Abstract

This study is outlined to define the chemical composition and in vitro antioxidant activity of the extracts of aerial part and root of Eryngium campestre L. (Apiaceae) from Kosovo. Analysis of the chemical composition include determination of total ash, ash insoluble in hydrochloric acid, loss on drying and the content of water extract, as well as determination of flavonoids in aerial part and hemolytic activity of the root. The mineral composition (Zn, Fe, Cu, Mn, Ni, K, Co, Pb, Cd and Cr) in aerial parts and root has been studied using atomic absorption spectroscopy (AAS and ETAAS). Different part of E. campestre accumulate different amounts of investigated minerals. Antioxidant activity was determined by four various testing systems: DPPH assay, inhibition of production of hydroxyl radical, β-carotenebleaching assay, and inhibition of lipid peroxidation (TBA test). In DPPH system, ethanol extract of root of E. campestre exhibited higher radical-scavenging activity (IC50 = 0.72 mg ml-1) compared to the extract of the aerial part (IC50 = 1.14 mg ml-1). On the other hand, aerial part ethanol extract has exhibited stronger inhibition capacity on the production of hydroxyl radical in deoxyribose system than the root extract (50% and 45%, respectively). However, both ethanol extracts of E. campestre exhibited low antioxidant activity in β-carotenebleaching assay as well as, low capacity for inhibition of spontaneous lipid peroxidation in rat liver homogenate

Highlights

  • Eryngium campestre L. (Apiaceae) is perennial plant, spread in Spain, France, Germany, Balkan Peninsula and other scattered localities in Europe, and in Africa and Asia as well (Ingram, 2006)

  • The results suggest that E. campestre extracts act as non-specific donators for hydrogen atoms or electrons in the diphenyl-2-picrylhydrazyl radical (DPPH)-assay

  • Analysis of the chemical composition of the aerial part and root of Eryngium campestre from Kosovo showed that the content of total ash, ash insoluble in hydrochloric acid, loss on drying and the content of water extract were relatively constant regardles the differences in the characteristics of the locations and year of collection

Summary

Introduction

Eryngium campestre L. (Apiaceae) (field eryngo) is perennial plant, spread in Spain, France, Germany, Balkan Peninsula and other scattered localities in Europe, and in Africa and Asia as well (Ingram, 2006). (Apiaceae) (field eryngo) is perennial plant, spread in Spain, France, Germany, Balkan Peninsula and other scattered localities in Europe, and in Africa and Asia as well (Ingram, 2006). It has been used in folk medicine as an infusion to treat cough, whooping cough, urinary infections, disturbed functions of kidney, increased urine secretion, eliminating out stones and sand from kidney and bladder, against water retaining and other conditions on urinary tract, for regulation of the function of prostate. The root of eryngo is known as antispasmodic, aromatic, diaphoretic, diuretic, expectorant, galactofuge and stimulant (Petkov, 1982). There are none known hazards of Eryngium campestre, even more young shoots and roots are edible parts of the plant which can be cooked and used as an asparagus substitute and as an digested vegetable (www.gardenzone.info).
