Abstract

Quinidine a compound isolated from quinine plants, one of the species of quinine plants is (Chincona ledgereriana) From PT SIL Lembang. The purpose of this study was obtain quinidine salicylate ester through esterification reaction. In this study, the synthesis of quinidine ester compound by esterification reaction was conducted. Esterification reaction was conducted by using DCC activator and DMAP catalyst with one carboxylic acid namely salicylate acid producing new compound namely quinidine salicylate, Subsequent Quinidine salicylate was obtained in the form of oil with 97% yield. The compound obtained from the synthesis was then identified using Thin Layer Chromatography continue analyzed using with Spectrophotometer, LC-ESI-MS spectroscopy. Results show that the target compound has been successfully synthesized.

Abstract

The purpose of this research is to identify the chemical content and compare the antibacterial effect of Piper betle L and Piper crocatum R oil against Streptococcus mutan. Betel oil is made at 100%, 75%, 50%, 25% concentration and amoxicillin 0.2% as positive control and propylene glycol as negative control. The research method started with oil isolation using distillation of steam and water then identified the content using GC-MS. Antibacterial activity was tested against Streptococcus mutans by disc diffusion method. The results of this research indicate that Piper betle L and Piper crocatum R oil contains terpenoid group compounds. After being characterized using GC-MS, betel oil contains 5 major active compounds that have antibacterial activity that is Sabinene, Myrsene, Camphene, Germacrene and β - Chariophillene. Piper betle oil has better antibacterial properties than Piper crocatum oil with clear zone reaches 10.5 mm while Piper crocatum oil is 7.1 mm.
