Seed deterioration is expressed as the loss of viability, vigour and quality during ageing. The major causes seed refer to free radical-mediated lipid peroxidation, enzyme inactivation or protein degradation, disruption cellular membranes damage genetic integrity. Accelerated ageing (AA) a simple method for studying mechanisms over short periods. In order estimate rate, seeds four maize genotyp...

Flavonoids are a group of polyphenolic plant secondary metabolites important for plant biology and human nutrition. In particular flavonols are potent antioxidants, and their dietary intake is correlated with a reduced risk of cardiovascular diseases. Tomato fruit contain only in their peel small amounts of flavonoids, mainly naringenin chalcone and the flavonol rutin, a quercetin glycoside. To...

Anthocyanins are the largest group of water-soluble pigments in the plant kingdom and belong to the family of compounds known as flavonoids. Major sources of anthocyanins are blueberries, cherries, raspberries, strawberries, black currants, purple grapes and red wine. In recent years several studies have shown that anthocyanins display a wide range of biological activities including antioxidant...

Edible flowers are appreciated due to their aesthetic features, nutritional value and antioxidant properties. Tulbaghia simmleri Beauv. (Amaryllidaceae family) characterized by a pleasant garlic taste consumed both as fresh dried products. The aim of this work was assess the effect chilling temperature (+4°C) on visual quality, content, aroma profile T. after two (T2) six (T6) days storage. Col...

The anthocyanin composition, fatty acids, and volatile aromas are important for Cabernet Sauvignon grape quality. This study evaluated the effect of exogenous abscisic acid (ABA) and methyl jasmonate (MeJA) on the anthocyanin composition, fatty acids, lipoxygenase activity, and the volatile compounds of Cabernet Sauvignon grape berries. Exogenous ABA and MeJA improved the content of total antho...

Increased tissue status of the long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFA), eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) is associated with cardiovascular and cognitive benefits. Limited epidemiological and animal data suggest that flavonoids, and specifically anthocyanins, may increase EPA and DHA levels, potentially by increasing their synthesis from the shorter-chain n-...

The effect of calcium silicate, γ-aminobutyric acid (GABA), and their mixture on the adaptation wheat corn to simulated rain has been evaluated in pot experiments. Acid was by watering twice with distilled water acidified sulfuric pH = 2. Test plants were grown a plant growth chamber under controlled conditions temperature, illumination relative humidity for 18 days. physiological state test as...

Flavonoids are a group of natural compounds in plants with versatile health benefits for humans. Grapes are a dietary source of flavonoids and the flavonoid components in grape berries can depend on the grape species and cultivar. In this experiment, proanthocyanidins, flavonols, and anthocyanins were analyzed in Vitis coignetiae and V. ficifolia var. ganebu, wild grapes native to Japan, and co...

The current status of research on anthocyanins, their biological effects in vitro and in vivo and their potential application in human therapy are reviewed. Anthocyanins are a class of compounds belonging to the larger flavonoids class which comprises a subset of the polyphenol class of compounds. Anthocyanins are almost exclusively found in higher plants. Major sources of anthocyanins are blue...
