Background & Aim:Oxidative stresses caused by free radicals are known to promote many diseases such as inflammation and cancer; therefore, any plant product that can inhibit free radical production can play an important role in preventing diseases. We aimed to compare the fracture rate and the scavenging activity of free radicals, and the antioxidant composition of rol...
The present study was carried out to determine the free radical scavenging properties of some plants, found in Malaysia. The air-dried leaves of each plant (20 g) were soaked in distilled water (1:20; w/v) for 72 h at room temperature. Collected supernatants were tested for free radical scavenging activity against the DPPH and superoxide anion radical scavenging assays. All extracts were found ...
The total phenolic content and related total antioxidant capacity of 70 medicinal plant infusions was analyzed. Infusions were prepared in common way in which teas are prepared for human consumption. The total phenolics were measured by Folin–Ciocalteau assay. The total antioxidant capacity was estimated by Ferric Reducing/Antioxidant Power (FRAP) assay. To make practical comparison of relative...
Plants are rich in a variety of chemical compounds. Many are secondary metabolites including aromatic substances most of them are phenols or their oxygen substituted derivatives. Medicinal plants are rich in antioxidant constituents such as phenols, tocopherols, ascorbic acid, carotenoids, and flavonoids etc. They are found to acquire free radical scavenging activity and used worldwide for the ...
Aloe is a genus of medicinal plants with a notable history of medical use. Basic research over the past couple of decades has begun to reveal the extent of Aloe's pharmaceutical potential, particularly against neoplastic disease. This review looks at Aloe, both the genus and the folk medicine, often being called informally "aloes", and delineates their chemistry and anticancer pharmacognosy. St...
Phenolic compounds, especially those with plant origin, constitute an essential part of the human diet due to their antioxidant properties. Antioxidants protect biological systems (nucleic acids, proteins, lipids, lipoproteins) against free radicals and reactive oxygen species. Some medicinal plants contain so high amounts of antioxidants that their use can be considerably effective for human h...

background: thymus daenensis celak. is one of the medicinal plants which cultivated in iran. this plant involve high amount of polyphenols including thymol and carvacrol, which were reported to possess the high antioxidant activity. objective: antioxidative activity (aoa) and chemical constituents of thymus daenensis essential oil (tdeo) were examined. also, the effect of thermal treatments (80...
Lantadenes are pentacyclic triterpenoids present in the leaves of the plant Lantana camara. In the present study, in vitro antioxidant activity and free radical scavenging capacity of lantadene A was evaluated using established in vitro models such as ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picryl-hydrazyl (DPPH•), hydroxyl radical (OH•), nitric oxide radical (NO•), superoxide ...
