Abstract

Two new biflavonoids, daphnogirins A (1) and B (2), were obtained from the roots of Daphne giraldii. Their structures were established on the basis of the spectral data and X-ray diffraction data of the co-crystal of 1 and 2. Daphnogrins A and B have the same configuration at C-1 and opposite configurations at C-16 and C-17. Oxygen radical scavenging assay has indicated that they are of significant antioxidative activity.

摘要

从黄瑞香的根中获得了两种新的双黄酮类化合物，瑞香黄素A（1）和瑞香黄素B（2）。它们的结构是基于1和2的共晶体的光谱数据和X射线衍射数据确定的。瑞香黄素A和B在C-1处具有相同的构型，在C-16和C-17处具有相反的构型。氧自由基清除试验表明它们具有显著的抗氧化活性。
