| Abstract: | Taking rutin as standard sample,the content of flavonoids in citrus peels was measured with UV spectrophotometry at 261nm.The result shows:there was good linear relationship between the absorbance and concentration of the ruin.The correfficient was 0.9998,the average recovery rate was 99.79%,and RSD was 1.72%.The content of flavonoids in citrus Peels is about 0.857% this method is easy,rapid and the result is accurate. |
