Two new flavanones from Hedw.

Seven flavanones, including two new compounds coupled with styryl units, communins C () and D (), as well as five known compounds, were isolated from Hedw. The planar structures of all compounds were determined using extensive spectroscopic analysis. The absolute configurations of two new compounds were assigned by comparing experimental ECD with calculated ECD.

detection and mass spectrometry imaging of protein-related metabolites in Bombyx batryticatus before and after frying with wheat bran.

Bombyx batryticatus is derived from the dried larva of Linnaeus infected by (Bals.) Vuillant. Raw Bombyx batryticatus should be stir-fried before oral administration due to its irritation to the gastrointestinal tract.

Two new benzophenones from the moss .

Two new benzophenone derivatives ( and ), named Pogonatone and pogonatone , were isolated from the moss . Their structures were elucidated by spectroscopic data analyses. The cytotoxicity of compounds for HepG2, HCT-116, A-549 and PANC-1 cells line was also evaluated by using the MTT method.
