    Two new xanthones from Swertia angustifolia.[Pubmed: 22296155 ]
    Two new xanthones, angustin A and Angustin 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.
