A novel cycloartane triterpene glycoside from the seeds of Cassia sophera L.

Abstract

A new cycloartane triterpene glycoside (1), named Cyclosophoside A, was isolated from the seeds of Cassia sophera L. The structure of 1 has been determined as 29-O-β-D-glucopyranoside of 1α, 3β, 24ξ, 25-tetrahydroxy-9, 19-cycloartan-29-oic acid by means of physicochemical properties and spectroscopic methods (1D and 2D NMR, MS).

Keywords:

• Cassia sophera L.
• Cycloartane triterpene glycoside
• Cyclosophoside A
