ABSTRACT
Objective To investigate the characteristics of growth, accumulation of indole alkaloid, and the optical concentration of the nutrition components in the Catharanthus roseus mutant cells induced by the colchicine, looking forward to getting the ideal material producing alkaloids which was suited for industrialized cell cultivation. Methods Mutant cells cultivated on the MS medium were harvested according to experiment designs,and the fresh weight was got.The indole alkaloid as extracted by organic solvent. The ajmalicine and catharanthine extracted from the samples were analyzed by RP-HPLC. Results The growth rate was faster and the indole alkaloid accumulation was more when the mutant cells were cultivated generations 30 and the both were sharply decreased at generations 45, while the contents of medical compounds amounted to the peak at the generations 20. The content of medical components and alkaloid accumulation were evidently prompted by the tryptophan added in the media, especially at the concentration of Ca2+ 1 760 and Zn2+ 12.6 mg/L, respectively. Conclusion C.roseus mutant cells probably is an ideal material for industrialized cell cultivation.
