New isoprenologs of vitamin K2 series in Sarcina lutea.

Four new menaquinone homologs have been isolated and characterized from Sarcina lutea. The use of purified silica gel G in the isolation of pure menquinones from bacterial nonpolar lipids has been developed. During this procedure, fractionation of any naturally occuring menaquinones with sidechain variation takes place. The structures of the isolated menaquinones have been elucidated by UV-, and mass spectrometry, and by their corresponding hydroquinones and layer chromatography properties. Thus, Sarcina lutea has been shown to produce four homologs of dihydromenaquinones, i.e., dihydromenaquinone-6,-7,-8, and -9.[1]
