Measuring Phytosterols in Health Supplements by LC/MS

Instrument Type: LCMS

Plant sterols, phytosterols, are claimed to help lower cholesterol levels in humans. In the year 2000, the United States Food & Drug Administration (US FDA) approved a health claim relating phytosterol ester or phytostanol ester consumption to reduced risk for coronary heart disease. Thus, there is increased interest in qualitative and quantitative analysis of phytosterols in food products. Phytosterols are typically measured by gas chromatography after derivatization. In this study, phytosterols were injected onto an LC-MS for direct analysis.
