hedera colchica/抗氧化剂

Two new protocols for exploring antioxidant-related chemical composition and reactivity are described: one based on a chronometric variation of a haemoglobin ascorbate peroxidase assay and one based on cytochrome c-induced oxidation of lecithin liposomes. Detailed accounts are given on their design,

The purpose of this study was to examine the effects of powder particle size on the cytoprotective and antioxidant activity of Hedera helix (HH) and Scrophularia nodosa (SN), two medicinal plants more commonly known as ivy and figwort, against H₂O₂-induced

Antioxidant potential of four methanol extracts from three selected plant species, namely Salvia nubicola (Lamiaceae), Acer oblongifolium (Aceraceae) and Hedera nepalensis (Araliaceae) was measured using assays in aqueous and lipid systems. Antioxidant activities were investigated in aqueous systems

Exposure to high doses of acetaminophen is the most common cause of drug induced liver injury. We investigated the protective effects of Hedera helix extract against acetaminophen induced oxidative stress and hepatotoxicity using a mouse model. We used two control groups: group A was given

The antioxidant activities of alpha-hederin and hederasaponin-C from Hedera helix, and hederacolchisides-E and -F from Hedera colchica were investigated, in this study. The antioxidant properties of the saponins were evaluated using different antioxidant tests: 1,1-di-phenyl-2-picryl-hydrazyl

The antioxidant activity of a triterpenoid glycoside [3-O-(beta-D-glucopyranosyl)-hederagenin; OGH] isolated from the berries of Hedera colchica, an ivy species endemic in Georgia, was investigated. The antioxidant properties of OGH were evaluated using different antioxidant assays:

OBJECTIVE This study was aimed to evaluate the effect of Hedera nepalensis crude extract (HNC) and its isolated compound lupeol on antioxidant defence system, biochemical parameters and behavioural indices of Alzheimer disease generated in diabetic rats. METHODS To evaluate the effect of the plant

This study was designed to examine the total phenolic and flavonoid contents, radical scavenging and antibacterial activity of the ethanolic extracts from leaves, berries and stems of Hedera pastuchovii Woron. ex Grossh. The berry extract, which contained the highest phenolic and flavonoid

α-hederin, a saponin that is a major constituent of English Ivy (Hedera helix) is effective in the treatment of asthma. In the present study, the effect of α-hederin on lung tissue pathology and the levels of the inflammatory mediators; IL-2 mRNA, IL-17 mRNA, and MicroRNAs (miRNA)-133a was evaluated
