Several complex phenotypic changes are induced when the transcription factor AmMYB308 is overexpressed in transgenic tobacco plants. We have previously shown that the primary effect of this transcription factor is to inhibit phenolic acid metabolism. In the plants that we produced, two morphological features were prominent: abnormal leaf palisade development and induction of premature cell deat...

Phenolic compounds like phenolic acids, flavonoids and tannins are important plant metabolites that are important for many pharmacological activites.we had earlier demonstrated the wound healing activity, analgesic and anti inflammatory of the methanolic extract. The extract was investigated to determine the nature of the phytoconstituents responsible for these activities and this led to the is...

Types of nettles (Urtica dioica) were collected from different regions to analyze phenolic compounds in this research. Nettles are specially grown in the coastal part. According to this kind of properties, nettle samples were collected from coastal part of (Mediterranean, Aegean, Black sea, and Marmara) Turkey. Phenolic profile, total phenol compounds, and antioxidant activities of nettle sampl...

Phenolic profiles and antioxidant properties of purple wheat varieties were investigated to document the effects of bread-making. Bread crust and crumb along with samples collected after mixing, 30 min fermenting, 65 min fermenting, and baking were examined. Free phenolic content (105.4 to 113.2 mg FAE/100 g) significantly (p < 0.05) increased during mixing, fermenting, and baking (65% to 68%)....

The phenolic compounds in fruits are secondary plant metabolites and are mainly associated with the nutritional as well as the sensorial properties of fruits. These compounds not only affect the aroma of the fruits, but are also found to have profound effects on human health due to their antioxidant, anti-inflammatory and antimicrobial effects. Berry fruits, including blueberry, cranberry, rasp...

Phenolic compounds, ubiquitous in plants are an essential part of the human diet, and are of considerable interest due to their antioxidant properties. These compounds posses an aromatic ring bearing one or more hydroxyl groups and their structures may range from that of a simple phenolic molecule to that of a complex high-molecular weight polymer. Flavonoids, which bear the C6– C3–C6 structure...

Cichoric acid is the main phenolic compound in the root and rhizome of the medicinal part, Echinacea purpurea that is known for possessing immune enhancing characteristics. In this study, we analysis the the synthesis and storage sites of phenolic compound in E. purpurea. We used fluorescent microscopy, transmission electron microscopy, cytochemical and immunocytochemical localization to observ...

Fruit and vegetable intake is inversely correlated with risks for several chronic diseases in humans. Phytochemicals, and in particular, phenolic compounds, present in plant foods may be partly responsible for these health benefits through a variety of mechanisms. Since environmental factors play a role in a plant's production of secondary metabolites, it was hypothesized that an organic agricu...

Some dried citrus peels, more familiar as chenpi in China, have been widely used in traditional Chinese medicines from ancient times. This paper reports the efficiency of infusion cooking on extracting minerals and phenolic compounds (flavanone glycosides [FGs], polymethoxylated flavones [PMFs], and phenolic acids), and also antioxidant activity of hot water extract of citrus peels. Peels of 2 ...

This study evaluated the efficacy of various organic solvents (80% acetone, 80% ethanol, 80% methanol) and distilled water for extracting antioxidant phenolic compounds from turmeric, curry leaf, torch ginger and lemon grass extracts. They were analyzed regarding the total phenol and flavonoid contents, antioxidant activity and concentration of some phenolic compounds. Antioxidant activity was ...
