ANALYSIS OF WATER-SOLUBLE VITAMINS IN THE DRY EXTRACT OF SILYBUM MARIANUM L.

Medicinal products derived from plant raw materials play a vital role in the prevention and treatment of various diseases. Vitamins, despite their low quantitative content compared to proteins, fats, and carbohydrates, are essential organic compounds that ensure normal metabolic processes and maintain physiological balance. Their deficiency can lead to metabolic disorders, hypovitaminosis, and even severe pathological conditions. Milk thistle (Silybum marianum L.) is a medicinal plant widely used in hepatoprotective therapy due to its biologically active compounds. However, limited attention has been paid to the vitamin composition of its extracts. This study focuses on the determination of water-soluble vitamins in the dry extract of Silybum marianum L. seeds (after defatting) using high-performance liquid chromatography (HPLC).
