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.
提供了一种制备脱氢阿匹卡啶、脱氢阿匹可卡啶及其相应组合物的方法。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“燕黄连”(岩黄堇科黄堇属)中分离和纯化季
铵类
生物碱成分制备而成,然后干燥以获得含有脱氢阿匹卡啶和脱氢阿匹可卡啶的该组合物。必要时,该组合物或其粗
提取物可以通过色谱分离获得脱氢阿匹卡啶或脱氢阿匹可卡啶。脱氢阿匹卡啶、脱氢阿匹可卡啶或其相应组合物可用于制造治疗病毒性肝炎、肝损伤、流感、艾滋病、肿瘤或心律失常的药物。
