摘 要:目的建立供含量测定用褪黑素的首批化学对照品。方法应用紫外光谱、红外光谱、核磁共振和质谱对褪黑素对照品进行结构鉴定,并采用HPLC进行纯度分析和含量测定。结果 HPLC测定本品含量为99.8%。结论本实验中褪黑素对照品的建立为保健食品中添加褪黑素的检测和监督提供有力支持。OBJECTIVE To establish the reference standard of melatonin.METHODS The structure of the reference standard was identified by UV,IR,NMR,and ESI-MS spectrophotometry.The purity was calculated by normalization method and self-contrasted dilution method.Furthermore,loss on drying,residue on ignition,and hygroscopicity were tested.RESULTS The purity was99.8% by normalization method and self-contrasted dilution method.COCLUSION The establishment of reference standards of melatonin can efficiently control the addtion of melatonin into functional foods.
