Abstract

Plants of the genus Paeonia are considered promising sources of natural sedatives. Primarily, roots and rhizomes are used as medicinal raw materials for the treatment of neurasthenia, neurosis, hypochondria, and insomnia. This study aimed to determine the quality of medicinal peony (Paeonia officinalis L.) introduced into Uzbekistan, based on parameters such as appearance, colour, odour, particle size, and overall quality. In addition, amino acid, vitamin, polysaccharide, flavonoid, and elemental compositions of the raw material were identified and quantitatively determined using advanced analytical methods. The results confirmed the quality and safety of the raw materials. Polysaccharide composition was represented by fructose, glucose, sucrose, and maltose. Water-soluble vitamins identified included ascorbic acid (C), thiamine (B1), riboflavin (B2), nicotinic acid (PP), pyridoxine (B6), and folic acid (B9). Twenty free amino acids were detected with a total concentration of 13.692 mg/g, including eight essential amino acids, confirming the high biological value of the material. Flavonoids such as rutin, quercetin, salidroside, luteolin, dihydroquercetin, and rosavin were also quantified. The significant presence of biologically active compounds demonstrates the potential of developing effective pharmaceutical preparations from the roots and rhizomes of medicinal peony.
