Evaluation of Taxoids from Taxus sp. Crude Extracts by High Performance Liquid Chromatography

Abstract
The extraction procedures and analysis methods by high-performance liquid chromatography (HPLC) for taxine B (1), isotaxine B (2) and 10-deacetylbaccatin III (3), expected or already known “precursors” of paclitaxel or active analogues, were developed for in series analyses of Taxus needles.
