Abstract

Abstract: The content of CPTand VCS-LTcould be improved to 4.88%, 21.52%, respectively from 0.379%, 1.524% in crude extract solution after refined by X-5 resin.Then the refined solution was chromatographically separated with hypercrosslinked resin and the contents of VCS-LTcould be improved to about 60%(CPT15%).The achromaticity needle crystal was obtained after several recrystallization and its structure was confirmed by IR, ¹HNMR, ¹³CNMR, MSand element analysis.

Key words: Adsorptive resin, Vincoside-lactam, Layer chromatographic separation
