- 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(chēng)重法測定白芷干物質(zhì)，高效液相色譜法測定根中異歐前胡素。
- The content of imperatorin,isoimperatorin and oxypeucedanin hydrate in different samples was carried out by HPLC. HPLC法測定水合氧化前胡素、歐前胡素、異歐前胡素的含量。結果: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(guò)細胞膜色譜模型發(fā)現歐前胡素和異歐前胡素對大鼠腹主動(dòng)脈細胞膜有親和作用，并且通過(guò)現代藥理學(xué)實(shí)驗發(fā)現兩者具有舒張離體大鼠腹主動(dòng)脈環(huán)的新活性。
- Taking A. dahurica yield and the accumulation of isoimperatorin as harvest aim, the optimal time for harvest is at the end of October. 以白芷產(chǎn)量和異歐前胡素積累量為白芷的收獲目標，10月底為白芷的收獲期，與傳統采收期一致。
- The results indicated that the metabolism of imperatorin was two compartment model, phellopterin and isoimperatorin were one compartment model. 結果表明，歐前胡素在大鼠體內代謝為二室模型，異歐前胡素和珊瑚菜素在大鼠體內代謝為一室模型；
- Conclusion Taking A. dahurica yield and the accumulation of isoimperatorin as harvest aim, the optimal time for harvest is at the end of October. 結論以白芷產(chǎn)量和異歐前胡素積累量為白芷的收獲目標，10月底為白芷的收獲期，與傳統采收期一致。
