兩種鐵線蕨屬植物的粗抽取物和抽取的phenols之抗真菌活性

Antifungal Activity of the Crude Extracts and Extracted Phenols from Gametophytes and Sporophytes of Two Species of Adiantum

蕨類植物鐵線蕨（Adiantum capillus-veneris）和半月鐵線蕨（Adiantum lunulatum Burm. f.）的配子體和孢子體之水抽取物與抽出之phenols，在印度、中國、西藏、美洲、菲律賓和義大利被當作民俗藥物。本篇以此為材料，研究其對黑曲霉（Aspergillus niger）和葡枝根霉（Rhizopus stolonifer）的抗菌活性。發現兩者都有抗真菌活性，配子體之抽取物要比孢子體各部位的抽取物之抗菌活性大，在孢子體中則以未成熟的小孢子葉（pinnule）具有最大的抑真菌性能。比較兩種鐵線蕨植物，Adiantum capillus-veneris為較佳的抗真菌劑。

The water extracts and extracted phenols from gametophytes and different parts of sporophytes of the two ferns, Adiantum capillus-veneris L. and Adiantum lunulatum Burm. f., used as folkloric medicines in India, China, Tibet, America, Philippines and Italy, were investigated for their antifungal activity against Aspergillus niger and Rhizopus stolonifer. Both crude extracts and extracted phenols of gametophytes and different parts of sporophytes of both fern species were found to be bioactive against the fungal strains. Antifungal activity was found to be higher in gametophytes than different parts of sporophytes. Among the different parts of sporophyte, immature pinnule possesses highest fungistatic property. Adiantum capillus-veneris was found a better antifungal agent than Adiantum lunulatum.
