The total antioxidant capacities (TAC) of feces of mammalian herbivores and carnivores were compared. TAC were estimated using three different methods: 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical (ABTS*) reduction, 1,1-diphenyl-2-picrylhydrazyl radical (DPPH*) reduction, and ferric reducing antioxidant power (FRAP). TAC of 18 herbivorous species were generally higher with res...

In this study, antioxidant and antimicrobial potentials of Usnea intermedia, U. filipendula, and U. fulvoreagens and their stictic and usnic acid contents were investigated. Antioxidant activity and total phenolic contents were evaluated in acetone, ethanol, and methanol extracts of these three species. Antioxidant activity was measured by ABTS [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic...

Honey has long been used as a food and reported to have potential health benefits. In this work, total phenol content, colour antioxidant hepatoprotective activities of honey samples different floral origins from the State Hidalgo, Mexico were explored using in vitro assays. Hepatoprotective activity was measured by inhibitition β-glucuronidase; gastroprotective determined inhibition urease; ev...

Athrixia phylicoides, an indigenous South African herbal tea, has potential as a source of nutraceutical antioxidant extracts. Countercurrent chromatography (CCC) was employed as part of a multi-step process to isolate one of the major antioxidant compounds in A. phylicoides extracts. Antioxidant activity of the extracts was comparable to commercial nutraceutical extracts from Aspalathus linear...

Sarcosine is currently one of the most discussed markers of prostate cancer. It is involved in amino acid metabolism and methylation processes that occur during the progression of prostate cancer. In this study, we monitored the effect of the addition of sarcosine (0; 10; 250; 500; 1,000 and 1,500 µM) in a time-dependent manner (0-72 h) on the PC-3 prostate cancer cell line. For the assessment ...

The demand for functional foods and drinks with health benefit is on the increase. The synergistic effect from mixing two or more of such drinks cannot be overemphasized. This study was carried out to formulate and investigate the effects of blends of two or more of pineapple, orange juices, carrot, and Hibiscus sabdariffa extracts (HSE) on the antioxidant properties of the juice formulations i...

In the present study, sawdust bio-oil (SBO) manufactured by fast pyrolysis of Japanese red pine (Pinus densiflora Siebold and Zucc.) sawdust was analyzed for its volatile chemical compound composition and evaluated for its free radical scavenging potential, inhibition of lipid peroxidation and reducing power. Gas chromatography and mass spectroscopy revealed 29 volatile compounds, comprising 97...

In this study, bioactive peptides were produced by enzymatic hydrolysis of casein protein with trypsin (pH = 8). The hydrolysates analyzed for the degree (DH) and antioxidant activities, viz. 2, 2′-diphenyl-1picrylhydrazyl (DPPH), ferric reducing power (FRAP), 3-ethylbenzthiazoline-6-sulphonic acid (ABTS) assay at three temperatures 40, 50, 60°C 4, 5, 6 hours. Also, antimicrobial activity exper...
