虎杖乙醇渗漉液中总蒽醌含量的实验研究

Experimental study on the manufacture procedure of Rhizoma Ploygoni cuspidati ethanol extraction

目的 确定虎杖乙醇渗滤液中以大黄素为标准的总蒽醌含量的最佳提取条件。方法 采用L9(34)正交设计 ,以大黄素为标准 ,以分光光度法对虎杖乙醇渗滤液中总蒽醌进行实验研究。结果 最佳提取条件为A3 B3 C1D2 即用 30倍量 70 %乙醇渗漉二次每次 2h。结论 本实验结果可靠 ,方法简便 。

OBJECTIVE To confirm the best procedure for Rhizoma Ploygoni cuspidati ethanol extraction. METHOD The procedure was optimized by orthoral test.RESULTS The best condition for procedure was to apply 70% ethanol, thirty times of the weight of original material, extraction two time and each extraction times was 2h.CONCLUSION The result is credible,the method is simple . It can be used for batch production.
