Abstract

Abstract: The contents of 1-deoxynojirimycin （DNJ） in spring leaves from 24 representative cultivars of mulberry in Ankang city were determinated using reversed-phase high performance liquid for promoting the development of sericulture industry and the development of mulberry products. The results indicate that the contents of DNJ in different mulberry cultivars have significant differences. The content of DNJ in leaves of Xunyangqingjing is 0.3815%,it is significantly higher than the other varieties. The contents of DNJ in leaves of Daping No. 2 variation,Heng No. 2,Anxuan No. 1, Liushuiqingsang, Local husang,Shen No. 2,Dapingtongsang,Bolansang, Qianjinsang are relatively high; the contents of DNJ in leaves of Guangmingsang,Jingsang are relatively low. The variety of Xunyangqingjing could be as material for exaction DNJ because of the highest content of DNJ.

Key words: 1-deoxynojirimycin, mulberry leaf, reversed-phase high performance liquid chromatography, Ankang city
