    Area of Science:

    • Biochemistry
    • Analytical Chemistry
    • Clinical Diagnostics

    Background:

    • Accurate quantification of plasma lipids is crucial for diagnosing and monitoring various metabolic and cardiovascular diseases.
    • Existing methods for plasma lipid profiling can be time-consuming or lack the ability to simultaneously measure multiple lipid classes.

    Purpose of the Study:

    • To develop and validate a novel, simultaneous method for quantifying major plasma lipid classes.
    • To provide a sensitive, linear, and reproducible analytical technique for clinical lipid analysis.

    Main Methods:

    • Simultaneous quantification of cholesterol, cholesterol ester, triacylglycerol, non-esterified fatty acid, and polar lipids in plasma.
    • Utilized umbelliferyl palmitate as an internal standard.
    • Employed chloroform/methanol extraction followed by silica gel chromatography on a quartz rod and flame ionization detection.
