Abstract

A pair of diastereoisomers, the N-glycosylated derivatives of dioxindole-3-hydroxy-3-acetic acid 1-2, and their conjugates with flavonoids 3-8, was isolated from the seeds of Ziziphus jujuba var. spinosa. Their structures were elucidated by NMR spectroscopic analyses, and the absolute configurations were determined by circular dichroism method. Compounds 3-10 were evaluated for the antioxidant capacity, using the radical absorbance capacity (ORAC) assay.
