Plant extracts are used in folklore medicine from time immemorial to treat different oral diseases. Chemical constituents extracted from these natural resources are gifted with huge opportunities.
The aim of this study is to assess the antibacterial property of (Neem), (Tulsi), and (Pochotia) against oral microorganisms.
Plant extract was prepared with hot continuous extraction method by the Soxhlet Apparatus. Microorganisms isolated from the oral cavity and identified by Vitek-2. Bacterial inoculums poured and spread into Mueller Hinton plates. Plant extract was poured into prepared wells taking ciprofloxacillin as the positive control and dimethyl sulfoxide as the negative control. The experiment was performed in duplicates with two different concentrations of the extract and mean value of inhibition zone was calculated.
Paired -test, analysis of variance, and regression analysis.
Isolated microorganisms were , and . Higher zone of inhibition was observed against by followed by . Among the aqueous and acetone group, in the aqueous group, the regression models of and have been found to be statistically significant (= < 0.05), whereas, in the acetone group, the regression model of has been found to be statistically significant ( = < 0.05).
All the three plants showed antibacterial potency against the isolated organisms. Acetone group showed better efficacy than the aqueous extract group.
自古以来,植物提取物就被用于民间医学治疗各种口腔疾病。从这些自然资源中提取的化学成分具有巨大的应用潜力。
本研究旨在评估印楝、罗勒和波乔蒂亚对口腔微生物的抗菌性能。
采用索氏提取器通过热连续提取法制备植物提取物。从口腔分离微生物并通过Vitek-2进行鉴定。将细菌接种物倾注并铺展到穆勒-欣顿平板上。以环丙沙星为阳性对照,二甲基亚砜为阴性对照,将植物提取物倾注到制备好的孔中。用两种不同浓度的提取物重复进行实验,并计算抑菌圈的平均值。
配对t检验、方差分析和回归分析。
分离出的微生物为变形链球菌、白色念珠菌和牙龈卟啉单胞菌。印楝对变形链球菌的抑菌圈最大,其次是罗勒。在水提取物组和丙酮提取物组中,在水提取物组中,印楝和罗勒的回归模型具有统计学意义(P = < 0.05),而在丙酮提取物组中,印楝的回归模型具有统计学意义(P = < 0.05)。
这三种植物对分离出的微生物均显示出抗菌效力。丙酮提取物组比水提取物组显示出更好的效果。
