Abstract
A new caffeoylgluconic acid derivative, trans-caffeoyl-6-O-d-gluconic acid methyl ester (1), together with two known compounds named trans-caffeoyl-6-O-d-glucono-γ-lactone (2) and trans-caffeoyl-6-O-d-gluconic acid (3), was isolated from the nearly ripe fruits of Evodia rutaecarpa (Juss.) Benth.. These compounds were isolated by various separation methods associated with the UPLC-Q-TOF-MS technique. Their structures were elucidated on the basis of extensive spectroscopic methods.
