The aim of this study is to isolate and identify the secondary metabolites of two special habitat actinomycetes, and explore their activity and medicinal value. Through preliminary screening, it was found that the fermentation broth of both actinomycetes had biological activity. Further substance separation and structural identification confirmed that one of the actinomycetes produced tetrahydroleft-handed ring pentanoyl hydrazine, and the other actinomycetes produced trimethyl ammonium bromide and 3-methylbutyric acid-1-methyl ester. In the future, the biological activity and medicinal properties of these products will be further studied.Keywords: Actinomycetes; Secondary Metabolites; Special Habitat; Substance Separation; Biological Activity正文：一、讨论背景放线菌是一类广泛存在于自然界的细菌，常常与土壤、水体等特别生境有紧密联系。放线菌具有丰富的次生代谢产物，许多具有药用价值的天然产物都是从放线菌中分离得到的。因此，从特别生境的放线菌中分离出活性物质，具有非常重要的药物开发和发现意义。本讨论旨在从两株特别生境放线菌中分离并鉴定其次级代谢产物，探究其活性和药用价值。精品文档---下载后可任意编辑二、讨论内容1. 两株特别生境放线菌的分离和纯化本讨论选定两个特别生境（分别为山顶和矿区），分别从这两个生境中分离出放线菌，并进行纯化和培育。2. 初步筛选和生物活...
