摘要
研究了从发酵液中提取泰乐菌素C的工艺条件,确定了甲苯为萃取溶剂,在pH9.25～10.02萃取3次,继而用乙酸乙酯在pH9.44条件下进一步萃取,30%酒石酸溶液反萃取至水相(pH3.88),得到纯度84%的酒石酸泰乐菌素C溶液。
A process for the extraction of tylosin C from fermentation broth was investigated and optimized. The filtrate was firstly extracted for three times using toluene at pH 9.25 - 10.02, and then the extracts were further extracted with ethyl acetate at pH 9.44. Tylosin C with the purity of 84 % was extracted again from ethyl acetate phase to water phase at pH 3.88 by 30% tartaric acid.
