摘要: 真菌ST026（Altemaria alternate var.monosporus）的发酵产物,经过常压正相硅胶柱，中压正相硅胶柱，中压反相ODS柱色谱和重结晶等4步纯化得紫杉醇（纯度99.0%），4步总收率0.003 9%（以发酵浸膏计），紫杉醇的回收率为38.5%。Abstract: Four steps,including normal silica gel chromatography,medium pressure silica gel chromatography,medium pressure ODS RP-chromatography and recrystalization,were used to isolate and purify paclitaxel from the fermented extracts of ST026 (Altemaria alternate var.monosporus).The total yield of paclitaxel was 0.003 9% with the purity of 99.0% and the recovery of of 38.5%.
