摘要：
An extract of the endophytic fungus Fusarium acuminatum (TC2-084) isolated from the Canadian medicinal plant Geum macrophyllum exhibited significant antimycobacterial activity against Mycobacterium tuberculosis H37Ra when fermented in both malt extract and potato dextrose broths. However, significant differences observed in the NMR spectra of the respective extracts led us to further investigate both. Bioassay guided fractionation revealed that lateropyrone was solely responsible for the bioactivity observed when TC2-084 was fermented in malt extract broth, while the antimycobacterial activity of the extract derived from the isolate fermented in potato dextrose broth was augmented by the presence of enniatins B, B1, and B4 in addition to lateropyrone.
