[Chemical constituents from petroleum ether fraction of Swertia chirayita and their activities in vitro].
The present work is to study the chemical constituents from petroleum ether fraction of Tibetan medicine Swertia chirayita by column chromatography and recrystallization. The structures were identified by physical and chemical properties and spectral data as swerchirin (1), decussatin (2), 1,8-dihydroxy-3,5,7-trimethoxyxanthone (3), 1-hydroxy-3,5,7,8-tetramethoxyxanthone (4), bellidifolin (5), 1-hydroxy-3, 7-dimethoxyxanthone (6), methylswertianin (7), 1-hydroxy-3,5-dimethoxyxanthone (8), erythrodiol (9), oleanolic acid (10), gnetiolactone (11), scopoletin (12), sinapaldehyde (13), syringaldehyde (14), and β-sitosterol (15). Compounds 3, 4, 9, 11-14 were isolated from S. chirayita for the first time. Compounds 9 and 12 were firstly isolated from the genus Swertia. The cytotoxic activities of compounds 1, 2, 5, 7 and 8 against human pancreatic cancer cell lines SW1990 and BxPC-3,and the protective effects of these compounds against hydrogen peroxide (H2O2)-induced oxidative stress in human endothelium-derived EA.hy926 were investigated in vitro. The results showed no obvious effect at the high concentration of 50 μmol•L⁻¹.

[Study on chemical constituents from Swertia kauitchensis Franch].
To study the major chemical constituents from the whole herb of Swertia kauitchensis Franch.. Compounds were separated and purified with silica gel column and microreticular resin, and their structures were elucidated on the basis of spectroscopic evidence (UV, IR, MS, NMR).. Ten compounds were identified as oleanolic acid (1), beta-sitosterol (2), daucosterol (3), gentiacaulein (4), bellidifolin (5), methylswertianin (6), swertianin (7), 1,7-dihydroxy-3,4,8-trimethoxyxanthone (8), swertianolin (9),1,3,5,8-tetrahydroxyxanthone (10).. All compounds were isolated from Swertia kauitchensis Franch for the first time.
