【摘要】 本文用初均速法预测了丹参注射液中主要成分原儿茶醛的稳定性。选择了9个温度进行了恒温加速实验。用铁氰化铁比色法于721分光光度计上测定了丹参注射液的光密度数值。用 BASIC语言编制出计算程序,将光密度数据输入苹果机（Apple-Ⅱ）进行运算。画出了 lnV 和 1/T 的 Arrhenius图,算出了直线相关系数 r=0.995,建立了直线回归方程 Y=-14178.53x+36.55,预测了丹参注射液中主要成分原儿茶醛的稳定性:t_0.9=1.67年,t_0.8=3.55年,t_0.7=5.67年。更多还原

【Abstract】 The concentration changes of the principleconstituent of Danshen injections,3,4-dihyd-roxybenzaldehyde,were measured colorimetri-cally with 721-spectrophotometer,using theinitial average rate method.Samples of injections were subjected toisothermal acceleration test under 9 differenttemperatures.Data on concentration changesobtainad by the tests were treated by comput-er program.The relationship of arrhenius pl-ot of lnv versus 1/T was linear with a corr-elation coefficicnt R of 0.995.The activat-ion energy E was found to be E=11788.25 J.tool^-1.The predicted t_0.9 was 1.67 years,t_0.8 3.55 years,t_0.7 5.67 years.更多还原
