Abstract:
AIMTo study the active constituents of Swertia davidi Franch..
METHODSChromatography was used to isolate and purify the chemical components, their structures were identified by spectral analysis.
RESULTSThree compounds were identified as 1,7-dihydroxy-3,8-dimethoxyxanthone (gentiacaulein) (V), 1,8-dihydroxy-3,7-dimethoxyxanthone (methylswertianin) (VI) and 1,8-dihydroxy-3,4,7-trimethoxyxanthone (VII).
CONCLUSIONCompound VII is a novel xanthone, named daviditin A, the others were isolated from Swertia davidi Franch. for the first time.
