南部断阶带是高邮凹陷南部的一个二级构造单元，长期以来真①、真②及真②′等主干断层的发育历史模糊不清，本论文通过对构造演化的分析及对断层活动的定量研究重新厘定了三条主干断层的发育历史，并利用构造物理模拟实验对其进行了验证。

Important advance was made to Celastrus and ceangulin V after 20 years studies, but the target of Celangulin V was not verified and the metabolic dynamic of Celangulin V in organism was not touched because of the technique difficulty in testing and analysis of trace Celangulin V in organism. It will solve the difficulty that establishing the immunoassay of Celangulin V. The immunoassay of Celangulin V including the synthesis of artificial antigen, the preparation of antiserum, the immunoanalysis location of Celangulin V and the quantitative immunoassay of Celangulin V were studied systematicly in this paper.

苦皮藤素V是从卫矛科植物苦皮藤中分离出的一种具有杀虫活性的天然产物，可能作用于一类新的作用靶标。20多年对苦皮藤及苦皮藤素V的研究已取得了重要进展，但迄今还没有证实苦皮藤素V的作用靶标，对苦皮藤素V在生物体内的药代动力学研究也尚未涉及，这些方面的研究因为对痕量苦皮藤素V在生物体内分析、检测存在技术方法上的困难而受到限制，建立苦皮藤素V的免疫分析技术则可解决这些问题。
