摘要: 采用快速制备液相色谱从库拉索芦荟中高效分离制备10-羟基芦荟大黄素苷A和B。以库拉索芦荟药材粉甲醇提取物为原料,采用快速制备液相色谱,EYELA柱(300 mm × 20 mm i.d.,20~45 μm),甲醇-水为流动相(35:65,v/v)等度洗脱,流速10 mL/min,检测波长356 nm,对芦荟样品进行分离制备,得到2种化合物单体,经UV、旋光度、HRMS和NMR鉴定,HPLC测定纯度,2个化合物分别为10-羟基芦荟大黄素苷B(98.9%)和10-羟基芦荟大黄素苷A(98.2%)。该方法简便、快速,所得产物纯度较高,可用于对照品的制备和药理毒理活性研究。

Abstract: 10-hydroxyaloins A and B,two anthrones from Aloe vera, were successfully separated by reversed-phase flash chromatography on a C18column(300 mm × 20 mm i.d.,20-45 μm) eluting with methanol-water(35:65,v/v) at a flow rate of 10 mL/min.In a one-step operation,6.5 mg of 10-hydroxyaloin B and 4.7 mg of 10-hydroxyaloin A were isolated from 200.0 mg of A.vera extract at purities of 98.9% and 98.2%,respectively.The structures of the two compounds were characterized on the basis of spectroscopic evidences (NMR,HRMS,UV and optical rotationdata) and literature data.The procedure offered a simple,fast and efficient method for the preparation of reference substances of 10-hydroxyaloins A and B which can be used for the further study on their analysis and biological properties.
