摘要
[目的]建立降血脂保健饮料中总黄酮的测定方法.[方法]采用分光光度法,以芦丁为对照品,在波长为510 nm处测定总黄酮含量.[结果]芦丁在16.5-82.5μg之间线性关系良好,平均回收率为98.9%,RSD为2.29%.[结论]采用分光光度法测定轮叶党参降血脂保健饮料中总黄酮的含量简便易行,重复性好.
OBJECTIVE To establish the measurement method of cholesterol lowering health beverage. METHODS The content total of flavone of Codonopsis Lanceolata total flavone was detected by spectrophotometry, Rutin （Sophorin） as comparison measure under 510 nm. RESULTS The Rutin （Sophorin）＇ s line sexual behaviors at 16.5-82.5μg are good, and average recovery rate was 98.9 %, and RSD was 2.29 %. CONCLUSION The spectrophotometry was used in assaying total flavone of Codonopsis Lanceolata cholesterol lowering health beverage is easy, and has good repetition.
