摘要:

研究了马尾松、湿地松、黑松松针的不同溶剂提取物对枯草杆菌、大肠杆菌、金黄色葡萄球菌、酵母菌、青霉、曲霉的抑菌作用,以及不同pH 值条件下松针粗提物的抑菌作用。结果表明,松针粗提物对供试菌有不同程度的抑菌作用,对枯草杆菌、曲霉的抑菌作用最明显。此外,三种松针的水提液、醇提液的抗菌活性具有较宽的pH 值范围(pH5~9)。

Abstract:

The antimicrobial effects of different extracts from Pinus massoniana Lamb, Pinus elliottii Engelm, Pinus thunbergii Parl with different solvents were investigated respetively. Result showed that all the pine needle crude extracts inhibit the growth of Escherichia coli, Bacillus subtilis, Staphylococcus aureus,Saccharorngces cerevisiae, Penicillium sp. and Aspergillus in different degrees. Especially, they have remarkable antimicrobial effects on Bacillus subtilis and Aspergillus. Furthermore, the antimicrobial activities of water and enthanol extracts of these three cultivars of pine needles have wider pH range (5 to 9).

Key words: pine needle, crude extract, antimicrobial effect
