【摘要】：黄芪药物资源的利用往往仅限于黄芪的根部,而黄芪茎、叶却被大量废弃,造成了药物资源的严重浪费。试验旨在采用益生菌发酵黄芪,研究黄芪根、茎、叶中黄酮类、皂苷类及黄芪多糖等有效成分含量的变化,以期高效利用黄芪。采用从鸡肠道分离保存的一株益生菌(FGM),用于发酵黄芪的根、茎、叶。结果显示,经FGM发酵后,黄芪根、一年生茎、两年生茎、一年生叶、两年生叶中粗多糖含量分别提高177.46%、227.27%、207.11%、170.61%、182.28%;总黄酮含量分别提高55.67%、33.68%、30.04%、-8.17%、-6.57%;总皂苷含量分别提高68.50%、55.91%、55.71%、40.93%、46.13%。以上结果表明,利用益生菌发酵可使黄芪各部位中主要活性成分含量提高,这对高效利用黄芪、进一步开发传统中药资源有非常重要的意义。
[Abstract]:The utilization of Astragalus drug resources is often limited to the roots of Astragalus, but the stems and leaves of Astragalus membranaceus are abandoned in large quantities, which results in a serious waste of drug resources. The aim of the experiment was to study the changes of flavonoids, saponins and astragalus polysaccharides in the roots, stems and leaves of Astragalus membranaceus by using probiotic fermentation of Astragalus membranaceus, in order to make efficient use of Astragalus membranaceus. A probiotic strain (FGM), isolated from chicken intestines was used to ferment the roots, stems and leaves of Astragalus membranaceus. The results showed that the content of crude polysaccharides in Astragalus root, annual stem, biennial stem, annual leaf and biennial leaf were increased by 177.460.27 and 207.11and 170.61and 182.28. the total flavonoids were increased by 55.6770.68-8.174- 6.57and the total saponins were increased by 68.5055.91and 55.71respectively. The results showed that the content of main active components in various parts of Astragalus membranaceus could be increased by using probiotic fermentation, which was of great significance for the efficient utilization of Astragalus and the further development of traditional Chinese medicine resources.
