BACKGROUND
The antimicrobial property of has been tested against a variety of microorganisms in the literature. The present study aimed to assess the antimicrobial activity of different concentrations of commercially available powder against .
MATERIALS AND METHODS
An study was undertaken in which extract of was obtained using 100% ethanol by maceration. Seven different concentrations were prepared and tested against in brain-heart infusion agar medium. Plates were incubated aerobically at 37°C for 48 h, and zone of inhibition was measured using Vernier caliper. 0.2% chlorhexidine and dimethylformamide were used as positive and negative controls respectively. The data were analysed by descriptive analytic tests.
RESULTS
The maximum antibacterial activity of was observed with a volume of 40 μl at 2% concentration with a zone of inhibition of 19 mm. A 30 μl volume of 0.2% chlorhexidine showed a zone of inhibition of 28 mm, and no zone of inhibition was observed with dimethylformamide.
CONCLUSION
exhibited antimicrobial activity against . However, it needs to be confirmed further with studies.
背景
文献中已对[物质名称]的抗菌特性针对多种微生物进行了测试。本研究旨在评估市售[物质名称]粉末不同浓度对[目标微生物名称]的抗菌活性。
材料与方法
进行了一项[研究类型]研究，其中使用100%乙醇通过浸渍法获得[提取物名称]提取物。制备了七种不同浓度，并在脑心浸液琼脂培养基中针对[目标微生物名称]进行测试。平板在37°C需氧条件下孵育48小时，使用游标卡尺测量抑菌圈。分别使用0.2%洗必泰和二甲基甲酰胺作为阳性和阴性对照。数据通过描述性分析测试进行分析。
结果
在2%浓度下，40μl体积的[物质名称]观察到最大抗菌活性，抑菌圈为19mm。30μl体积的0.2%洗必泰显示抑菌圈为28mm，二甲基甲酰胺未观察到抑菌圈。
结论
[物质名称]对[目标微生物名称]表现出抗菌活性。然而，需要通过[研究类型]研究进一步证实。
