- Abstract
Objective: To examine the antifungal effect of different extract of Dryopteris fragrans (L.) Schott. in vitro, and screen the effective fraction from those extracts., Methods: Separated the Dryopteris fragrans extract and got four parts by refluxing extraction,and determined the contents of total phloroglucinol. Disc agar diffusion method and solid agar dilution method were used to determine inhibitory effect. Minimum inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) of different parts of Dryopteris fragrans extract against four strains of common clinical dermatophytes were investigated., Results: The data showed that the contents sequence of total phloroglucinol was in the following order: 95% -ethanol extract > water extract > diethyl ether extract > petroleum ether extract, and the antimicrobial activities against the four dermatophytes were as following order: 95% -ethanol extract > water extract > di-ethyl ether extract > petroleum ether extract., Conclusion: The contents of total phloroglucinol in 95% -ethanol extract of Dryopteris fragrans is the highest, and the antifungal activity against dermatophytes in vitro is the strongest. The effective fraction of Dryopteris fragrans is the 95%-ethanol extract.
