摘　　要：黄酮类化合物与铝盐形成配合物,该配合物在紫外可见光区有吸收,选择510nm为测定波长,芦丁作为对照品,用分光光度法测定芦笋中的总黄酮,平均回收率为97.23%,测定结果的相对标准偏差为2.13%(n=5)。The complex of Al(Ⅲ)-flavonoid has absorption in ultraviolet and visible region. Rutin as the control, the total flavonoid in asparagus officinalis Linn was determined by spectrophotometry with the detection wavelength of 510 nm, the average recovery was 97.23%, RSD was 2.13%(n=5).
