简介
An investigation of the chemical components of the fermentation extract of two cultures of Amylosporus cf. graminicola and Amylosporus cf. campbelii from Cuba and Zimbabwe, respectively, led to the isolation of seven previously undescribed secondary metabolites for which we proposed the trivial names amylosporanes A–G (17) along with the known compounds orsellinic acid (11), colletorin D acid (12), colletorin B (13), colletochlorin B (14), and the β-lactam cyclo-(S-Pro-R-Leu) (15). Three additional compounds (810) previously unknown from a fungal source were also characterized for the first time, and two of them were assigned the trivial names amylosporanes H–I (89) while the other was identified as cannabigerorcinic acid (10). The structures of the isolated compounds were determined based on their high-resolution electrospray ionization mass spectrometry (HR-ESIMS) spectra and an extensive …
