title: High-performance liquid chromatographic analysis of demethylmenaquinone and menaquinone mixtures from bacteria.
abstract: Demethylmenaquinone and menaquinone mixtures from some species of enterobacteria were analysed by reverse-phase partition high-performance liquid chromatography. This method allowed clear separation and quantitative determination of these quinone components.
