conclusions further investigations are needed about favorable composition of unsaturated fatty acids and flavonoid content of leaves of s. paradoxa. in addition, due to high phenolic content of the leaves, s. paradoxa is a promising source of natural antioxidants and may play good antidiabetic activity. results the amount of total phenolic compounds was higher in leaves than roots. besides, roo...

Nowadays, traditional plant study has grown in importance as their use been increased. Tectona grandis (teak) is one of several plants that have studied for its phytochemical and pharmacological properties. This includes a number secondary metabolites, which may explain diverse Although teak leaf compounds examined the past, there still little information on diversity compounds. As result, we a...

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...

The effect of variation of harvest season and cultivar on the total phenolic content (TPC), total flavonoid content (TFC), HPLC-UV/DAD profile and antioxidant properties in Vaccinium ashei (Rabbiteye blueberry) leaves grown in Brazil was evaluated. The cultivars collected in December and March were Aliceblue, Powderblue, Climax, Bluegem and FloridaM. It was observed that leaves from March had t...

Hymenocallis littoralis has allelochemical importance such as defensive compounds, insect repellents, attractants, and their role in ecological balance. Antioxidant activities of Hymenocallis littoralis bulb, anther, flower, stem, leaves and root methanolic extracts were evaluated using Ferric Reducing Antioxdiant Power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH), total phenolic and flavonoid ...

Twenty-six different wild blackberry leaf samples were harvested from various localities throughout southeastern Poland. Leaf samples were assessed regarding their phenolic compound profiles and contents by LC/MS QTOF, and their antioxidant activity by ABTS and FRAP. Thirty-three phenolic compounds were detected (15 flavonols, 13 hydroxycinnamic acids, three ellagic acid derivatives and two fla...

Modern and sustainable production of safe and healthy high quality vegetables for human consumption is nowadays the goal of many producers. Chicory (Cichorium intybus L.) has become an important crop used as food in many countries over the past decade. In this work fi eld and glasshouse trials were conducted to compare phenolic profi les of hydroponically forced leaves and leaves produced as co...

The bioactive compounds and antioxidant activity of aronia leaves at different stages of maturity were identified and evaluated. Young and old leaves were approximately 2 months of age and 4 months of age, respectively. The young leaves contained more polyphenols and flavonoids than the old leaves. Three phenolic compounds (i.e., chlorogenic acid, p-coumaric acid, and rutin) were detected by HP...

A rapid method has been developed for the quantitative estimation of β-sitosterol, total phenolic and flavonoid compounds present in the leaves of Moringa oleifera Lam. (Family: Moringaceae). The hydroalcoholic extract of the leaves was subjected for the quantitative estimation of these compounds. The hydroalcoholic extract of the leaves of Moringa oleifera was prepared by the process of cold m...

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...
