Improved preparation of lipid products for phytosterols analysis with beta-sitosterol quantitation by GC-FID

This poster, presented at the SelectScience^® Virtual Analytical Science Summit 2022, describes the successful development of a method to quantitate beta-sitosterol concentration in saw palmetto extract, a vegetable oil dissimilar to traditional vegetable oils in that it contains a variety of lipids rather than primarily triglycerides. This method utilizes an improved preparation which proves to be repeatable and can be utilized on any lipid product containing trace levels of phytosterols.
