backgrounds and objective: kombucha is a several thousand years old traditional fermented beverage originated from east. while black tea infusion is the common substrate for preparing kombucha, other herbal infusions can be applied for this reason too. common medicinal herbs or even waste herbal materials, like banana peel, could be suitable substrates for preparing kombucha analogues. in this ...

phenolic and flavonoid compounds are secondary metabolites of plants which possess various activities such as anti-inflammatory, analgesic, anti-diabetes and anticancer effects. it has been established that these compounds can scavenge free radicals produced in the body. because of this ability, not only the plants containing phenolic and flavonoid compounds but also, the pure compounds are use...

objective: antioxidants are considered as the main factors in the inhibition of unwanted oxidation reactions. materials and methods: in this research the antioxidant potential of the fresh fruits of 4 cultivars (a to d) of malus domestica (m. domestica) cultivated in the kashan, qamsar area was evaluated. the antioxidant activity of the samples were evaluated using two complementary antioxidant...

background and objectives:hormozgan province is located in the south of iran, bordering waters of the persian gulf and oman sea. due to the antioxidant potential of plants which might be responsible for their medicinal properties, the antioxidant properties of four medicinal plants of the region were evaluated. methods: the antioxidant properties of chrozophora obliqua, daphne mucronata, salvia...

Types of nettles (Urtica dioica) were collected from different regions to analyze phenolic compounds in this research. Nettles are specially grown in the coastal part. According to this kind of properties, nettle samples were collected from coastal part of (Mediterranean, Aegean, Black sea, and Marmara) Turkey. Phenolic profile, total phenol compounds, and antioxidant activities of nettle sampl...

In our previous study, we have found that persimmon, guava, and sweetsop owned considerably high antioxidant activity and contained high total phenolic contents as well. In order to further supply information on the antibacterial and antioxidant activity of these three tropic fruits, they were extracted by 80% methanol. We then examined the extractions about their phenolic compounds and also st...

Agro-industrial byproducts represent a serious environmental problem and the industries producing these residual materials have incurred expenses for their proper disposal and generally increase the pollution due to the high content of organic substances and might represent legal problems. However, the residues such as grape wastes are potential source of phenolic compounds which are widely kno...

Phenolic compounds are secondary metabolites widely distributed in plants. This study aims to extract the phenolics in Virgin Coconut Oil (VCO) and study its cytotoxic effect on human Hepatocellular Carcinoma (HepG2). Using Fast Blue BB, the crude phenolic extract of VCO yielded 25.54 ppm gallic acid equivalence per 0.5 mg/ml sample. The antioxidant capacity of the phenolic extract gave an IC50...

costus speciosus (koen) j.e. sm. plant and its extracts are used for treatment of fever, snake bites, jaundice, and as a purgative, astringent and antibacterial agent. in the present study, an attempt has been made to evaluate in vitro antioxidant activity of different extracts of this plant by dpph radical scavenging activity, total antioxidant capacity, nitric oxide scavenging activity, ion c...

objective(s): this study aimed to develop drugs from natural sources to overcome the side effects of many of synthetic drugs. methanol extracts of both pericarp and seeds of pleiogynium solandri were used to investigate antioxidant, hepatoprotective, and renal function protective, analgesic, and anti-inflammatory effects and to determine the chemical composition of the extract responsible for b...
