Aktivitas Antimikroba Ekstrak Etanol Daun dan Bunga Tahi Ayam (Tagetes erecta Linn.) terhadap Pertumbuhan Streptococcus mutans, Shigella dysenteriae dan Candida albicans secara in Vitro

Abstract

In vitro antimicrobial activity of ethanol leaves and flower extract of tahi ayam (Tagetes erecta Linn.) against growth of Streptococcus mutans, Shigella dysenteriae and Candida albicans has done. The purpose is to study the component secondary metabolites of the extracts and to investigate the ability of the plant extract against the growth of S. mutans, S. dysenteriae and C. albicans. Both leaves and flower extract used were 0, 5, 10, 20 and 40%. The extract was made by maseration method and the activity antimicrobial was conducted by disc diffusion. The result showed that secondary metabolites of tahi ayam leaves are alkaloid, steroid and terpenoid while the flowers are alkaloid, flavonoid, steroid, terpenoid and saponin. Ethanol leaves and flower extract has a difference in inhibiting S. mutans, S. dysenteriae and C. albicans. In 5% ethanol extract of leaves and flower inhibits the growth of S. mutans, S. dysenteriae and C. albicans. Minimum inhibition concentration ethanol leaves and flower extract against S. mutans, S. dysenteriae and C. albicans are 1%.
