Good separation of the enantiomers of 1-hexadecyl-2-hexadecanoyl-rac-glycerol was easily achieved within 10 min using hexane/ethylene dichloride/ethanol (80∶20∶1, v/v/v) as a mobile phase. Separation of the enantiomers of 1-hexadecyl-3-hexadecanoyl-rac-glycerol was more difficult and required about 80 min to achieve satisfactory peak resolution (0.8) using hexane/ethylene dichloride/ethanol (250∶20∶1, v/v/v) as a mobile phase.
