From the fermentation extract of Xylarialean sp. A45, an endophytic fungus of Annona squamosa L., three new triterpenes, namely xylariacins A-C (1-3, resp.) were obtained. Their structures were determined by spectroscopic analyses, including 1D- and 2D-NMR experiments and HR-ESI-Q-TOF mass spectrometry. The in vitro cytotoxic activities of compounds 1-3 were tested against human tumor cell line HepG2, and these compounds showed modest cytotoxic activity.
