Seven flavanol derivatives, including three biflavanoids (-), two flavonoids ( and ), and two spirobiflavonoids ( and ), were isolated from the bark of . The structure of the undescribed compound was elucidated based on HR-ESIMS, NMR spectroscopy, and electronic circular dichroism (ECD) calculations. All isolated flavanol derivatives were screened for their antioxidant capacity to scavenge DPPH and ABTS.
从……的树皮中分离出七种黄烷醇衍生物，包括三种双黄酮类化合物（-）、两种黄酮类化合物（ 和 ）以及两种螺双黄酮类化合物（ 和 ）。基于高分辨电喷雾电离质谱（HR-ESIMS）、核磁共振光谱（NMR）以及电子圆二色光谱（ECD）计算，阐明了未描述化合物 的结构。对所有分离出的黄烷醇衍生物进行了清除二苯基苦味酰基自由基（DPPH）和2,2'-联氮-双（3-乙基苯并噻唑啉-6-磺酸）二铵盐（ABTS）的抗氧化能力筛选。
