14种高原植物抑制植物病原菌活性的初步研究
Antimicrobial activity of the extracts of fourteen plants from the Qinghai-Tibet plateau against phytopathogen
摘要
Abstract
Fourteen plants, belonging to 11 families from the Qinghai-Tibet plateau of China,were extracted with 95 ％ ethanol.The extracts were evaluated antifungal activity against six plant pathogenic fungi used the mycelial growth inhibition assay in vitro.At the concentration of 1 mg/mL,the extracts from A.sinica Hance.,C.connata,A, gymnandrum showed the obvious inhibitory action against the fungi V.ceratosperma by 77.10％、68.14％、67.53％;the extracts from A.sinica Hance.,A.gymnandrum, P.fruticosa L.,M.cochinchinensis also showed high inhibitory against C.gloeosporivides with the inhibitory of 81.02％ 、66.53％ 、62.10％、61.34％.Through the further study on the different solvent extractions of the ethanol extract from A.sinica Hance., the results indicated that the effective inhibitory components were included in the n-hexane extract.关键词
