J Asian Nat Prod Res. 2012;14(2):154-8. doi: 10.1080/10286020.2011.641013.

Abstract

Two new xanthones, angustins A and B (1 and 2), were isolated from the aerial parts of Swertia angustifolia together with six known compounds (3-8). The structures of these two xanthones were elucidated by extensive analysis of the spectroscopic data. In addition, compounds 3 and 6-8 were isolated from this plant for the first time.
