UNLABELLED Objectives : Leaves and flowers of Elaeagnus angustifolia contain phenolic and flavonoid compounds. These compounds have antioxidant properties that protect cells from oxidative damage. The aim of this study was to determine and analyze total phenolic and flavonoid content of leaves and flowers in two E. angustifolia variants using different solvents (ethanol and methanol). MATERIA...

This is the first report to identify the presence of chicoric acid (cichoric acid; also known as dicaffeoyltartaric acid, which is a caffeic acid derivatizedwith tartaric acid) in basil leaves. Rosmarinic acid, chicoric acid and caftaric acid (in the order of most abundant to least; all derivatives of caffeic acid) were identified in fresh basil leaves. Rosmarinic acid was themain phenolic comp...

Yacon (Smallanthus sonchifolius Poepp.) leaves are a potentially rich source of bioactive compounds, such as phenolic acids and flavonoids. In this study, the effect of the extraction method (ohmic-assisted decoction (OH-DE) and decoction (DE)), yacon cultivar (red and white), and leaf age (young and old) on the quality/quantity of extracted phytochemicals were investigated. Extraction yield, e...

The effects of guava leaves extracted using solvents of water, ethanol, methanol, and different concentrations of hydroethanolic solvents on phenolic compounds and flavonoids, and antioxidant properties have been investigated. The antioxidant capability was assessed based on 2,2-diphenyl-1-picrylhydrazyl radical and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical-scavenging abili...

In this study investigated the effect of putrescine sprayed (0.5 & 1mM) on Chamomile (Matricaria chamomilla L.) and the changed of Anthocyanin, Phenolic compounds, POX & CAT Antioxidative enzymes were examined. The results show that Putrescine treatments increased hydrogen peroxide in seedlings to compare control. Phenolic compound content under putrescine treatments are different. Phenolic com...

To elucidate the effects of cultivar and harvest month on the phenolic content and antioxidant activity of mulberry leaves, four major phenolics, including chlorogenic acid (ChA), benzoic acid (BeA), rutin (Rut) and astragalin (Ast), were quantified using an HPLC-UV method. Leaves from six mulberry cultivars, collected from April to October, were analyzed. The antioxidant activity of mulberry l...

Pegagan (Centella asiatica (L.) Urban) is a herbal plant that contain secondary metabolite compounds like phenol and flavonoid. NaCl salinity one of abiotic stress enhanced synthesis some metabolites in plants. This study was investigated the effect to phenolic compound, total flavonoid antioxidant activity pegagan leaves. were treated with five different concentrations, 0 mM (1), 50 (2), 100 (...

The Illyric–Balkan endemic species Moltkia petraea (Tratt.) Griseb. is very interesting as a potential horticultural and medicinal plant. The aim of this study was to investigate soil conditions of M. petraea habitats, the phenolic content in plant parts, and the infl uence of soil properties on the phenolic contents. The results were evaluated using Spearman rank order correlations. Analyzed s...

in order to optimize callus induction in pistacia atlantica desf. subsp. kurdica rech. f., the effect of different plant growth regulator (pgr) combinations were studied. inflorescence axis explants were cultured on wpm medium supplemented with 1, 2 and 3 mg/l of tdz or 1, 2 and 3 mg/l of ba, in combination with 1mg/l different auxins: 2, 4-d,  naa  and iba . callus initiation was observed in a...

Desmodium adscendens plant is widely used as juice or tea in various parts of the world against a wide range of diseases. This study determines the quality and the quantity of polyphenols, flavonoids, anthocyanins, and tannins in D. adscendens leaves by UV-spectrophotometry and RP-HPLC methods. In addition, the antioxidant capacity of these phenolic compounds is evaluated by ABTS (2,2'-azino-bi...
