Description

Description générale

Squalene is a naturally occurring triterpenoid and a precursor to sterol biosynthesis. Typically isolated from shark liver, olive, amaranth, and algal oils, it shows various cosmetic and medicinal uses.

Application

This analytical standard can also be used as follows:

• Analysis of 119 vegetable oil samples from 7 different varieties to detect and determine squalene and four sterols using a developed and validated non-destructive method based on proton nuclear magnetic resonance (¹H NMR) spectroscopy combined with partial least squares (PLS) method
• Determination of squalene in different oil samples by gas chromatography coupled to flame ionization detection (GC-FID) following base-catalyzed transmethylation of the oil base
• Ultra-high performance liquid chromatography-photodiode array detection (UHPLC-PDA) based quantification of squalene, following its single-step solid phase extraction (SPE) from 33 samples of extra virgin olive oil collected from different countries
• Measurement of squalene content of 16 commercial shark liver oil samples using a gas chromatography-mass spectrometry-based method, in addition to IR and Raman spectroscopy combined with the PLS method
• Multi-residue determination of 14 naturally occurring compounds— squalene, tocopherols, and phytosterols, following their solid phase extraction (SPE) from 15 vegetable oil samples by GC-MS
