Abstract

Abstract. Dental caries is a disease with a high prevalence of caries in Indonesia is caused by the bacterium Streptococcus mutans. The leaves of the soursop (Annona muricata Linn.) is one of the herbs that can remove dental plaque. This study aims to determine the chemical content and measure the inhibitory antibacterial soursop leaft methanol extractin inhibiting the growth of Streptococcus mutans bacteria. Phytochemical screening stated that the leaf of the soursop contains flavonoids, alkaloids, tannins, steroids, glycosides and saponins. Test of inhibition were measured using paper disc diffusion method with variation concentrations of 5, 10, 15 20, and 25%, positive control is tetrasilkin 30 µg, and a negative control is methanol. Antibacterial test results showed that the methanol extract of soursop leaves have antibacterial activity against Streptococcus mutans at concentrations of 5, 10, 15, 20 and 25% with inhibitory diameter of 9,1; 10,57; 11,53; 12,01 and 13,75 mm respectively. Keywords: Soursop leaves, Dental caries, Streptococcus mutans, Methanol.*Judul ini telah dipresentasikan pada Seminar Nasional: Indonesian Students Conference on Science and Mathematics (ISCSM) 11-12 November 2015, Banda Aceh Indonesia

Abstract

N-hexane extracts of the bark from black plum(Syzygium cumini (L.) Skeels) showed activity againtSalmonella typhi. Meanwhile,  the result showed that N-hexane was not able to inhibit the  growth of Candida sp. The research was done at Microbiology laboratory, Biology Department Faculty of Mathemathics andScience,  Syiah Kuala University. The bark of black plum were collected from Aceh Besar District. The extraction method  for black plum used maceration with N-hexane and than concentrated in rotary evaporator. The disc diffusion method used to screen the antimicrobial activity with 20 %, 30 %, 40 % dan 50 % concentration.
