建立了一种灵敏测定人血清中反式叶绿醌含量的方法。血清样品用己烷提取,在硅胶半制备HPLC柱上进行初步分离,通过添加[3H]叶绿醌测定回收率为80%。将含反式叶绿醌的洗脱液干燥后,进样于μBondapak C-18高效液相色谱柱,采用玻璃碳电极和Ag AgCl参比电极进行还原电化学检测,测定维生素的浓度。通过不同HPLC条件下的再色谱、水动力伏安、光降解等方法,证实了推测的维生素峰为反式叶绿醌。反式叶绿醌可检测到低至300 pg/ml,正常人血清浓度在1 ng/ml范围内。
A sensitive method for the determination of human serum trans-phylloquinone levels has been developed. Serum samples were extracted with hexane and subjected to preliminary separation on a silica semipreparative HPLC column with an 80% recovery as determined by the addition of [3H]phylloquinone. The portion of the eluate containing trans-phylloquinone was dried and injected into a μBondapak C-18 analytical HPLC column, and the concentration of the vitamin was determined by reductive electrochemical detection utilizing a glassy carbon electrode and and Ag AgCl reference electrode. The presumed vitamin peak was confirmed as trans-phylloquinone by rechromatography at different HPLC conditions, hydrodynamic voltamography, and photodegradation. As little as 300 pg/ml rans-phylloquinone could be detected, and normal human serum concentrations were found to be in the range of 1 ng/ml.
