摘要
目的:对7种受赭曲霉毒素A污染的根类药材进行污染真菌的分析,了解可能引起这些药材毒素污染的主要真菌类群。方法:用单孢分离法挑取药材表面的污染真菌,根据形态学及DNA序列特征对真菌进行鉴定。结果:从7份根类药材样品分离到6属17种真菌,其中青霉属真菌为主要污染真菌,有9个种,镰刀菌属3个种,曲霉属2个种,其他属3个种。结论:根类药材的真菌污染情况亟需重视,赭曲霉毒素A产生菌在药材上的分布具有一定的特异性。
Objective： To determine the fungal populations in seven ochratoxin A contaminated root herbs in Jiangxi province,and investigate the mycoflora associated with mycotoxin contamination in the root herbs.Method： Single spore isolation was used to obtain the strains from root herb′s surface.Fungi were identified according to morphology and molecular evidence.Result： Seventeen fungal species belonged to six isolated genera,nine species of Penicillium,three species of Aspergillus,two species of Fusarium and three other species were identified.Conclusion： Fungal contamination of root herbs demands urgent attention,ochratoxin A producing fungi possess specific distribution on herbs.
