GC-MC analysis of the major pig epidermis triol. A, electron ionization mass spectrum of authentic triol-3 as the PFB ester, DMP acetonide, trimethylsilyl ether derivative. B, major esterified triol from pig skin was collected from SP-HPLC as the PFB DMP derivative, converted to the TMS ester derivative, and analyzed by GC-MS, exhibiting the same GC retention time and essentially identical mass spectrum to the authentic standard.
