Momordica charantia L. (cucurbitaceae), is a plant whose fruits are widely consumed in Chad. Seeds, green and ripe pulps of the this were subject study. The total polyphenols, antioxidants, flavonoids anthocyanins evaluated by Folin - Ciocalteu, DPPH, iron trichloride pH-differential methods respectively. polyphenol obtained 9.368 mg GAE/g for seeds extract, 9.068 pulp extract 8.505 mature extr...

Although interspecific hybrids between cyclamen (Cyclamen persicum) cultivars and C. purpurascens were produced by using the ovule culture, mode of inheritance of flower pigment remains obscure. Therefore, inheritance of anthocyanin in the petals in the crosses between diploid cyclamen cultivars and C. purpurascens was investigated in the present study. In every cross combination, including the...

Polyphenols contained within plant tissues are consumed in significant amounts in the human diet and are known to influence a number of biological processes. This study investigated the effects of an anthocyanin-rich berry-extract on glucose uptake by human intestinal Caco-2 cells. Acute exposure (15 min) to berry extract (0.125%, w/v) significantly decreased both sodium-dependent (Total uptake...

The present study provides an in-depth characterisation of the non-anthocyanin and anthocyanin phenolic compounds potato peels from ten coloured varieties. Furthermore, underexplored bioactive potential (antioxidant, cytotoxic anti-inflammatory capacities) studied is comprehensively analysed. Among phenolics, caffeic a caffeoylquinic acid were found in highest concentrations all samples, which ...

Dietary anthocyanins may slow cognitive decline, improve performance and exert neuroprotective effects against neurodegenerative disorders. However, the underlying mechanisms of their action are not fully understood. This study investigated 12-week anthocyanin-rich bilberry extract supplementation (0.02%) on global gene expression in hippocampus ApoE-/- mice to help understanding molecular anth...

The Lc petunia system, which displays enhanced, light-induced vegetative pigmentation, was used to investigate how high light affects anthocyanin biosynthesis, and to assess the effects of anthocyanin pigmentation upon photosynthesis. Lc petunia plants displayed intense purple anthocyanin pigmentation throughout the leaves and stems when grown under high-light conditions, yet remain acyanic whe...

Anthocyanin biosynthesis is one of the most thoroughly studied enzymatic pathways in biology, but little is known about the molecular mechanisms of its final stage: the transport of the anthocyanin pigment into the vacuole. We have identified a multidrug resistance-associated protein (MRP), ZmMrp3, that is required for this transport process in maize (Zea mays). ZmMrp3 expression is controlled ...

Purpose: To evaluate the mechanism of antioxidant activity of the methanol extract of Codonopsis pilosula. Methods: Anti-oxidative properties were assessed by measuring free radical scavenging activity, nitric oxide (NO) levels, protein oxidation and reducing power, while the mechanism of antioxidative effect of Codonopsis pilosula extract was determined by measuring iNOS and COX-2 expression i...

We investigated the role of transcription factors (R, SN, C1, and PL) in the regulation of anthocyanin biosynthesis by different light qualities (white, red, blue, and ultraviolet) and by cytokinin in maize (Zea mays). We analyzed anthocyanin accumulation, structural gene expression, and regulatory gene expression in the seed aleurone and the seedling mesocotyl. In the mesocotyl, white, blue, a...
