Phenolic compounds were extracted from three wild grapevine species: Vitis californica, V. riparia and V. amurensis seeds using 80% methanol or 80% acetone. The total content of phenolic compounds was determined utilizing the Folin-Ciocalteu's phenol reagent while the content of tannins was assayed with the vanillin and BSA precipitation methods. Additionally, the DPPH free radical scavenging a...

objective: the inoculation of substrates with arbuscular mycorrhizal fungi (amf) is one of the most important effective strategies applied and one of the aims of sustainable agriculture. methods: this experiment was conducted to evaluate the effects of amf inoculation (0, 2.5, and 5 w/w) on morpho-physiological traits such as flower and root dry weight, water-use efficiency and antioxidant capa...

background & aim: fruits from the jujube plant (ziziphus jujuba) possess health-promoting effects and medicinal properties. jujube has a long history of usage as a remedy in iranian traditional medicine and is recommended for the treatment of some diseases. this study investigated the variations in antioxidant capacities (aox), total phenol (tph), total flavonoid (tf) and total anthocyanin ...

background: plants and their phytochemicals have immense potential for the management of different types of wound. salvia multicaulis vahl. is an evergreen shrub species, which traditionally used as a wound healing agent. objective: the aim of the present study is to evaluate phytochemicals and wound healing activity of s. multicaulis in an excision wound model. methods: preliminary phytochemic...

abstract having no exact knowledge of most appropriate harvesting time in kiwifruit grown in different regions of guilan province, as well as the low storage longevity of the fruits are the most important factors causing considerable reduction in both marketability and export affairs. in this study, the influence of fruit quality in term of harvesting time on the postharvest quality and food va...

tomato seedlings were inoculated with t. harzianum bi (106 spores/ml) and salicylic acid (5mm) other separately or combined together in the greenhouse environment. the effect of salicylic acid was investigated on growth of antagonistic agent in vitro. for an investigation of the effect of salicylic acid and of antagonist on pathogenecity factor, treatment with t. harzianum bi by drenching soil ...

Phenols (aromatic organic compounds) are commonly occurring organic pollutants in the environment. Some of the toxic effects of phenol in humans are corrosive to eyes, skin and respiratory track, in addition also causes lethal effects in animal and plant community when discharged even in low concentrations. The problem associated with phenol in the environment, is in need to removal such hazard...

Since they often inhibit abundant bacteriological populations in municipal wastewater treatment plants, alternative treatment methods should be investigated – including advanced oxidation processes. This paper studies the degradation of three representatives of phenolic compounds using the Fenton system in the presence of chlorides and sulfates: phenol, 2-chlorophenol and 2-nitrophenol. The pre...
