Abstract

The raw material for ergocalciferol was tested for preparation of the "Ergocalciferol Reference Standard (Control 941)". Analytical data obtained were as follows: melting point, 117.6 degrees C; UV and infrared spectra, the same as those for JP Cholecalciferol Reference Standard; specific absorbance, E1%1cm = 458 (265 nm); thin-layer chromatography and high-performance liquid chromatography (HPLC), no impurities were detected, respectively; assay, 100.6% by HPLC. Based on the above results, the candidate raw material was authorized as the Japanese Pharmacopoeia Reference Standard (Control 941).

麦角钙化醇参考标准(Control 941)国家卫生科学研究所。
为编制《麦角钙化醇标准品(对照品941)》,对麦角钙化醇的原料进行了检测。得到的分析数据如下:熔点117.6℃;紫外和红外光谱,与JP胆钙化醇标准品相同;比吸光度,E1%1cm = 458 (265 nm);薄层色谱法和高效液相色谱法,均未检出杂质;高效液相色谱法测定100.6%。根据上述结果,该候选原料被批准为日本药典参考标准(Control 941)。
