鹅掌楸树叶和树皮提取物的抑菌活性研究
Anti-bacterial effects of extracts from the Liriodendron L. barks and leaves
摘要
Abstract
Forest plant is one of the important medicine resources. Liriodendron L. is not only an important timber pro⁃ductive genus with superior wood quality, but also an important traditional Chinese medicine. Here, we report the results of anti⁃bacterial activities of extracts from Liriodendron L. barks and leaves. Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus faecalis were test strains, and the anti⁃microbial activities of the extracts were de⁃termined by agar dilution methods. The results showed that the growth of Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus faecalis on agar were obviously inhibited by adding extracts from Liriodendron L. barks and leaves. The MIC of the barks extracts were 5.12, 0.64, 0.64 and 0.64 mg/mL, respectively, and the MIC of the leave extracts were 40.96, 2.56, 2.56 and 2.56 mg/mL, respectively. The anti⁃microbial activities of the extracts from the barks were more effective than that of the leaves extracts. However, the anti⁃microbial activities among species within the Liriodendron L. were not significant statistically.关键词
