摘要
探讨了影响复合维生素Ｂ片中维生素Ｂ２含量测定结果偏高的因素，采用在加入溶剂后于８０℃恒温水浴中加热３０ｍｉｎ使维生素Ｂ２溶解，用分光光度法测定，消除了辅料中玉米淀粉与硬脂酸镁的干扰，操作简便，结果准确，平均回收率为１００．３％（ｎ＝５）。
The result of determination of vitamin B2 content in vitamin B complex tablet leans toward high,the factors that influence the result are discussed in this paper. Added solvent into water bath with constant temperature 80℃ and heated for 30 min,making vitamin B2 dissolved,and determined with spectrophotometry. The interference of corn starch and magnesium stearate was eliminated. This measure was liable to operate and the result was accurate. The average recovery rate was 100.3%(n=5).
