- Methods Use weighing method to weight the dry matter and an HPLC method to determine the content of isoimperatorin in A. dahurica root. 方法採用稱重法測定白芷干物質,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:冷凍乾燥法白芷醇提物歐前胡素和異歐前胡素的損失最小,優於其他方法。
- 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月底收穫時達到最大。
- In conclusion, imperatorin and isoimperatorin were found to have vasorelaxing effects for the first time. 本課題創新點在於首次通過細胞膜色譜模型發現歐前胡素和異歐前胡素對大鼠腹主動脈細胞膜有親和作用,並且通過現代藥理學實驗發現兩者具有舒張離體大鼠腹主動脈環的新活性。
- Taking A. dahurica yield and the accumulation of isoimperatorin as harvest aim, the optimal time for harvest is at the end of October. 以白芷產量和異歐前胡素積累量為白芷的收穫目標,10月底為白芷的收穫期,與傳統採收期一致。
- 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. 結論以白芷產量和異歐前胡素積累量為白芷的收穫目標,10月底為白芷的收穫期,與傳統採收期一致。
