摘要/Abstract

摘要： 本试验研究用薄层扫描法测定肾茶中熊果酸含量。样品经适当提取后点于硅胶GF254薄层板上,以环已烷-氯仿-乙酸乙酯-甲醇(25:15:5:2)为展开剂,置于紫外光灯(波长254nm)下定位;双波长反射锯齿扫描,λ_S=520nm,λ_R=650nm。结果表明,经方法学考察,点样量在0.5~2.5μg范围内呈现良好的线性关系,其回归方程为y=3658.34X-7857.07,r=0.9998;平均回收率为101.57%,RSD=2.83%。

Abstract: A TLCS method for determining the content of ursolic acid in Clerodendranthus spicatus was established in this experiment. The method was as follows. After extraction, the samples were dripped on silica gel GF254 TLC plate, using a mixture of the alkane-chloroform-acetic acid B ester-methyl alcohol (25:15:5:2) as developer and locating the position under the light of an UV lamp(254nm); double wavelength reflection sawtoothed scanning was performed λ_S=520nm, λ_R=650nm. The results showed that the regression equation is y=3658.34 X-7857.07, r=0.9998 and linear range is 0.5~2.5μg. The average recovery rate is 101.57%, RSD=2.83%.

Key words: Clerodendranthus spicatus, ursolic acid, TLC method, content measurement
