Abstract
Three new pyrones, solanapyrones P–R (1–3), were afforded by the extracts of the endophytic fungus Alternaria tenuissima SP-07 isolated from the fresh root of Chinese herbal medicine Salvia przewalskii, along with the known solanapyrones (4–6) and benzopyrones (7–9). Solanapyrones P (1) and Q (2) possess an unprecedented nor-solanapyrone skeleton as natural products. Their structures were determined on the basis of NMR and HR-ESI-MS analysis. The plausible biosynthetic pathways to those unknown compounds were discussed. All the isolated compounds were evaluated for their antibacterial activities against six bacteria.
