安康市部分桑树栽培品种桑叶1-脱氧野尻霉素含量的测定

摘要

为促进蚕桑产业的发展,促进桑叶产品的开发,以安康地区具有代表性的24个桑树栽培品种的桑叶为原材料,运用反相高效液相色潽法测定各品种春季桑叶中1-脱氧野尻霉素(DNJ)的含量.结果表明,安康地区桑树品种中桑叶DNJ含量具有显著差异,其中旬阳青皮荆桑中的含量最高为0.381 5%,显著高于其他品种;大坪2号变异、恒2号、安选1号、流水青桑、当地胡桑、沈2号、大坪桐桑、箔篮桑、前进桑含量较高;而光明桑、荆桑12号等品种含量较低.旬阳青皮荆桑DNJ含量最高,可以作为DNJ提取的桑树品种.%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 sig-nificant differences. The content of DNJ in leaves of Xunyangqingjing is 0.3815%,it is significantly higher than the other va-rieties. 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 con-tent of DNJ.
