用恒温加速试验法对２％穿琥宁注射液贮存期进行预测并用紫外分光光度法在２５０ｎｍ处测定脱水穿心莲内酯琥珀酸半酯单钾盐吸光度，预测出室温下穿琥宁注射液贮存期为２．３１年。
The storage period of 2% kalliuronine injection was predicted by isothermal accelerated test and the absorbance of dehydroandrographolide succinic acid half-potassium salt was determined by ultraviolet spectrophotometry at 250 nm. It was predicted that the storage period of ketril dehydrosulfide injection at room temperature was 2.31. year.
