摘要: 本文利用延胡索中叔胺碱和季铵碱两类生物碱的不同电荷性质,通过调节流动相的种类及pH值,提出了一种分离制备叔胺碱和季铵碱类组分的新方法。通过该方法得到的两类生物碱,含量分别达到了84.0%和60.7%,可满足中药有效部位制剂开发的要求。对所制备的生物碱类组分进行了多巴胺D2受体细胞拮抗活性评价,结果表明延胡索多巴胺D2受体拮抗作用主要集中在叔胺碱组分中,验证了两类生物碱组分不同的药理活性,为延胡索生物碱化学成分研究及有效部位制剂开发提供了理论及实验依据。

Abstract: In this paper,a new method for the separation and preparation of tertiary alkaloids and quaternary alkaloids from Rhizoma Corydalis was proposed by adjusting the type and pH value of mobile phase.The content of the two types of alkaloids obtained by this method reached 84.0% and 60.7% respectively,which could meet the requirements for the development of effective parts preparations of traditional Chinese medicine.The prepared alkaloids were evaluated for dopamine D2 receptor cell antagonism,the results showed that the antagonism of dopamine D2 receptor of Rhizoma Corydalis was mainly concentrated in the tertiary amines,which verified the different pharmacological activities of the two alkaloids,and provided the theoretical and experimental basis for the research of alkaloids and the development of effective part of Corydalis.

Key words: Rhizoma Corydalis, tertiary alkaloids, quaternary alkaloids, liquid chromatography separation
