Two new compounds, including a norsesquiterpenoid, annuionone H (), and a quassinoid, picraqualide G (), along with eleven known compounds (), were isolated from the twigs and leaves of . Comprehensive spectroscopic analyses and NMR calculation with DP4+ analysis were used to identify their structures. Moreover, of all these compounds, compound showed a week inhibition rate in the anti-inflammatory screening results against mouse macrophage J774A.1 cell.
从羊角拗的嫩枝和叶中分离得到了两个新化合物，包括一个新的降二萜类化合物 annuionone H () 和一个新的三萜类化合物 picraqualide G ()，以及 11 个已知化合物 ()。通过综合光谱分析和 DP4+ 分析的 NMR 计算确定了它们的结构。此外，在抗炎筛选实验中，所有这些化合物中，化合物 对小鼠巨噬细胞 J774A.1 细胞的抑制率较弱。
