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.
从酸枣种子中分离出一对非对映异构体，即二氧吲哚 - 3 - 羟基 - 3 - 乙酸1 - 2的N - 糖基化衍生物及其与黄酮类化合物的缀合物3 - 8。通过核磁共振光谱分析阐明了它们的结构，并采用圆二色性方法确定了绝对构型。使用自由基吸收能力（ORAC）测定法对化合物3 - 10的抗氧化能力进行了评估。
