ABSTRACT. Two major glycolipids of Curtobacterium
flaccumfaciens pathovar betae (a, b) and one of Rothia
dentocariosa (c)were isolated, purified and studied by
analytical methods, thin-layer chromatography (TLC),
gas-liquid chromatography (GLC), mass spectrometry (GC-MS) and
nuclear magnetic spectroscopy (NMR). The only components
detected in the samples were mannose, glycerol and fatty
acids. The sugar moiety of glycolipid a was a trisaccharide
and that of glycolipids b and c a disaccharide. The most
characteristic components of the two glycolipids detected in
the cells of C.flaccumfaciens pathovar betae were cyclopropane
fatty acid C17:0 and anteiso branched chain components C15:0
and C17:0. The only major fatty acid found in the glycolipid
of R.dentocariosa was anteiso acid C17:0. The three
glycolipids seem to represent an uncommon structure.
