Abstract : The antifungal activity of acetone extracts of 72 Chinese herb species from 41 families against 9 pathogens (Colletotrichum musae, Fusarium semitectum [F. pallidoroseum], Verticillium theobromae, Cladosporium cladosporioides, Nigrospora oryzae [Khuskia oryzae], Colletotrichum gloeosporioides [Glomerella cingulata], Botryodiplodia theobromae, Alternaria alternata and Dothiorella dominicana) of postharvest diseases of banana and mango fruits was investigated. At 20 mg/ml, all the Chinese herb extracts had ability to inhibit the mycelial growth of the 9 pathogens, and the average inhibitory rate was 34.80%. The inhibitory rate of Eugenia aromatica [Syzygium aromaticum] reached 100%, while that of Cinnamomum cassia [C. aromaticum] and Illicium verum were above 90%. Sixteen Chinese herb acetone extracts showed more than 50% average inhibitory rates to the 9 pathogens. The different Chinese herbs had different antifungal abilities to the 9 pathogens. The EC50 values of E. aromatica, Cinnamomum cassia and I. verum to the 9 pathogens were only 0.38-13.47 mg/ml.
