摘　　要：本文研究了原小檗碱型生物碱延胡索乙素水溶液的γ辐射分解。测得吸收剂量大于1.8kGy时分解产额,G(-),为2.2±0.3,剂量小于1.8kGy时G(-)随吸收剂量减小而增大。研究了辐照溶液的紫外光谱变化。用低压柱层析法分离了主要辐解产物,并用测定熔点及光谱和质谱等手段鉴定了主要辐解产物之一是巴马亭。测得巴马亭的生成G值随吸收剂量增大而减小,且有明显的后效应。讨论了巴马亭的形成机制。Radiolysis of aqueous solution of corydalis-B, an alkaloid, has been investigated.Yields of radiolyssis of Corydalis-B in aqueous solution equal 2.2±0.3when doses are larger than 1.8 kGr, they increase as doses are decrease.Palmatine is one of the main radiolysis products, it has been separated and identified.The G values of palmatine are decrease as doses increase, post effect has been observed.
