Abstract:
Genistein and daidzain are two primary soybean isoflavones，which have important biological activities.There are few reports about their structure analysis at the same time.The molecular structures of genistein and daidzain were analyzed at the same time by mass spectrum，infrared spectrum，1H-nuclear magnetic resonance(NMR) spectrum，13C-NMR spectrum and Two-dimension-NMR spectrum，which offers a useful method for the fingerprint analysis of mixture.To make sure the truth of mixture structure analysis，the article analyzed the molecular structures of genistein and daidzain from the aspect of molecular weight，primary function group and material structure.The method makes sure of the correctness of mixtures’structures and avoides separating mixtures before analyzed.The method is proved to be easy and fast.
