Plants of the genus Swertia (Gentianaceae) comprise about 170 species, of which 79 are present in China . Swertia is a popular medicinal herb, which has been used for the treatment of dyspepsia, urinary infection, and hepatitis diseases in the middle-western ethnic district of China . Iridoids, secoiridoids, xanthones, flavonoids, and triterpenoids have been proved to be the main constituents of the genus Swertia . Swertia bimaculata Hook.f. & Thomson ex C.B. Clarke is a well-known ethnomedicine recorded as Zhangyacai in Jiuhuang Bencao composed of the Chinese Ming Dynasty 600 years ago . Besides the report of several xanthones and oleanolic triterpenes from this species, the chemical composition of S. bimaculata is still unexplored . Therefore, we have performed a phytochemical investigation into the whole plants of S. bimaculata.
