isoimperatorin

基本解释

Methods Use weighing method to weight the dry matter and an HPLC method to determine the content of isoimperatorin in A. dahurica root.
方法采用称重法测定白芷干物质，高效液相色谱法测定根中异欧前胡素。
The content of imperatorin,isoimperatorin and oxypeucedanin hydrate in different samples was carried out by HPLC.
HPLC法测定水合氧化前胡素、欧前胡素、异欧前胡素的含量。结果:果实中香豆素的含量最高,茎中最低;
Conclusion: Freezing drying makes the losses of imperatorin and isoimperatorin lowest and excels others.
结论：冷冻干燥法白芷醇提物欧前胡素和异欧前胡素的损失最小，优于其他方法。
The accumulation of isoimperatorin was the highest in the end of October when A. dahurica was harvest.
异欧前胡素积累量在10月底收获时达到最大。
In conclusion, imperatorin and isoimperatorin were found to have vasorelaxing effects for the first time.
本课题创新点在于首次通过细胞膜色谱模型发现欧前胡素和异欧前胡素对大鼠腹主动脉细胞膜有亲和作用，并且通过现代药理学实验发现两者具有舒张离体大鼠腹主动脉环的新活性。
