    This study introduces a fast and simple column chromatography method for extracting steroid hormones from plasma, improving efficiency and eliminating emulsion issues common in liquid-liquid extraction.

    Area of Science:

    • Biochemistry
    • Analytical Chemistry
    • Endocrinology

    Background:

    • Traditional liquid-liquid extraction for steroid hormones is time-consuming and prone to emulsion formation.
    • Accurate quantification of steroid hormones in plasma is crucial for diagnosing endocrine disorders.

    Purpose of the Study:

    • To develop a simplified and efficient method for steroid hormone extraction from plasma.
    • To overcome the limitations of conventional extraction techniques, such as emulsion formation and time expenditure.

    Main Methods:

    • A novel column chromatographic technique was employed for steroid hormone extraction.
    • The method allows for nearly quantitative separation of steroids in a single step.
    • Selective extraction of estriol from estrone and estradiol was specifically addressed.
