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.

Summary

SUMMARY

Component of the unsaponifiable portion of olive oil with polarity between those of squalene and triterpenic alcohols. 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. KEY-WORDS: Component of intermediate polarity - Isoprene alcohol - Refined olive oil - Unsaponifiable
