中文摘要：

生物碱是自然界中广泛存在的一类天然含氮有机化合物，具有比较特殊而显著的药理活性。近年来免疫学分析技术常应用于天然药物生物碱的研究，而制备具有良好免疫原性的人工抗原并对其进行鉴定，是建立免疫学分析方法用于生物碱研究的前提和关键。本文主要总结了天然药物中生物碱半抗原与载体蛋白偶联的设计思路及其鉴定方法。

英文摘要：

Alkaloids are a kind of natural nitrogen compounds which are widespread in the nature, with special and significant activities in pharmacology. In recent years, immunoassay techniques have been applied for the qualitative and quantitative analysis of alkaloids from traditional Chinese medicine （TCM）. However, preparation and identifica-tion of artificial antigen with good immunogenicity are necessary and important for establishment of immunoassay for alkaloids from TCM. This paper summarized the designing ideas and procedures for preparation of artificial antigen and identification for the conjugates of alkaloids and carrier protein, in order to provide reference point for establish-ment and application of immunoassay techniques.
