Two new quinazolinone alkaloids from .

Two new quinazolinone alkaloids, benzomalvin F (), and quinadoline C (), along with four known quinazolinones (-), were isolated from cultures of the wetland-soil-derived fungus from the Huixian wetland in Guilin. Their structures were elucidated based on detailed spectroscopic analysis, including 1D, 2D NMR, mass spectrometry, and IR spectra. In addition, the anti-inflammatory results showed that compounds , , , and had significant inhibitory effects on NO production in RAW264.

A new oleanane-type triterpenoid saponin with α-glucosidase inhibitory activity from .
