Traditional plants contain various secondary metabolites such as alkaloids, terpenoids, steroids and phenolic compounds which have shown antioxidant activities that include scavenging free radical species and inhibiting the production of reactive species resulting from normal cell metabolism. The present study was undertaken to analyse the thin layer chromatography and antioxidant activities of...

it has been investigated the in vitro antioxidant properties of ethanol extracts of the contained-allantoin plants in this study. contained-allantoined plant samples plantago lanceolata, plantago major, robinia pseudoacacia, platanus orientalis and aesculus hippocastanum were tested at different concentrations. the antioxidant activities of plant samples were analysed by 1,1- diphenyl-2-picrylh...

Bioactive compounds and antioxidant capacities of “Phulae” and “Nanglae” pineapple (Ananas comosus L. Merr) which are important geographical indications of Chiang Rai, Thailand were investigated. Two pineapple varieties were collected at 20-40 % yellow peel colour. Total soluble solids (TSS), titratable acidity (TA), total polyphenols, β-carotene, vitamin C and antioxidant capacity (ferric redu...

Five antioxidant and two oxidative stress assays were applied to serum samples of 43 healthy males. The antioxidant tests showed different inter-assay correlations. A very good correlation of 0.807 was observed between the ferric reducing ability of plasma (FRAP) and total antioxidant status (TAS) assay and also a fair correlation of 0.501 between the biological antioxidant potential (BAP) and ...

background & aim: applications of synthetic antioxidant in food have side effects. in present study, the antioxidant potential of morus alba leaves, as natural antioxidant, was screened with cupric ion reducing assay (cuprac assay) and inhibition of lipid peroxidation. the aim of this study was to determine the total antioxidant activity of morus alba leaves. martial & methods: the fir...

In the present study, the antioxidant and antiplasmodial activities of bergenin was compared with its natural derivative 11-O-galloylbergenin for the first time. Both compounds were isolated from Bergenia ligulata. 11-O-galloylbergenin was found to be very active in in-vitro antioxidant assay as compared to bergenin, which was found to be almost inactive. The EC50 values of 11-O-galloylbergenin...

BACKGROUND The use of plants and their derived substances increases day by day for the discovery of therapeutic agents owing to their versatile applications. Current research is directed towards finding naturally-occurring antioxidants having anticancer properties from plant origin since oxidants play a crucial role in developing various human diseases. The present study was designed to investi...

Cornus species fruits are well known as a rich source of antioxidant compounds responsible for their diverse health benefits. The present study aims to investigate the variation of the total antioxidant capacity of Cornelian cherry (Cornus mas L.) fruits during storage, using high-performance thin-layer chromatography (HPTLC) and two spectrophotometric assays based on different mechanisms: the ...
