摘要:

采用高速逆流色谱(HSCCC)结合液相色谱法制备甘青青兰(Dracocephalum tanguticum Maxim.)中绿原酸、胡麻甙-6″-乙酯、迷迭香酸,建立快速分离制备甘青青兰中活性成分的方法。采用半制备型高效液相色谱(SP-HPLC)富集甘青青兰乙酸乙酯萃取物中绿原酸、胡麻甙-6″-乙酯、迷迭香酸,再用制备液相(Pre-HPLC)和HSCCC对富集物进行分离纯化,获得54 mg化合物Ⅰ、130 mg化合物Ⅱ和200 mg化合物Ⅲ,纯度分别为96.9%、97.9%和95.1%,经核磁共振碳谱(13CNMR)和氢谱(1HNMR)分别鉴定为绿原酸、胡麻甙-6″-乙酯和迷迭香酸。本实验方法适用于甘青青兰乙酸乙酯萃取物中绿原酸、胡麻甙-6″-乙酯和迷迭香酸的分离制备,并避免了传统分离方法操作繁多、试剂消耗量大、不可回收等弊端,为分离甘青青兰活性成分、制备对照品等研究提供了参考依据。

Abstract:

An efficient method was established for the separation and preparation of chlorogenic acid, pedaliin-6″-acetate and rosmarinic acid from Dracocephalum tanguticum Maxim.. The chlorogenic acid, pedaliin-6″-acetate and rosmarinic acid was enriched by semi-preparative high performance liquid chromatography(SP-HPLC) from ethyl acetate extract, and then separated and purification by high-speed counter-current chromatography(HSCCC) and preparative high performance liquid chromatography(Pre-HPLC). A total of 54 mg of chlorogenic acid, 150 mg of pedaliin-6″- acetate and 200 mg of rosmarnic acid were obtained from ethyl acetate extract with purities of 96.9%, 97.9% and 95.1% by HPLC analysis, respectively. Their structures were identified by nuclear magnetic resonance spectrum. The result show that this method is suitable for the isolation and purification of chlorogenic acid, pedaliin-6″-acetate and rosmarnic acid from D. tanguticum. It also avoids the disadvantages of traditional separation methods such as many operations, large reagent consumption and non-recyclability, provides a reference basis for the study of separating of active components and preparation reference substance from D.tanguticum.

Key words: high-speed counter-current chromatography, preparative high-performance liquid chromatography, Dracocephalumtanguticum Maxim., chlorogenic acid, Pedaliin-6″-acetate, rosmarnic acid
