title: Separation and quantitation of glycolipids as penetration modifiers in human skin using high-performance liquid chromatography-mass spectrometry with electrospray ionization.
abstract: An high-performance liquid chromatography-mass spectrometry method is presented for the measurement of glycolipids used as modulators of the penetration of drugs into human skin. In methanol extracts from different skin layers a detection limit of 100-400 pg/ml could be achieved. A routine analytical procedure could be set up with good quantitation reliability (relative standard deviation 6.6%).
