摘要
目的:建立茯苓中三萜成分的含量测定方法。方法:紫外分光光度法,波长(243±1)nm。结果:对照品在8.4-42.0μg·mL^(-1)范围内具有良好的线性关系,r=0.9999,平均回收率为99.95%(n=9),方法精密度实验 RSD=0.65%。结论:本法简便,快速,准确,重复性好。适用于茯苓中三萜成分的分析测定。
Objective:To develop a method for the determination of triterpene in Poria cocos (Schw.) Wolf.Meth- od:UV spectrophotometric method wavelength was (243±1) nm.Results:The range of calibration curve was 8.4- 42.0 μg·mL^(-1)(r=0.9999).The average recovery was 99.95% (n=9).The precision (RSD) was 0.65%.Con- clusions:The method is simple,rapid,accurate and good reappearance.
