Abstract:

Polyglycerol esters of fatty acids were analyzed by high-performance liq. chromatog. with a 25 cm × 4.6 mm column packed with 10 $μ$m LiChrosorb Diol. The isomers were eluted by gradient with a hexane-iso-PrOH mixt. within 60 min, and the components monitored by UV absorption at 220 nm. Monoglycerol and polyglycerol monoesters, as well as polyglycerol polyesters of oleic acid, were sepd. and evaluated. [on SciFinder(R)]
