摘要
A method which assays the alkaloid in the presence of its breakdown products has been used to investigate the effects of heating and exposure to ionizing radiations on the degradation kinetics of aqueous physostigmine solutions. Maximum stability at 90***° is between pH 2·2 and 3·0. Sodium metabisulphite retards the degradation of physostigmine when exposed to gamma irradiation, but has no effect on the degradation by heat. 1968 Royal Pharmaceutical Society of Great Britain
