Zotsenko L. Pharmacognostic study of representatives of Elsholtzia genus

The dissertation is devoted to the complex pharmacognostic study of representatives of Elsholtzia genus: Vietnamese lemon balm (Elsholtzia ciliata (Thunb.) Hyl.) and mintshrub (Elsholtzia stauntonii Benth.), obtaining and phytochemical research of medicinal products based on promising medicinal plant materials (PRM), as well as standardization of PRM and obtained herbal medicinal products. With the help of chemical and physico-chemical research methods, the quantitative content of amino acids, carbohydrates, organic, phenolic and hydroxycinnamic acids, flavonoids, anthocyanins, catechins, tannins, chlorophylls, carotenoids, phytosterols, fatty acids, volatile compounds, macro- and microelements were found. The morphological and anatomical structure and ultrastructure of the surface of the epidermal tissue of Elsholtzia ciliata and Elsholtzia stauntonii herb was studied, and standardization parameters were proposed. A method of obtaining Elsholtzia ciliata and Elsholtzia stauntonii herb dry extracts was developed and standardization parameters were proposed for this extract. Acute toxicity and pharmacological activity were studied for Elsholtzia
