Generation of acetyl glyceryl ether phosphorylcholine from the rat skin and muscle tissues stimulated by moxibustion.

Platelet-activating factor was obtained from the rat skin and muscle tissues which were stimulated by moxibustion. It showed a typical aggregation pattern on interaction with washed rabbit platelets but when it was treated with phospholipases A2 and C, and CV 3988 the aggregation activity was lost. Platelet-activating factor was hydrolysed with phospholipase C and the resulting lipid product was converted to the tert-butyldimethylsilyl derivative. After purification by thin layer chromatography, the ether type of derivative was analysed by a selected ion monitoring technique of gas chromatography-mass spectrometry. 1-0-Hexadecyl-2-acetyl-sn-glyceryl-3-phosphorylcholine only was identified.
