BACKGROUND Anthocyanins have been shown to improve endothelial function in animal models. However, whether these compounds have similar beneficial effects in humans is largely unknown. METHODS In a short-term crossover study, 12 hypercholesterolemic individuals were given oral anthocyanins (320 mg) isolated from berries or placebo. Brachial artery flow-mediated dilation (FMD) was assessed bef...

CONTEXT Melanin plays an important role in preventing ultraviolet (UV) light-induced skin damage. Overexposure to UV radiation can lead to the formation of free radicals and trigger inflammation and hyperpigmentation of the skin. Anthocyanin can combat excessive free radicals in the body and can reduce the occurrence of inflammation. However, anthocyanin molecules are unstable and highly suscep...

Anthocyanin synthesis, hair formation, and the synthesis of ascorbic acid oxidase are all phytochrome-mediated reactions occurring in the hypocotyl of mustard (Sinapis alba L.), controlled by phytochrome actually located in the hypocotyl. A comparison of these three reactions showed that in certain respects they differ greatly in their response to light. The ability of the seedling to respond t...

Climatic conditions and soil type have significant influence on grape ripening and wine quality. The reported study was conducted in two "Cabernet Sauvignon (Vitis vinifera L.V)" vineyards located in Xinjiang, a semiarid wine-producing region of China during two vintages (2011 and 2012). The results indicate that soil and climate affected berry growth and anthocyanin profiles. These two localit...

Anthocyanins are flavonoid compounds responsible for red/purple colors in the leaves, fruit, and flowers of many plant species. They are produced through a multistep pathway that is controlled by MYB transcription factors. VvMYBA1 and VvMYBA2 activate anthocyanin biosynthesis in grapevine (Vitis vinifera) and are nonfunctional in white grapevine cultivars. In this study, transgenic grapevines w...

Phenolics, anthocyanin and alpha-bisabolol production from poplar (Populus delotides) in tissue culture was determined. A number of phenolic acids were identified by HPLC. PAL activity in response to phytohormones, cells growth and anthocyanin production showed a positive correlation. A component, alpha-bisabolol, was identified using gas chromatography and UV spectroscopy. In vitro production ...

Kinetin induces formation of red pigment in seedlings of Amaranthus retroflexus in the dark. This effect is similar to the light-induced formation of pigment. Light and kinetin do not act in a simple additive way. The pigment is not an anthocyanin, and its formation is not affected by inhibitors of anthocyanin formation.

melissa officinalis l. is a well-known medicinal plant from the family of lamiaceae. the plant is high in flavonoid. flavonoids of lemon balm such as rosmarinic acid and anthocyanin have an antiviral and antioxidant effect. micronutrients are the element that is necessary for the plant in low concentration. in this experiment the effect of micronutrient (fe and zn) was examined on the anthocyan...

Flavonoids represent a large class of secondary plant metabolites, of which anthocyanins are the most conspicuous class, dueto the wide range of colors resulting from their synthesis. Anthocyanins are important to many diverse functions within plants. Synthesis of anthocyanins in petals is undoubtedly intended to attract pollinators, whereas anthocyanin synthesis in seeds and fruits may aid in ...
