Three new pterosins from .

Three new pterosins, named as semipterosin A (), B () and C (), together with 11 known pterosins (-), were isolated from the aerial parts of . Their structures were elucidated by HRESI-MS, NMR spectral data, CD and literature comparisons. Three new pterosins were assessed for their anti-inflammatory activity.

Three new flavonoid glycosides isolated from .

Three new flavonoid glycosides, ()-4',6,8-trihydroxyflavanone-7--glucoside (), ()-4',6,8- trihydroxyflavanone-7--glucoside () and distenin-7---D-glucoside (), along with nine known flavonoids (-) were isolated from the aerial of . Their structures were elucidated by the analysis of spectroscopy data and their comparison with the reported values. The two C-glycosyl flavanones ( and ), were isolated from this specie, which might be chemotaxonomic markers of this specie.
