THE IMPACT OF APPLICATION OF DIFFERENT MACROPOROUS ADSORPTION RESINS AND DESORPTION SOLVENTS ON ANTIBACTERIAL AND ANTIOXIDANT EFFECTS OF SAGE LEAF EXTRACTS (Salvia officinalis L.) OBTAINED BY EUTECTIC SOLVENT

Abstract

Kadulja (Salvia officinalis L.) se smatra jednom od komercijalno važnijih vrsta iz porodice usnača (Lamiaceae). U cvijetu, listovima i stabljici ljekovite kadulje identificiran je širok raspon kemijskih spojeva koji imaju širok raspon učinaka zbog čega se široko koristi u prehrambenoj, farmaceutskoj i kozmetičkoj industriji. U ovom radu ispitan je utjecaj upotrebe različitih makroporoznih adsorpcijskih smola i desorpcijskih otapala na antioksidativnu i antibakterijsku aktivnost ekstrakata kadulje. Ovim istraživanjem utvrđeno je da upotreba desorpcijskih otapala ima utjecaj na ukupni sadržaj fenola, antioksidacijsku i antibakterijsku aktivnost. Primjena DIAION HP 2mg smola sa 70 %- tnim i 100 %-tnim etanolom pokazala je povećanje antioksidacijske aktivnosti, a najveći udio fenola zabilježen je kod ekstrakata gdje je primijenjena AMBERLITE XAD 16N smola i 100 %- tni etanol. Najučinkovitije antibakterijsko djelovanje ekstrakta dobivenih primjenom AMBERLITE XAD 7HP smole neovisno o otapalu zabilježeno je protiv soja P. aeruginosa.Sage (Salvia officinalis L.) is considered to be one of the most commercially important species of Lamiaceae family. The studies of the sage flower, leaves and stem has shown the great variability of chemical components which have a wide range of effects. For that reason sage is widely used in food, pharmaceutical and cosmetic industries. In this study the impact of application of different macroporous adsorption resin and desorption solvents on antioxidant and antibacterial effects of sage extract was tested. This reasearh has enstablished that application of DIAION HP 2MG resin with 70 % and 100 % ethanol has shown increased antioxidant activitiy. The highest total phenolic content was found in extracts obtained with AMBERLITE XAD 16N resin and 100 % ethanol. Extracts obtained with AMBERLITE XAD 7HP resin regardless of solvent used have shown the most effecient antibacterial activity against P. aeruginosa
