THE STUDY OF PHENOLIC COMPOUNDS THE LEAVES AND SHOOTS OF ROSEMARY (ROSMARINUS OFFICI-NALIS L.), INTRODUCED IN BOTANICAL GARDEN OF PYATIGORSK MEDICAL-PHARMACEUTICAL INSTITUTE

Abstract

The object of the study was the leaves and shoots of rosemary medicinal (Rosmarinus officinalis L.), introduced for 9 years in the conditions of Caucasian Mineral Waters (North Caucasus) in the Botanical garden of the Pyatigorsk medical and pharmaceutical Institute in the open ground with shelter for the winter. Preliminary identification of phenolic compounds in the extracts from leaves and shoots of rosemary were carried out by thin-layer chromatography (TLC), and found gallic acid, rosmarinic acid, quercetin and apigenin.The method of high-performance liquid chromatography (HPLC) at wavelengths of 254 and 330 nm in leaves and shoots rosemary drug found 10 compounds: flavonoids: catechin, epicatechin, quercetin, apigenin; phenolcarboxylic acids: caffeic, gallic, chlorogenic, ferulic, rosmarinic as well as ascorbic acid. The content of rosmarinic acid in terms of dry raw materials in rosemary leaves was 0.181–0.184%; in shoots 0.062–0.064%.The area of the Northern Caucasus can be considered as a promising area for cultivation of medicinal plants – rosemary medicinal (Rosmarinus officinalis) – for the production of medicinal plant raw materials with a high content of biologically active substances.
