摘要
目的:改进15版《中国药典》收载的土茯苓中落新妇苷含量测定方法。方法:以60%甲醇为溶剂,分别用回流法、超声提取法制备供试品溶液,其余色谱条件同药典进行测定。结果:60%甲醇溶液超声提取法测定落新妇苷含量较60%甲醇溶液回流提取法更高。结论:采用改进后的测定方法能够真实反映土茯苓中落新妇苷含量,有利于对单味土茯苓及复方中的质量控制。
Objective： To improve the methed of aualyze the amount of astilbin in Smilax glabra, which listed in the 15 th edition of the Chinese Pharmacopoeia was optimized. Methods： Using 60% methanol as solvent,the sample solution was prepared by reflux method, and followed by ultrasonic extraction, and the amount of astilbin was determined by chromatography as instructed in the Pharmacopoeia. Results： Using 60% methanol solution, the amount of astilbin obtained by ultrasonic extraction was higher than by refluxing extraction.Conclusion： The optimized extraction method can accurately measure the actual amount of astilbin in Smilax glabra, which provides a better quality control in analyzing the amount of astilbin in single or compound Smilax glabra.
