[Study on chemical constituents from Swertia kauitchensis Franch].
OBJECTIVE
To study the major chemical constituents from the whole herb of Swertia kauitchensis Franch.


METHODS
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).


RESULTS
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).


CONCLUSIONS
All compounds were isolated from Swertia kauitchensis Franch for the first time.
