in many field observation, ecological equipment, phenology and ethnopharmacological data of achillea millefolium l. and a. micrantha wild. were studied. the inflorescences of plants were collected in different locations of golestan province: chaharbagh (2000 m) and dozan (2200 m) respectively. essential oils were obtained by steam distillation (clevenger) and analyzed by gas chromatography-mass...

Peganum harmala L. (Zygophyllaceae) is one of the most important medicinal plants had been used in traditional medicine in North of Iran as anti parasite, anti inflammatiom, anti tumor and anti infection. The aim of this study was to evaluate of ecological factors , ethno pharmacology and record of the relationship between secondary metabolites content and their antioxidant activity in seeds ex...

Response surface methodology was applied to optimization of the conditions for reflux extraction of Pandan (Pandanus amaryllifolius Roxb.) in order to achieve a high content of total flavonoids (TF), total phenolics (TP), and high antioxidant capacity (AC) in the extracts. Central composite experimental design with three factors and three levels was employed to consider the effects of the opera...

Natural antioxidants have an important role against damage by ROS. This research had been carried out about ecological characters, phytochemical and antioxidant activity of Capparis spinosa L. in Semnan and Golestan province. So in much field observation, different parts of C.spinosa were collected from two natural habitats in Golestan (200 m) and Semnan province (2100 m) during August to Septe...

A split plot 3 by 4 experiment was designed to examine the impact of 15-week variable levels of nitrogen fertilization (0, 90, 180 and 270 kg N/ha) on the characteristics of total flavonoids (TF), total phenolics (TP), total non structurable carbohydrate (TNC), net assimilation rate, leaf chlorophyll content, carbon to nitrogen ratio (C/N), phenyl alanine lyase activity (PAL) and protein conten...

Water solutions of extracts were investigated for total phenol content, flavonoid content and antioxidant activity. Susceptibility to degradation of water solutions of plant extracts, under light and in the dark, during storage at room temperature was investigated in order to determine their stability prior to their application for fortification of food products. Large dispersion of total pheno...

BACKGROUND Numerous popular media sources have developed lists of "Super Foods" and, more recently, "Super Fruits". Such distinctions often are based on the antioxidant capacity and content of naturally occurring compounds such as polyphenols within those whole fruits or juices of the fruit which may be linked to potential health benefits. Cocoa powder and chocolate are made from an extract of ...

The biologically active compounds in wine, especially phenolics, are responsible for reduced risk of developing chronic diseases (cardiovascular disease, cancer, diabetes, etc.), due to their antioxidant activities. We determined the contents of total phenolics (TP) and total flavonoids (TF) in selected Serbian white wines by colorimetric methods. Total antioxidant activity (TAA) of the white w...

The effect of two different CO(2) concentrations (400 and 800 μmol mol(-1)) on the photosynthesis rate, primary and secondary metabolite syntheses and the antioxidant activities of the leaves, stems and rhizomes of two Zingiber officinale varieties (Halia Bentong and Halia Bara) were assessed in an effort to compare and validate the medicinal potential of the subterranean part of the young ging...
