Chemical Constituents of Swertia angustifolia Buch.

Abstract

Abstract:

Objective: To explore the chemical constituents of Swertia angustifolia Buch. Methods: Compounds were separated and
purified by silica gel column chromatography and their structures were elucidated on the basis of physicochemical properties and
spectral analysis. Results: Four monomeric compounds were obtained from trichloromethane extract of S. angustifolia and were
identified as asoleanolic acid（1）, ursolic acid（2）, lupeol（3）, and 3β- hydroxy- 11α,12α- epoxyoleanan- 28,13β- olide（4）.
Conclusion: Compounds（2）,（3）and（4）were obtained from S. angustifolia for the first time.

Key words: Swertia angustifolia Buch., chemical constituents, terpenoids
