Abstract

The content of vindoline, catharanthine and vinblastine in the root, stem, leaf, flower and fruit of Catharanthus roseus at various developmental stages were determined, and the biomass allocation was also determined to find the best harvest time.The content of vindoline, catharanthine and vinblastine in the root, stem, leaf, flower and fruit of C. roseus were determined by HPLC.The content of these alkaloids were influenced by season and it varied in the different tissues of the plant. The content of vindoline and catharanthine in the leaves were the highest, and there was no vindoline detected in the root, but the content of vinblastine in the flower was the highest; the content of vindoline and catharanthine reached the maximum between the August and September, and the content of vinblastine reached the highest after the September. The biomass was the highest in the initial stage of September.The best harvest time was in the initial stage of September.
