Five phospholipids in human placenta were determined by phosphorus 31 nuclear magnetic resonance (³¹P NMR) spectroscopy and thin-layer chromatography (TLC) scanning combined with the corrective method of absorbance proportional coefficient. The NMR spectrometer used this investigation was a Bruker AM-500 spectrometeroperating at 202.4 MHz for ³¹P chemical shifts are relative to 85% phosphoric acid. TIC was carried out by silica gel H plate developed in chloroform-methanol-glacialacetic acid-ethanol-water (25:4:6:2:0.5), with Vaskovsky reagent as colour-developing agent of phospholipids.
