Abstract：Objective To study the content of rutin in different period of mulberry leaf. Methods The Kromasil C18 column(4. 6 mm × 250 mm,5μm)was used,and mobile phase was composed of methanol-0. 5% phosphoric acid solution ( gradient elution),Detection wavelength was at 358 nm,the column temperature was at 30℃. Results The linear range of rutin was 0. 126 2~2. 02 μg( r=0. 999 9). The average recovery of rutin was 97. 88%,the highest content of rutin in mul-berry leaves before and after the frost. Conclusion Preliminary results suggested that rules of rutin in mulberry leaves sea-sonal changes.
