摘要
比较分析不同分布区的枸杞(Lycium chinense)和宁夏枸杞(Lyciumbar barum)的幼嫩叶片的总黄酮和多糖含量差异。结果表明:在单个物种内,居群之间多糖含量和总黄酮含量都没有显著性差异;在这两个物种之间,枸杞和宁夏枸杞的总黄酮含量没有显著性差异;枸杞的多糖含量显著高于宁夏枸杞,因此枸杞叶片可能是更好的药用蔬菜和枸杞茶原料。在居群内,不同个体之间的总黄酮和多糖的含量差异极显著,因此在种内进行良种选育可能获得表现一致的优良品种。
Young leaves of L.bararum and L.chinense with different geographical origins were compared for differences in main active compounds,such as polysaccharides and total flavonoids.Among geographical populations of each species and between the two species,no significant differences in contents of polysaccharides and total flavonoids were seen,respectively.While the content of polysaccharides in young leaves of L.chinense were significantly higher than that of L.bararum.Hence,L.chinense leaves were a potential source for medicinal food.Science there were significant differences in contents of polysaccharides and total flavonoids within the same geographical population of each species,it is of great interest to develop good varieties by interstrain breeding.
