Using a two-phase solvent system composed of dichloromethane-methanol-n-butanol-water-acetic acid (5:5:3:4:0.1, v/v/v/v/v), high-speed countercurrent chromatography was successfully performed for isolation and purification of three iridoid glycosides from Fructus Corni for the first time. From 100 mg of a crude extract of Fructus Corni 7.9 mg of sweroside, 13.1 mg of morroniside, and 10.2 mg of loganin were obtained in less than 3 h with purities of 92.3, 96.3 and 94.2%, respectively. These target compounds were identified by ESI-MS, 1H NMR and 13C NMR.

山茱萸中环烯醚萜苷的制备分离纯化高速逆流色谱法。

使用二氯甲烷-甲醇-正丁醇-水-乙酸(5:5:3:4:0.1, v/v/v/v/v)组成的两相溶剂体系，高速逆流色谱成功首次从山茱萸中分离纯化三种环烯醚萜苷。从 100 mg 山茱萸粗提取物中，在不到 3 小时内分别获得了 7.9 mg 山茱萸苷、13.1 mg 莫诺苷和 10.2 mg 马钱苷，纯度分别为 92.3%、96.3% 和 94.2%。这些目标化合物通过 ESI-MS、1H NMR 和 13C NMR 进行鉴定。
