| Abstract: | Objective To synthesize 3 H higenamine. Methods The synthesis consisted of catalytic tritium gas addition and demethoxylation. 3 H higenamine was purified by thin layer chromatography and identified by UV and HPLC. Results The UV and HPLC spectrum of the synthesized 3 H higenamine were identical with that of the higenamine standard, the radiochemical purity was more than 98% and the specific activity was 370 GBq/mmol. Conclusion An effective method for synthesis of 3 H higenamine in small scale is developed, and it makes the further pharmacodynamical research of higenamine feasible. |
