HPTLC Chromatographic Polyphenolic Fingerprints of Plant Species from Eastern Europe

Abstract

Polyphenols are plant secondary metabolites. They are important active principles from medicinal plants and food supplement that contain medicinal plants. Experimental data indicate that polyphenols exhibit biological functions, as protection against oxidative stress and degenerative diseases. For identification of polyphenolic compounds in plants high-performance thin layer chromatography (HPTLC) is one of the simple and accurate method, which provide important information regarding chemical composition. The chromatographic polyphenolic fingerprint of the four species analysed (Allium sativum - garlic- green leaves, Allium ursinum - wild garlic - green leaves, Malus pumila - apple tree - leaves, Pyrus communis - pear tree - leaves) revealed the present of  flavonoid glycosides and  hydroxycinnamic acids compounds. Because for all the four species for nutritional and therapeutic purpose are used other part of them (garlic and wild garlic- bulbs and apple and pear-fruits) the results obtained can be a first step for superior valorification of hole plant.
