摘要
根据单因素试验法确定了黄麻链霉菌(Streptomyces corchorusii)NF0919菌株发酵产物的薄层色谱展开剂组分,利用均匀设计法和逐步回归法建立回归模型优化展开剂的配比,最终得出最优化的展开剂系统为氯仿一甲醇一水一冰醋酸=10∶2.75∶0.5∶0.2,分离效果较理想。
A strain of Streptomyces corchorusii （coded as NF0919） was isolated in our laboratory. It was antagonistic to Rhizoctonia solani Ktihn and produced atkyl glycoside which had antifungal activity. In this study, the TLC solvent system was developed to separate the chemical components of fermentation broth of Streptomyces corchorusii strain NF0919 based on single factor tests. The TLC solvent system was further optimized using the uniform design and quadratic polynomial stepwise regression. The optimal solvent system was determined to be：chloroform-methanol-water-glacial acetic acid = 10： 2.75： 0- 5： 0.2. Under the optimal solvent system ,the fermentation broth separated clearly.
