[Chemical constituents from herbs of Swertia delavayi].
OBJECTIVE
To isolate and identify the chemical constituents of 95% alcohol extract from Swertia delavayi.


METHODS
The compounds were isolated and purified by column chromatogrphy and their structures were identified by the physicochemical properties and spectral analyses.


RESULTS
Seven compounds were isolated and identified as oleanolic acid (1), gentiopcroside (2), swertiamarin (3), daucosterol (4), swertiadecoraxanthone-II (5), isovitexin (6), isoorientin (7).


CONCLUSIONS
Compounds 2-7 were isolated from S. delavayi for the first time. While the compound 6 was firstly reported from the genus Swertia.
