摘要: 采用高速逆流色谱分离制备药桑花色苷。以甲基叔丁基醚-正丁醇-乙腈-水-三氟乙酸(2:2:1:5:0.01,V/V)为溶剂体系,进样量50mg,分离得到纯度分别为99.24%、88.5%、99.9%和96%的4个花色苷单体。通过高速逆流色谱(HSCCC)、紫外-可见光谱、质谱进行结构鉴定,初步确定馏分1为矢车菊-3-O-芸香糖苷,馏分2为天竺葵-3-O-芸香糖苷,馏分3为矢车菊-3-O-葡萄糖苷,馏分4为天竺葵-3-O-葡萄糖苷。此法高效、稳定、简捷易行。

Abstract: This study dealt with the isolation of anthocyanins from Morus nigra Linn. fruits grown in Xinjiang by high-speed countercurrent chromatography (HSCCC). The solvent system used consisted of methyl tert-butyl ether, butanol, acetonitrile, water and trifluoroacetic acid (2:2:1:5:0.01, V/V). Fifty-gram sample was injected. As a result, 4 individual anthocyanins with purities of 99.24%, 88.5%, 99.9% and 96%, respectively, were obtained. They were identified by HSCCC, UV-vis spectroscopy and LC-MS as cyanidin-3-O-rutinoside, pelargonidin-3-O-rutinoside, cyanidin-3-O-glucoside and pelargonidin-3-O-glucoside, respectively. The HSCCC method was efficient, stable, simple and easy.
