The present investigation has been carried out to determine the proximate composition, amino acids, metal contents, oil composition as well as the antioxidant capacity of the seeds of Ipomoea hederacea Jacq. and Lepidium sativum L. Proximate composition indicated a great difference in oil (14.09 ± 0.66, 28.03 ± 1.05) and fibre (16.55 ± 0.31, 6.75 ± 1.20) contents for I. hederacea and L. sativum...

Antioxidants have reactive oxygen species (ROS) scavenging ability with great relevance in the prevention of oxidative stress. The present study aimed to examine the antioxidant and ROS scavenging activities of 70% methanolic extract of Tinospora cordifolia. The plant was found a significant source of carbohydrate, alkaloid, ascorbic acid, tannin, phenolic and flavonoid compound. The extract wa...

Extraction procedure was standardized and for the soluble, glycoside, and wall-bound fractions of phenolic acids from Vetiveria zizanioides. The water soluble alkaline extract which represents the cell wall-bound fraction contained the highest amount of phenolic acids (2.62 ± 1.2 μM/g fwt GA equivalents). Increased phenolic content in the cell wall indicates more lignin deposition which has an ...

This article reports experimental data related to the research article entitled "Different effectiveness of two pastas supplemented with either lipophilic or hydrophilic/phenolic antioxidants in affecting serum as evaluated by the novel Antioxidant/Oxidant Balance approach" (M.N. Laus, M. Soccio, M. Alfarano, A. Pasqualone, M.S. Lenucci, G. Di Miceli, D. Pastore, 2016) [1]. Antioxidant status o...

Our objective was to investigate the cross-sectional association between sleep duration and biomarkers of oxidative stress (glutathione (GSH), glutathione peroxidase (GSH-Px), vitamin C, thiobarbituric acid reactive substances (TBARS), and trolox equivalent antioxidant capacity (TEAC)) among police officers. Standardized techniques were used to analyze biomarkers in fasting blood specimens. Mea...

This study reports in vitro lipophilic antioxidant, inhibition of α-amylase and antibacterial activities of extracts of peel and pulp of citrus samples from Aceh, Indonesia. HPLC (high-performance liquid chromatography), phytochemical, and FTIR (fourier transform infrared) analysis detected carotenoids, flavonoids, phenolic acids and terpenoids, contributing to the biological potencies. Most pe...

The antioxidant activity and total phenolic content of some spices (M. piperita L., R. coriaria L., T. spicata, S. officinalis, R. officinalis L., C. ovata L., O. vulgare L., L. nobilis L. and C. annum L.) were determined. The higher TEAC values (mmol TE/g extract) were obtained for sage (1.783) and rosemary (1.241). The IC value (mg/ml) ranged between 0.103-4.082 for mint and capers, respectiv...

BACKGROUND: The conventional solution-phase Chemical Cleavage of Mismatch (CCM) method is time-consuming, as the protocol requires purification of DNA after each reaction step. This paper describes a new version of CCM to overcome this problem by immobilizing DNA on silica solid supports. RESULTS: DNA test samples were loaded on to silica beads and the DNA bound to the solid supports underwent ...

The aim of this study was to describe behaviour, kinetics, time courses and limitations of the six different fully automated spectrometric methods--DPPH, TEAC, FRAP, DMPD, Free Radicals and Blue CrO5. Absorption curves were measured and absorbance maxima were found. All methods were calibrated using the standard compounds Trolox® and/or gallic acid. Calibration curves were determined (relative ...
