helenium amarum/抗氧化剂

Previously we have reported that several sesquiterpene lactones isolated from Helenium aromaticum and Telekia speciosa showed pro-oxidative properties and caused glutathione level depletion in rat liver in vivo. In the present study we examined the in vivo effect of these lactones on antioxidant

Variations in abiotic environmental factors have significant effects on quantity and quality of secondary metabolites, which is particularly important for plant species that possess biologically active compounds. The purpose of this study is determination of the total phenolic content, flavonoid

In this study, the effects of dietary methanol and n-hexane extracts of elecampane rhizome (MEER and HEER, respectively) on growth performance, apparent ileal nutrient digestibility (AID), ileal microbiota, intestinal morphology and antioxidant status of the intestinal mucosa were compared in

UNASSIGNED The aim of this study is to explore the antioxidant and antiproliferative activities of aqueous extract from aerial parts of Inula helenium (L.) against human U-87 MG glioma cell line. UNASSIGNED The 3'-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide and lactate dehydrogenase

The aim of the current research was to perform two "green chemistry" extractions (ultrasound and microwave irradiation) with methanol, 70% (v/v) ethanol and water for extraction of biologically active substances from elecampane (Inula heleniun L.) roots and to compare their contents in all extracts.

The antistressor and antioxidant properties of preparations from the underground part of elfwort (Inula helenium) were studied on a model of acute stress in mice. The preparations produced a protective effect with respect to internal organs, blood, carbohydrate metabolism, and lipid peroxidation

Our previous study showed that a methanol extract of Inula helenium had the potential to induce detoxifying enzymes such as quinone reductase (QR) and glutathione S-transferase (GST) activity. In this study the methanol extract was further fractionated using silica gel chromatography and vacuum

Inula helenium has been reported to contain a large amount of phenolic compounds, which have shown promise in scavenging free radicals and prevention of neurodegenerative diseases. This study is to investigate the neuroprotective effects of total phenolic compounds from I. helenium on hydrogen

Our previous study showed that the methanolic extract of Inula helenium (elecampane) had the potential to induce detoxifying enzymes such as quinine reductase (QR) and glutathione S-transferase. In this study we further fractionated the methanolic extract into hexane-, dichloromethane-, butanol-,

Our previous study demonstrated that methanolic extract of Inula helenium (Elecampane) has the potential to induce detoxifying enzymes such as NAD(P)H:(quinone acceptor) oxidoreductase 1 (EC 1.6.99.2) (NQO1, QR) activity and glutathione S-transferase (GST) and found isoalantolactone and
