sesquiterpenes have been reported from the genera Ophiopogon and Liriope.
从麦冬和沿阶草的块茎中分别提取并纯化出两种新的顺式桉叶烷倍半萜糖苷,即麦冬苷A(1)和沿阶草苷A(2),同时还得到了三种已知化合物。通过光谱数据分析,它们的结构被鉴定为1β,6β - 二羟基 - 顺式桉叶 - 3 - 烯 - 6 - O - β - D - 吡喃葡萄糖苷(1)和1β,4β,6β - 三羟基 - 顺式桉叶烷 - 6 - O - β - D - 吡喃葡萄糖苷(2)。化合物1的结构和相对构型通过X射线晶体学分析得到证实。这是首次从沿阶草属和麦冬属植物中报道顺式桉叶烷型倍半萜。
