丹参脂溶性及水溶性成分集成提取工艺研究

Study on the Integration Technique for Extracting Liposoluble and Water-soluble Components of Salvia Miltiorrniza

目的优选丹参脂溶性及水溶性成分的集成提取工艺条件。方法采用正交设计法,以丹酚酸B、丹参酮ⅡA为测定指标,采用高效液相色谱法测定其含量,并以此为指标优选集成提取工艺条件。结果集成法可同时对丹参中脂溶性及水溶性成分进行提取。优选的提取工艺条件为:加8倍量70%乙醇,提取2次,每次1h。结论采用集成方法同时提取丹参水溶性及脂溶性部位,可省时、省工、节能,使丹参的提取工艺合理可行。

Objective To optimize an integration technique for extracting the liposoluble and water-soluble components of Salvia miltiorrhiza. Methods Salvianolic acid B and Tanshinone II A were selected as marker components and determined by HPLC to optimize the integration extract process of Salvia miltiorrhiza by orthogonal test. Results The liposoluble and water-soluble active components of Salvia miltiorrhiza were efficiently extracted by the optimum integration technique. The integration technique for extracting was obtained： Salvia miltiorrhiza was added with 8 times alcohol of 70% and extracted 1 hour for 2 times. Conclusion The liposoluble and water-soluble active components of Salvia miltiorrhiza can be extracted simultaneously by the novel extraction process which was reasonable and feasible. This new technique can be employed to reduce time, working and energy, and be suitable for the morden production.
