摘要
Objective To optimize the extraction technology of Taxus x media by using the contents of Paclitaxel and 10-deacetylbaccatin(10-DAB) ,two representative active diterpene alkaloids of taxane type from T.x media,as evaluation standard.Methods The smashing tissue extraction(STE) of Paclitaxel and 10-DAB from T.x media,was investigated by comparing with ultrasonic extraction(UE) which was one of the modern technologies of extraction.Results STE was more efficient than UE,and the contents of 10-DAB and Paclitaxel in the extracts obtained by STE were higher than those by UE.Conclusion STE is a fast,high-performance,and energy-saving technology for the extraction of diterpene alkaloids of taxane type.STE also provides a simple,component-safe,workable,and highly efficient method for the extraction of active natural product.
