摘要
阿胶水液（Ｍｕｒｐｈｙ法）与其经Ｇｏｒｎａｌｌ双缩脲和Ｌｏｗｒｙ酚试剂反应后的吸收光谱特征皆与参比明胶同一。以明胶作标准，用上述各光度法测定阿胶蛋白质结果彼此近似并与定氮法一致。
jiao exhibits identical
spectral characteristics with those of reference gelatin in Murphy’s
UV spectrophotometryand color-yielding reactions performed according
to Gornall’s biuret and Lowry’s Folin phenol procedures
respectively.Results of protein assays of Ejiao measured by
above-mentioned photometric methods were in gcod appro-ximation
toeach other using gelatin as standard and comparable with that of
Kjeldahl nitrogen determination.
