摘要
以9种分别来自香蕉、杧果采后病害的病原菌[Colletotrichum musae(Berk.et Curt.)Arx、Fusarium semitectum Berk.et Rav.、Verticillium theobromae(Turc.)Mason & Hughes、Cladosporium cladosporioides(Fre.)De Varies、Nigrospora oryzae(Berk et Br.)Petch、Colletotrichum gloeosporioides Penz、Botryodiplodia theobromae Pat.、Alternaria alternate(Fr.)Keissl.和Dothiorella dominicana Petr.& Cif.]为供试菌种,在中草药质量浓度相当于20mg/mL干药材的条件下,测定了41科72种中草药丙酮提取物对菌丝体生长的抑制作用。结果表明,供试的所有中草药提取物均有不同程度的抑菌作用,平均抑菌率为34.80%,其中,丁香对9种病原菌的抑菌率为100%,肉桂和大茴香的抑菌率大于90%,平均抑菌率大于50%的中草药提取物有16种,同一中草药对不同病原菌及不同中草药对同一病原菌的抑菌活性均存在差异。平均抑菌率大于90%的丁香、肉桂和大茴香对9种病原菌的EC50值为0.38～13.47mg/mL。
The antifungal ability of Chinese herbal acetone extracts of 72 species from 41 families against 9 pathogens （Colletotrichum musae （Berk. et Curt.） Arx, Fusarium semitectum Berk. et Rav., Verticillium theobromae （Turc.） Mason ＆ Hughes, Cladasporium cladasporioides （Fre.） De Varies,Nigrospora oryzae （Berk et Br.） Petch,Colletotrichum gloeosporioides Penz ,Botryodiplodia theobromae Pat. ,A lternaria alternate （Fr.） Keissl. and Dothiorella dominicana Petr. ＆ Cif. ）of post-harvest diseases of banana and mango fruits were tested. The result showed that, at concentration of 20 mg dry Chinese herb per milliliter, all of them had ability to inhibit the mycelial growth of 9 pathogens, and the average inhibitory rate was 34.80%. The inhibitory rate of Eugenia aromatica Baillon reached 100%, while of Cinnamomum cassia Presl. and lllicium verum Hook. f were above 90%. 16 Chinese herbs acetone extracts showed more than 50% average inhibitory rates to 9 pathogens. The different Chinese herb had different antifungal ability to 9 pathogens. The EC50 values of E. aromatica, C. cassia and 1. Verum to 9 pathogens were only 0.38 mg/mL to 13.47 mg/mL.
