摘要/Abstract

摘要： 以20种药用蕨类植物提取液对金黄色葡萄球菌、大肠杆菌、八叠球菌、变形杆菌、枯草杆菌、酵母菌进行抑菌活性研究,结果表明,20种蕨类提取液至少对一种供试微生物具有抑菌活性。样品蕨类醇提液比水提液具更强的抑菌活性,供试菌有阳性结果的水提液,平均抑菌圈直径10.12mm,而醇提液则为11.92mm。试验结果还表明,药用蕨类对枯草杆菌抗菌活性效果最明显,对酵母菌效果最差。不同蕨类植物其地上部分和地下部分抑菌效果不尽相同。

Abstract: The water extracts (PWE) and alcohol extracts(PAE) from 20 species of medicinal pteridophytes from Quanzhou were used for study the bacteriostatic activities on Staphylococus aureus, Escherichia coli, Sarcina lutea, Proteus species, Bacillus subtilis and Saccharomyces cerevisiae. The results showed that each extract from 20 medicinal pteridophytes had bacteriostatic activity against at least one tested microorganism. The bacteriostatic activity of PAE were more effective compared to that of PWE, and the average diameters of the inhibition zone of PWE and PAE were 10.12mm and 11.92mm, respectively. The bacteriostatic activity of pteidophyte against B. subtilis was the highest and against S.cerevisiae was the lowest. The differences of bacteriostatic activitgies between the aerial part and the underground part of the ferns varied with different species.

Key words: medicinal pteridophytes, water extract, alcohol extract, bacteriostatic activity
