Abstract
Catharanthus roseus was extracted with methanol and its Vinblastine contents and antioxidant and antimicrobial activities in each methanol extracts were determined. Vinblastine contents of leaves were much higher than those in other plant parts. The highest DPPH(1,1-diphenyl-2 -picrylhydrazy) radical scavenging activities in plnat parts showed in leaves of Stardust Orchid and Cooler Rose and the value was $RC_{50}=17\;and\;18\;{\mu}g/ml$ respectively. Leaves of Cooler Rose and Coller Strawberry showed strong antimicrobial activities. Particularly, Cooler Rose showed strong antimicrobial activites except to Penicillium oxalicum.
