野牡丹属植物对大肠杆菌的抑菌效果
Study on Bacteriostatic of Melastoma on Escherichia coli
摘要
Abstract
Melastoma affine was used as test material and the aspetic water was as extractant.The antibacterial activity of Melastoma affine leaves to Escherichia coli was studied by disc diffusion method ,An orthogonal test which includes water bath time ,water bath temperature,and ratio of solid to liquid at three different levels was used to determine the optimum extractive condition of antifungal substance of Melastoma leaves.The results showed that the optimum extractive conditions was leaching-temperature 60 ℃,extracting time 2h,ratio of solid to liquid 1∶30.Under the optimum extractive condition ,the antibacterial activity of parts of Melastoma L.leav-es were compared , the result showed the ability of bacteriostatic was M.sanguineum >M.dendrisetosum >M.intermedium >M.affine.关键词
