The principal colouring components of the natural food colouring material annatto, the 9'-cis- and all-trans- isomers of bixin and norbixin, have been prepared in pure form. A reverse-phase HPLC method utilizing photodiode-array detection has been developed to enable their chromatographic and spectroscopic characterization. One minor component, a di-cis-isomer of norbixin has also been identified and characterized.
天然食用色素胭脂树橙的主要呈色成分——胭脂树素和降胭脂树素的9'-顺式异构体及全反式异构体，已被制备成纯品。已开发出一种利用光电二极管阵列检测的反相高效液相色谱法，以实现对它们的色谱和光谱表征。还鉴定并表征了一种次要成分——降胭脂树素的二顺式异构体。
