Abstract

Alpha-benzoyloxypaeoniflorin (1), a new antioxidant monoterpene alpha-glycoside anomer was isolated from Paeonia suffruticosa along with known compounds, beta-benzoyloxypaeoniflorin (2), paeonolide, paeoniflorin and mudanpioside H. The structure of 1 has been determined by comparing spectral data with those of beta-benzoyloxypaeoniflorin (2). Compound 1 exhibited moderately potent radical scavenging activity on DPPH radical.

摘要

从牡丹中分离得到了一种新的抗氧化单萜α-糖苷端基异构体α-苯甲酰氧基芍药苷（1），以及已知化合物β-苯甲酰氧基芍药苷（2）、芍药内酯、芍药苷和牡丹皮苷H。通过将光谱数据与β-苯甲酰氧基芍药苷（2）的光谱数据进行比较，确定了1的结构。化合物1对DPPH自由基表现出中等强度的自由基清除活性。
