    Area of Science:

    • Phytochemistry
    • Plant-derived compounds
    • Natural product analysis

    Background:

    • Equisetum arvense L. (common horsetail) is a widely recognized medicinal plant.
    • Sterols are vital components of plant cell membranes with diverse biological activities.
    • Understanding the sterol composition of medicinal plants is crucial for quality control and therapeutic potential.

    Purpose of the Study:

    • To identify and quantify the major sterols present in the sterol fraction of Equisetum arvense L.
    • To provide detailed chemical profiling of Equisetum arvense L. sterols.
    • To establish a basis for the standardization of Equisetum arvense L. extracts.

    Main Methods:

    • Sterol extraction from Equisetum arvense L. material.
    • Gas-Liquid Chromatography (GLC) and High-Performance Liquid Chromatography (HPLC) for sterol quantification.
    • Nuclear Magnetic Resonance (NMR) and Mass Spectrometry (MS) for sterol identification.

    Main Results:

    • The sterol fraction is predominantly composed of beta-sitosterol (60.0%) and campesterol (32.9%).
    • Isofucosterol (5.9%) and trace amounts of cholesterol were also identified.
    • Quantitative data from GLC and HPLC were correlated with structural information from NMR and MS.

    Conclusions:

    • Equisetum arvense L. possesses a distinct sterol profile rich in beta-sitosterol and campesterol.
    • The identified sterols are key bioactive compounds in Equisetum arvense L.
    • This detailed sterol analysis supports the medicinal use and standardization of Equisetum arvense L.
