Abstract

Aim: To study the active constituents of Swertia davidi Franch..

Methods: Chromatography was used to isolate and purify the chemical components, their structures were identified by spectral analysis.

Results: Three 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).

Conclusion: Compound VII is a novel xanthone, named daviditin A, the others were isolated from Swertia davidi Franch. for the first time.
