The chemical investigation of ethanolic extract from Swertia mussotii Franch. has resulted in the isolation of 11 compounds which were identified as Orcinol-β-D-glucoside (1), Shamimin (2), Mangiferin (3), Decussatin (4), Bellidifolin (5), Desmethylbellidifolin (6), Protocatechuic acid (7), 1,7-Dihydroxy-3,8-dimethoxyxanthone (8), 1,8-Dihydroxy-3,5-dimethoxyxanthone (9), 1-Hydroxy-3,5-dimethoxyxanthone (10), Telephioidin (11). The chemical structures of these compounds were identified by a combination of spectroscopic analysis and a comparison with those reported in literature. Among them, compounds 1, 2, 7 and 11 were isolated from the genus Swertia for the first time. Moreover, the chemotaxonomic significance of these compounds was summarised. The chemotaxonomic study suggests that there is a close chemotaxonomic relationship between S. mussotii and other species of Swertia, such as S. punicea, S. macrosperma, S. japonica, S. phragmitiphylla, S. chirayita, S. cordata and S. binchuanensis, with presence of compounds 3~6, 8~10. The xanthones and their glycosides may sever as important chemotaxonomic markers of Swertia genus.

Separation of polar compounds especially with similar polarities is challenging. In the present study, three polar compounds with similar polarities, including gentiopicroside, sweroside and mangiferin, have been successfully separated from Swertia mussotii by a combination of two counter-current chromatography modes. With the selected solvent system of ethyl acetate/n-butanol/water (8/2/10, v/v), a continuous injection mode was firstly employed.

Cholestasis refers to a physiological and pathological process caused by bile acid (BA) overaccumulation inside the circulatory system and liver, leading to systemic and hepatocellular damage. Activating the farnesol X receptor (FXR) to restore BA homeostasis is a promising strategy for treating cholestasis. The objective of this research is to reveal solid evidence for the fact that the total iridoid glycosides from Franch.

is the most authentic raw material used in Tibetan medicine in China for its various bioactivities. This natural medicine resource is at risk of being exhausted due to the double interference of climate change and anthropogenic over-collection. Little is known about habitat characteristics and the crucial environmental factors that influence the levels of active ingredients.
