In this study we have demonstrated the variations of carbohydrates and phenolic compounds present in the leaves and stems of ‘Kinnow’ mandarin (Citrus reticulata Blanco) trees in alternate bearing cycle and the possible involvement of these compounds to flower bud formation process. The amounts of these compounds were determined in the leaves and stems of “on” and “off” trees  monthly  from Nov...

Background: Artemisia dracunculus L. belongs to the Anthemideae tribe of Asteraceae family. This plant has been used in traditional folk medicine. Also, it's anti-bacterial, anti-fungal, antioxidant, anti-inflammatory and hepatoprotective activity has been proved. Objective: The purpose of this study was to evaluate the antioxidant activity of leaves and inflorescence of A. dracunculus and als...

the genus helichrysum (asteraceae),is comprised of approximately 500-600 species and used for the treatment of a variety of pathological conditions in folk medicine in many countries. in this study, antioxidant activities of aerial parts ofh. pseudoplicatum were investigated employing various in vitro assay systems, i.e. 2,2-diphenyl-1-picrylhydrazyl (dpph) and nitric oxide radical scavenging, ...

objective(s):to optimize the extraction method using response surface methodology, extract the phenolic compounds, and identify the antioxidant and biological properties of stachys parviflora l.  extracts. materials and methods: maceration and ultrasound-assisted extraction (uae) (4, 7, 10 min treatment time, 40, 70, 100 % high-intensity and 60, 80, 100 % (v v-1) methanol purity) were applied t...

The present study aimed at investigating the influence of several production factors, conservation conditions, and extraction procedures on the phenolic compounds and antioxidant activity of blueberries from different cultivars. The experimental data was used to train artificial neural networks, using a feed-forward model, which gave information about the variables affecting the antioxidant...

to determine the phenolic content and antioxidant activity in some native iranian apple cultivars, some five cultivars namely: 'bekran', 'golab-e kermanshah', 'golab-e kohanz' 'golab-e sheikhi' and 'atlasi' were selected and compared with the standard cultivar 'gala'. the profiles related to four phenolic compounds (chlorogenic acid, quercetin-3-galactoside, catechin, and phloridzin) were deter...
