benzoic and cinnamic acid derivatives, were isolated from the MeOH extract of the leaves of Zanthoxylum rigidum (Rutaceae). The structures of the compounds were determined on the basis of 1D‐ and 2D‐NMR, and MS analysis. It is the first time that a natural cyclic peptide has been isolated from the genus Zanthoxylum.
从硬皮花椒(Rutaceae)的MeOH提取物中分离出一种新的环肽,环zanthoxylane A(1),木脂体顺式和反式甲基吡咯烷酮,类黄酮异槲皮苷以及苯甲酸和肉桂酸衍生物的混合物。化合物的结构是根据1D和2D-NMR以及MS分析确定的。这是第一次从花椒属植物中分离出天然环状肽。
