A method for preparing dehydrocavidine, dehydroapocavidine and their respective composition is provided. The composition is first prepared by isolating and purifying the quaternary ammonium alkaloid components from the medicinal plant “Yan Huang Lian” (
Corydalis saxicola
Bunting) through the processes of solvent extraction, water-phase organic extraction, crystallization and recrystallization, and then drying to obtain said composition containing dehydrocavidine and dehydroapocavine. When necessary, the composition or their crude extracts can be separated by chromatography to obtain dehydrocavidine or dehydroapocavidine. Dehydrocavidine, dehydroapocavidine or their respective composition can be used in manufacturing medicines for treating viral hepatitis, hepatic injury, influenza, AIDS, tumors or arrhythmia.
提供一种制备脱氢洋黄连碱、脱氢异洋黄连碱及其组合物的方法。该组合物首先通过溶剂萃取、水相有机萃取、结晶和重结晶等过程,从药用植物“岩黄连”(Corydalis saxicola Bunting)中分离和纯化季铵类生物碱成分,然后经过干燥以得到含有脱氢洋黄连碱和脱氢异洋黄连碱的组合物。必要时,可以通过色谱分离组合物或其粗提取物以得到脱氢洋黄连碱或脱氢异洋黄连碱。脱氢洋黄连碱、脱氢异洋黄连碱或其组合物可用于制造治疗病毒性肝炎、肝损伤、流感、艾滋病、肿瘤或心律不齐的药物。
