摘要
本实验分别用水和70%乙醇从榅桲中提取其活性成分黄酮,测试其抑菌作用。结果表明,榅桲提取物对微生物有不同程度的抑制作用。5种受试菌中,铜绿假单胞菌对样品的抗菌活性较为敏感,榅桲的醇提液比水提液具有更明显的抑菌效果。这将为榅桲开发为新型抗菌药物提供一定的理论依据。
This experiment studied on antimicrobial characteristics of flavone extract from Cydonia oblonga Mill with water or 70% ethanol.The results showed that flavone extracts could inhibit the growth of bacteria.Among the five bacteria tested,the best antibacterial effect was against Pseudomonas aeruginosa.Ethanol extracts had better antibacterial effects than water extracts.It is believed that Cydonia oblonga Mill could be developed into a new type of antimicrobial drugs in the future.
