Abstract Six kinds of plant pathogenic fungi，Pythium aphanidermatum，Phytophthora capsic，Fusarium oxysporium，Fusarium solani，Botrytis cinerea and Fusarium graminearum were used to measurate the antifungal activities of acetone extracts from 28 medical plants by mycelia growth method．Eugenia caryophyllata showed potent antifungal activity with 100% inhibitory rate against all tested plant pathogenic fungi，Armeniaca mume，Stemona sessilifolia，and Aucklandia lappa also possessed over 70% inhibitory activity against five of the six plant pathogenic fungi．The high active medical plants above were further studied by spore germination method，and the inhibition rates against Botrytis cinerea conidia were above 90%．
