摘要
采用薄层分离和荧光光度法对芦荟中芦荟甙的含量进行了测定，在硼砂介质中，芦荟甙与硼砂发生化学反应，使体系荧光强度提高了10倍．方法的检测限为2．0×10－9mol·L－1．灵敏度高，重现性好．用标准加入法测定2种样品，回收率在92．9％-104．0％之间．
The thin - chromatographic separation and flurimetric determination of barbaloin in Aloe vera is described. When the barbaloin reacts with borax, the system fluorescence intensity is 10 times that of origin. This method is sensitive and reappearance. Its detection limit is 2.0 × 10 -9 mol· L-1. It can be applied to the determination of barbaloin in Aloe vera and raw glue. The recoverry ratio of measurement is 92.9% ~ 104.0%.
