ABSTRACT Objective: To examine the influence of different factors on the stability of salvianolic acid B and to provide an experimental basis for their application in industrial production. Methods: Changes in the content of salvianolic acid B were determined by HPLC. Results: There was a significant effect of temperature and heating time on the stability of salvianolic acid B and salvianolic acid B was more stable in alcohol solution than in water. Conclusion: The temperature for the concentration of salvianolic acid B should be controlled below 60 ℃ and time within 4 hours,and higher concentrations of salvianolic acid B in the alcohol solution are of benefit to its stablity in the production process.

丹参来源于唇形科多年生草本植物丹参的干燥根及根茎,是我国传统中药之一。丹酚酸(salvianolic acids)是丹参药效成分中水溶性的酚酸类成分,具有较强的抗脂质过氧化和清除自由基作用,丹酚酸A和丹酚酸B是其中含量最高、活性最强的2个成分,抗心肌缺血与缺氧的活性比丹参素和原儿茶醛都强,近年来的研究表明,丹酚酸具有保护心肌细胞、抗动脉粥样硬化、防心脑缺血损伤、抗血小板凝聚、抗肝纤维化、改善记忆、抗肿瘤等作用[1-3]。丹酚酸不稳定,在水溶液中易降解,对温度很敏感,在高温、高压下很容易降解为丹参素等物质[4-6]。

丹参多酚酸盐是我公司的主要产品之一,是从丹参中提取的1组酚酸盐类成分,其中丹酚酸B的含量高达80%以上,丹酚酸类成分达100%,为了稳定产品质量和得率,我们对产品生产的工艺进行了研究,掌握了影响丹酚酸B稳定性的因素及关键工艺参数和操作方法,报道如下。
