THE ANTIMICROBIAL EFFECT OF GENUS VINCA ON SOME PATHOGEN MICROORGANISM

Abstract

Vinca major, minor and rosea are three species of vinca genus and Apocynaceae family. The present work is to investigate antimicrobial effects of these plants against Candida albicans, Pseudomonas aeroginosa and Staphylococus aureus. Alkaloids from leaf extracts had a better effect on pseudomonas aeroginosa than alkoloids from stem and root. Alkaloids from stem extracts were more effective than alkaloids from other parts on Staphylococus aureus. Root alkaloids were more effective on C. albicans. The antimicrobial effect of vinca minor was the most.
