食品包装用功能性添加剂灯心草黄酮含量测定的研究
Studies on the Determination of Flavonoid in Juncus Effuses L.
【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。
【Abstract】 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..
