Abstract:

In order to explore the efficient and low contaminated extraction process of vindoline,catharanthine,vincristine and vinblastine from Catharanthus roseus,comprehensive optimization of condition in ultrasonic-methanol method were studied. On the basis of single factor experiments,orthogonal test was made,and the optimum parameters for obtaining vindoline and catharanthine were determined as follows: Methanol as solvent was used for 180 min,which pH value was 4.0. The ratio of raw material to solvent is 1:15 (w/v),the extraction temperature is 45 ℃,and extraction frequency is 59 KHz. The yield of vindoline and catharanthine in the conditions were 0.164% and 0.081%, respectively.
