作者分析了大戟科地杨桃属植物Sebastiania schottiana的主要成分一二羟4,6-二甲氧乙酰苯(花椒油素xanthoxyline)对由激动剂和电刺激引起的平滑肌和心肌收缩的抑制作用。花椒油素(30～300μmol/L)抑制了由几种激动剂以非竞争性、非选择性及浓度相关的方式引起的大鼠子宫及豚鼠回肠和膀胱的 The authors analyzed the inhibition of smooth muscle and myocardial contraction caused by agonists and electrical stimulation of the major component, dihydroxy-4,6-dimethoxyacetophenone (xanthoxyline), of the genus Sebastiania schottiana of Euphorbiaceae. Zanthoxylin (30-300 μmol/L) inhibits the ileum and bladder of rat uterus and guinea pigs caused by several agonists in a non-competitive, non-selective and concentration-dependent manner.
