红果龙葵水提液与乙醇提取液的抑菌作用

Antibacterial Activity of Water and Ethanol Extracts from Solanum alatum Moench.Fruits

使用无菌蒸馏水和70%乙醇从红果龙葵果实中提取活性成分并探讨其抑菌作用。结果表明,提取物对微生物有明显的抑制作用。水提液的最低抑菌质量浓度分别为大肠杆菌2mg/mL、金黄色葡萄球菌1mg/mL、枯草杆菌0.5mg/mL、短小芽孢杆菌3mg/mL、产气芽孢杆菌0.5mg/mL;乙醇提取液的最低抑菌质量浓度分别为大肠杆菌2mg/mL、金黄色葡萄球菌2mg/mL、枯草杆菌1mg/mL、短小芽孢杆菌5mg/mL、产气芽孢杆菌1mg/mL。

To assess the antibacterial potency of Solanum alatum Moench.fruits,the water and ethanol extracts from Solanum alatum Moench.fruits were examined for their antibacterial activity against five common bacteria.It was found that both extracts had a notable inhibitory effect against the growth of all the bacteria tested.The minimum inhibitory concentrations of the water extract against Escherichia coli,Staphylococcus aureus,Bacillus subtilis,Bacillus pumilus and Enterobacter aerogenes were 2,1,0.5,3 mg/mL and 0.5 mg/mL,and those of the ethanol extract were 2,2,1,5 mg/mL and 1 mg/mL,respectively.
