BACKGROUND Phytochemical products have a critical role in the drug discovery process. This promising possibility, however, necessitates the need to confirm their scientific verification before use. Hence, this study aims to evaluate (1) the antioxidant activity, (2) cytotoxicity potential, and (3) the effect on ultrastructural alteration in gastric cancer cell lines through exposure to fraction...

The plants of the genus Salvia synthesize several types of secondary metabolites with antimicrobial, cytotoxic, and radical scavenging activities and are used in the folk medicine of different countries. Eleven Salvia species including S. aegyptiaca, S. aethiopis, S. atropatana, S. eremophila, S. hypoleuca, S. limbata, S. nemorosa, S. santolinifolia, S. sclarea, S. syriaca, and S. xanthocheila ...

The current study was assigned to evaluate the total phenol, total flavonoid content (TPC, TFC) and antioxidant properties of extracts from the aerial parts of Scrophularia frigida (S. frigida). Extracts were also tested by preliminary phytochemical screening as well as cytotoxic activity against Artemia salina, MCF-7 (human breast carcinoma) and SW-480 (colon carcinoma) and L-929 (normal) cell...

The aim of this study was to investigate in vitro antioxidant activity and anti-bacterial activity of the petroleum ether, ethyl acetate and methanol extract obtained from the whole part of Jurinea dolomiaea Boiss (Asteraceae). Total phenolic and flavonoid contents of these extracts were determined as gallic acid and rutin equivalents, respectively. Total antioxidant activity, reducing power of...

Mushrooms are important sources of natural bioactive compounds. Pleurotus eryngii (DC.) Quél is recognized for its organoleptic quality and health effects, being extensively commercialized. Instead, Suillus bellinii (Inzenga) Watling is an ectomycorrhizal symbiont, whose main properties were scarcely reported. Considering current trends, the mycelia and the culture media of these mushrooms migh...

The crude extract contains many compounds along with the various lichen metabolites and it is very difficult to say which compound(s) has the antioxidant potential unless and until it is purified. In the previous Chapter 3 & 4 the biological activities of Usnea ghattensis attributed to the crude extract containing usnic acid and norstictic acid have been presented. In order to know the antioxid...

In the present study experiments were carried out to determine the total phenolic content and their comparative antioxidant activities in relation to phenol content employing Folin-ciocalteu, DPPH, and ABTS assays of the different solvent extracts of the plant S. macrosperma. It was found that on an average, the plant extract with higher levels of phenol content had higher antioxidant activity....

BACKGROUND Antioxidant-rich diets are associated with reduced asthma prevalence in epidemiologic studies. We previously showed that short-term manipulation of antioxidant defenses leads to changes in asthma outcomes. OBJECTIVE The objective was to investigate the effects of a high-antioxidant diet compared with those of a low-antioxidant diet, with or without lycopene supplementation, in asth...
