摘要
目的研究腊梅花黄酮苷含量。方法采用紫外光分光光度法测定不同产地的腊梅花黄酮苷含量,以芦丁为参照品,测量波长为359nm。结果均回收率为100.03%,精密度为1.44%。结论紫外分光光度法测定不同产地的腊梅花黄酮苷含量是一种较理想的测定方法。
Total flavonoid content of Chimonanthus praecox of different places was determined by UV spectrophotometry. The contrast sample was rutin and the analyzed wavelength was 359 nm, the average recovery was 100.03% and RSD was 1.44%. By the results, it was found that UV spectrophotometry was a fine method for detection of total flavonoid content in Chimonanthus praecox.
