【摘要】 本文采用紫外分光光度法于λ278±1nm波长处测定优青糖苷的含量,并研究了测定条件。该法平均回收率为100.6%,变异系数为0.25%,且操作简便,结果稳定。同时用本法对优青糖苷的稳定性进行了考察。更多还原

【Abstract】 By means of ultraviolet spectrophotometry, the content of bredinin was determinated, and the condition for the determination was also investigated. The recovery was 100.6%, and the coefficients of variation was 0.25%. The benefits of this method are simple and exact, the results are stable as well. then the stability of bredinin in water was studied.更多还原
