STUDY OF THE COMPONENT COMPOSITION OF LEAVES OF SPECIES OF THE GENUS JUGLANS L. BY HPLC

Leaves of species the genus Juglans L. Juglandaceae family are promising types officinal medicinal plant materials, which preparations have an antimicrobial, restorative effect. In our opinion, contribution to antimicrobial activity, along with naphthoquinones, is also made by flavonoids contained in leaves various Therefore, there a need determine chemical composition using modern methods analysis. This article discusses results studying component nigra L., regia and cinerea microcolumn high performance liquid chromatography (HPLC) at analytical wavelength 360 nm. The conditions for chromatographic separation were established analysis extracts from It was determined that HPLC it possible identify - myricitrin, quercitrin, dominant diagnostically significant this type raw material. addition, contains aglycone myricitrin – myricetin. A similar flavonoid profile revealed two materials Hyperoside, juglanin found these species.
