摘 要: 研究了紫外光分光光度法测定食品包装用功能性添加剂———灯心草黄酮苷含量的方法,以芦丁为参照品,测量波长为359 nm,平均回收率为100.01%,精密度为1.72%,说明紫外分光光度法是一种较理想的测定方法。 Total flavonoid content in Juncus effuses L. were determined by UV Spectrophotometry. The contrast sample of UV Spectrophotometry was rutin and the analyzed wavelength was 359 nm, the average recoverity is 100.01% and RSD is 1.72 %. By the results, it was found that UV Spectrophotometry was a fine method for detection of total flavonoid content in Juncuse effusus L..
