Leafs have contain wide antioxidant range which may provide prevention against radical oxygen species. The aim of this work was to measure the antioxidant capacity of 15 commercially available leaf extracts (ethanol, methanol, water) using ferric reducing antioxidant power (FRAP) assay and trolox equivalent antioxidant capacity (TEAC) assay. Also we evaluated total phenolic and monomeric anthoc...

The paper presents the antioxidant activity evaluation of Silybum marianum L. extract in comparison with the commercial silymarin standard solution (2 mg/mL) and the time-dependent antioxidant capacity by calculating the free radical 2,2-diphenyl-1-pycryl-hydrazyl (DPPH) reaction rate in the presence of these biosystems. The best result was obtained in the case of S. marianum L. extract, with a...

the main souroe.i) Some reseachers2} reported that diverse compounds naturally occurring in food can exert an antimutagenic effect due to their antioxidant capacity. According to our previous works,3'S) methanolic extracts of peanut hutls (MEPH) have both strong antioxidant activity as a result of large amounts of total phenolic compounds, and properties of scavenging freeradical and active-oxy...

The methanol, ethanol and petroleum ether soluble crude and fractions extract of Gliricidia sepium and Spathodea campanulata leaf were examined for antibacterial activities, phytochemicals and possible sources of antioxidant. The antibacterial activity of the crude and fractions were carried out against nine clinical bacteria isolates using the agar well and disc diffusion methods respectively....

The present paper aims at reviewing and commenting on the analytical methods applied to antioxidant and antioxidant capacity assessment in plant-derived products. Aspects related to oxidative stress, reactive oxidative species' influence on key biomolecules, and antioxidant benefits and modalities of action are discussed. Also, the oxidant-antioxidant balance is critically discussed. The conven...

Oxidative stress can damage cellular components including DNA, proteins or lipids, and may cause several skin diseases. To protect from this damage and addressing consumer's appeal to natural products, antioxidants obtained from algal and vegetal extracts are being proposed as antioxidants to be incorporated into formulations. Thus, the development of reliable, quick and economic in vitro metho...

Light is one of most important factors to plants because it is necessary for photosynthesis. In this study, physiological and gene expression analyses under different light intensities were performed in the seedlings of rubber tree (Hevea brasiliensis) clone GT1. When light intensity increased from 20 to 1000 µmol m(-2) s(-1), there was no effect on the maximal quantum yield of photosystem II (...

Paracetamol (acetaminophen, PCM) is a widely used over-the-counter analgesic and antipyretic drug. Intake of a large dose of PCM may result in severe hepatic necrosis. Oxidative stress is mediated by oxidative capacities of the PCM metabolite (N-acetyl-para-benzo quinoneimine, NAPQI), which covalently binds to proteins and other macromolecules to cause cellular damage. At low doses, NAPQI is ...
