Abstract:
OBJECTIVE:To establish a quantitative analysis method to determine the contents of 1-deoxynojirimycin in mulberry resources such as Morus alba,Excrementum bombycis,Folium mori.METHODS:1-deoxynojirimycin in mulberry resources were determined by RP-HPLC method and UV detector on Hypersil C18(250 mm?4.6 mm,5 ?m)column, using acetonitrile-0.1% glacial acetic acid(50 ∶ 50)as moble phase. The flow rate was 1.0 mL?min-1 and the detection wavelength were set at 265 nm with column temperature at 35 ℃. RESULTS:The linear range of 1-deoxynojirimycin were from 5.0?10-4 mg?mL-1 to 1.0?10-3 mg?mL-1 (r=0.999 9)with recoveries of 97.7%(RSD=2.0%,n=6).CONCLUSION:The method is simple, accurate and reproducible for the quality control of Mulberry resources.
