Abstract

Objective: To study the chemical constituents of Swertia binchuanensis.

Methods: The constituents were separated and purifyed by conventional methods. Their structures were identified on the basis of spectral analysis such as 1H-NMR,13C-NMR.

Results: Seven compounds were isolated and identified as 1, 2, 3, 4-tetrahydro-1, 4, 8-trihydroxy-6-methoxyxanhone（ Ⅰ）, erythrocentaurin（ Ⅱ）,1-O-β-D-glucopyranosyl-1, 2, 3, 4-tetrahydro-4, 8-dihydroxy-6-methoxyxanthone（ Ⅲ）, maslinic acid（ Ⅳ）,1-hydroxy-3, 7-dimethoxyxanthone（ Ⅴ）,1, 8-dihydroxy-3, 5-dimethoxyxanthone（ Ⅵ）,1, 7-dihydroxy-3, 4, 8-termethoxyxanthone（ Ⅶ）.

Conclusion: All compounds were isolated from Swertia binchuanensis for the first time.
