精品文档---下载后可任意编辑五种中草药提取液对白灵菇深层发酵多糖的影响的开题报告摘要：本文旨在讨论五种中草药提取液对白灵菇深层发酵多糖的影响。采纳白灵菇菌丝体室内培育和深层发酵的方法，讨论了不同浓度的五种中草药提取液对白灵菇深层发酵多糖含量、多糖分子质量、糖链结构和免疫活性的影响，并比较了不同中草药提取液对白灵菇多糖的影响差异。结果表明，五种中草药提取液中，柴胡、党参和乌药提取液能提高白灵菇深层发酵多糖的含量和分子质量，且能够在一定程度上改变多糖的糖链结构和免疫活性；黄芪和天麻提取液对白灵菇深层发酵多糖的影响不明显。本讨论为利用中草药提取液提高白灵菇深层发酵多糖的含量和免疫活性提供了实验依据。关键词：白灵菇；深层发酵；多糖；中草药提取液；免疫活性Abstract：The purpose of this paper is to study the effects of five types of traditional Chinese medicine (TCM) extracts on the deep fermentation of polysaccharides from Tremella fuciformis. The polysaccharide content, molecular weight, glycosidic bond structure and immunomodulatory activity of the deep-fermented polysaccharides of Tremella fuciformis were studied under the influence of different concentrations of TCM extracts. Five different TCM extracts were tested and a significant difference in their influence on Tremella fuciformis polysaccharides was observed. The results showed that extracts of Bupleurum chinense, Codonopsis pilosula, and Lindera aggregata could improve the content and molecular weight of polysaccharides in Tremella fuciformis and partially alter the glycosidic bond structure and immunomodulatory activity of polysaccharides. However, the effects of extracts of Astragalus membranaceus and Gastrodia elata were not significant. This study provides experimental evidence for the use of TCM extracts to enhance the content and immunomodulatory activity of polysaccharides from Tremella fuciformis.Keywords:Tremella fuciformis; Deep fermentation; Polysaccharides; Traditional Chinese medicine extracts; Immunomodulatory activity
