isoimperatorin

基本解釋

Methods Use weighing method to weight the dry matter and an HPLC method to determine the content of isoimperatorin in A. dahurica root.
方法采用稱重法測(cè)定白芷干物質(zhì)，高效液相色譜法測(cè)定根中異歐前胡素。
The content of imperatorin,isoimperatorin and oxypeucedanin hydrate in different samples was carried out by HPLC.
HPLC法測(cè)定水合氧化前胡素、歐前胡素、異歐前胡素的含量。結(jié)果:果實(shí)中香豆素的含量最高,莖中最低;
Conclusion: Freezing drying makes the losses of imperatorin and isoimperatorin lowest and excels others.
結(jié)論：冷凍干燥法白芷醇提物歐前胡素和異歐前胡素的損失最小，優(yōu)于其他方法。
The accumulation of isoimperatorin was the highest in the end of October when A. dahurica was harvest.
異歐前胡素積累量在10月底收獲時(shí)達(dá)到最大。
In conclusion, imperatorin and isoimperatorin were found to have vasorelaxing effects for the first time.
本課題創(chuàng)新點(diǎn)在于首次通過細(xì)胞膜色譜模型發(fā)現(xiàn)歐前胡素和異歐前胡素對(duì)大鼠腹主動(dòng)脈細(xì)胞膜有親和作用，并且通過現(xiàn)代藥理學(xué)實(shí)驗(yàn)發(fā)現(xiàn)兩者具有舒張離體大鼠腹主動(dòng)脈環(huán)的新活性。
