Abstract


In the unsaponifiable matter of refined olive oils and, frequently, virgin olive oils of bad quality, a new compound with polarity between those of squalene and triterpenic alcohols was isolated.
Mass spectrometry of this compound and of their hydrogenated and; sililated derivatives, demonstrated that the compound was a long chain alcohol having 426 of molecular weight, polyisoprenic structure similar to that of squalene, and the hydroxyl group attached at the C-2 carbon atom.

Keywords
