摘要

本研究的目的是考察乙醇和乙酸乙酯提取液在10%、5%、2.5%和1.25%的浓度变化下，对不同病原菌大肠杆菌(ATCC 25922)和金黄色葡萄球菌(ATCC 25923)病原菌产生的抑制作用。方法采用圆盘白纸扩散法，以圆盘氯霉素为对照。在变异中，浓度为10%的结果最高。并将该浓度与对照进行比较，结果表明:茎皮乙醇和乙酸乙酯提取物对大肠杆菌和金黄色葡萄球菌的提取率分别为14.7和14.5;11.6和13.5。叶片:14.6和13.5;14:0和13:30

Antibacterial Activity of Extract Ethyl Acetate and Ethanol of Raru (Vatica pauciflora Blume)

This research purpose is to show the inhibition of the extract of ethanol and ethyl acetate stem bark and leaf of Raru according to the causes of bacterial E-coli (ATCC 25922) and St Aureus (ATCC 25923) with variation concentration 10%, 5%, 2.5% and 1.25%. Methods used were diffusion with disk blank paper and disk cloramphenicol as a control. The highest result observed on 10% concentration among the variation. This concentration then compared with control and the result as follow for stem bark of ethanol and ethyl acetate exctract for bacterial E-coli and St Aureus : 14.7 and 14.5 ; 11.6 and 13.5. for leaf : 14.6 and 13.5; 14.0 and 13.30
