an investigation of potential sources of nutraceuticals from,1. introduction. oxidative stress is associated with a number of diseases and arises as a consequence of an imbalance between reactive oxygen species (ros), reactive nitrogen species (rns), and their dissipation via enzymatic and non-enzymatic mechanisms [ 1 ].
overwhelming literature reports have indicated varying degrees of antioxidant efficacies of extracts from nigerian medicinal plants in comparison to synthetic antioxidants. these efficacies were analyzed to provide insight into the strength of antioxidant activity.
anticancer activity of nigerian medicinal plants Rubber Auxiliary Agent
the antioxidant and anti-inflammatory activity of c. longa makes it a suppressor of breast, colon, lung and liver cancer cells. curcumin has also shown obstructive activity against cancer cell signaling phases .
short overview of some assays for the measurement of,some of the most common antioxidant assays based on scavenging activity include orac, dpph, 2,2′-azinobis-(3-ethylbenzothiazole-6-sulphonate) (abts)/teac assay and n,n-dimethyl-p-phenylenediamine radical scavenging (dmpd) assay [31,32].
antioxidant activity and phytochemical contents of some
ten plants which are used as condiments, spices, herbs, and eaten raw in nigeria were investigated for their antioxidant activities using 2, 2-diphenyl-1-picrylhydrazyl (dpph) method....
analytical methods used in determining antioxidant activity,two antioxidant activity tests, including the analysis of the cation radical (abts) and the analysis of the reducing antioxidant capacity of the cupric ion (cuprac), as well as a test for the total phenolic content, the folin–ciocalteu test (fc), were used at the same time.

dmpd assay for antioxidant activity g-biosciences,reviews. coa. antioxidant capacity is an overall ability of organisms or food to catch free radicals and prevent their harmful effect. antioxidative effect includes protection of cells and cellular structures against harmful effect of free radicals, especially oxygen and nitrogen. substances with antioxidative properties are called antioxidants.
antioxidants from nigerian medicinal plants: what are the
evaluation of antioxidant activity including the oxygen radical absorbance capacity (orac), total radical-trapping antioxidant potential (trap), total oxidant scav-enging capacity (tosc), chemiluminescence (cl), croton bleaching, low density lipoprotein (ldl) oxidation, ferric reducing antioxidant power (frap), copper
fully automated spectrometric protocols for determination of,the study resulted in the optimization, automation and precise description of protocols of six photometric methods, namely the dpph, teac, frap, dmpd, free radicals kit and blue cro 5 assays, which cand be used for the determination of antioxidant activity.
- Can DMSO be used in microwave assisted extraction of total phenolic compounds?
- The study reported the first time that DMSO was employed and optimised for microwave assisted extraction of total phenolic compounds from chilli samples and for their antioxidant assay. The spectrophotometric method for analysis of both antioxidant activity and total phenolics were conducted.
- Does DMSO extract increase antioxidant activity?
- The DMSO extract shows significantly the higest value of in vitro antioxidant activity compared with other common solvent used. Quantification of the total phenolic compounds are thus helpful in a total evaluation of their antioxidant activity.
- What is the absorbance peak of DMPD +?
- The DMPD ·+ radical shows an absorbance peak at 505 nm (Sripakdee et al. 2015 ). Radical DMPD ·+ was generated from the mixture of 1 mL of 100 mM DMPD, 100 mL of 0.1 M acetate buffer pH 5.25 and 0.4 mL of 0.05 M FeCl 3.
