摘要
采用双波长薄层扫描法测定新疆雪莲芦丁含量。以乙酸乙酯一甲酸一水(67:13:20)为展开剂,硅胶GF254薄层析分离;测定波长λs为263nm,参比波长λR为235nm。样品回收率为97.3%;相对标准偏差为2.8%。在芦T0.5~6.0μg范围内有良好的线性,相关系数为0.999。本法简便、快速、灵敏度高。
Rutin in Saussurea Involucrata was separated by TLC on a
silica gel plate with EtOAC一HCOOH一H2O(67:13 : 20)as developing system,Rutin was determined
by using Shi-madzu CS一930 dual wave length:263 nm and reference wave length:235 nm with
satisfac-tory results.Calibration curve was rectilinear for 0. 50~6.0 μg with a corelation
coefficientof 0.999 the average recovery was found to be 97.3%;and its coefficient of variation
was2.8%
