摘    要:为开发从丹参中提取高纯度丹酚酸B的新工艺,采用水提-壳聚糖絮凝-过滤-浓缩-醇沉-萃取工艺制得丹酚酸B含量在80%左右的丹酚酸提取物EB80。用硅胶柱层析法精制EB80,得到丹酚酸B含量为96%的提取物EB96。EB96的IR、M S1、H-NMR测试结果表明:其分子结构特征、相对分子质量与丹酚酸B相同。本工艺便于工业化实施。

关 键 词:丹参  丹酚酸B  提取工艺

Abstract:A new technology of extracting salvianolic acid B with high concentration from Salvia mihiorrhiza bunge was developed. The craft of water extraction-chitosan flocculation-fihration-concentrationethanol sedimentation-liquid-liquid extraction with organic solvents was applied to obtain extract EB80, whose content is about 80%. EB80 was purified by column adsorption, extract EB96,whose content of sal- vianolic acid B is 96%, was obtained. IR,MS and ^1H-NMR detection of EB96 shows that the sample has the same structural characteristics and relative molecular moment as those of salvianolic acid B. The technology is convenient to be industrialized.
Keywords:Salvia miltiorrhiza bunge  salvianolic acid B  extraction technology
