- Abstract
Spatholobus suberectus Dunn as a traditional Chinese herbal medicine, which is susceptible to being infected by molds during storage. In order to explore the diversity characteristics of fungal community and the quality evaluation of Spatholobus suberectus Dunn during the process of mildew. The study used high-throughput sequencing technology to detect the diversity characteristics of fungal community, high-performance liquid chromatography (HPLC) and ultraviolet spectrophotometry (UV-spectrophotometry) methods to detect the content of flavonoids, and enzyme-linked immunosorbent assay (ELISA) method to detect the content of Aflatoxins B1 (AFB1). The result showed that the fungi of all samples belonged to 14 phyla, 336 genera, and the dominant fungi at the early stage of mildew was not obvious, while that at middle and late stages of mildew was Aspergillus. The species diversity of fungal community was the highest at the early stage of mildew, while the species richness of fungal community was the highest at the late stage of mildew. The content of AFB1 showed an upward trend, while the content of flavonoids showed a downward trend during the process of mildew. In brief, the diversity of fungal community decreased gradually, and the number of dominant fungi increased gradually, and the quality of Spatholobus suberectus Dunn decreased gradually during the process of mildew. Key points: 1st key point: Explore the dominant fungi and the quality evaluation of Spatholobus suberectus Dunn during the process of mildew. 2nd key point: Dominant fungi are Aspergillus and the quality of Spatholobus suberectus decreased gradually. 3rd key point: Provide the theoretical basis for the development of new anti-molding technology.
