Abstract Flavonoids play important roles in regulating plant growth and development. In this study, three kaempferol 3- O -glycosides were identified mainly accumulated flowers but not leaves or fruits of Malus . , flower petal color is normally white, some genotypes have red containing anthocyanin. Anthocyanin biosynthesis appears to be competition with production controlled by the biosynthetic genes. The white had better-developed seeds than genotypes. flowers, overexpression MYB10...
The antioxidant capacity (AC) and activity (AA) of three flavonols (FLV), aglycones their glycosylated derivatives were evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays in various solvents. Findings confirmed that the glycosylation at 3-position (3-glycosylation) always decreased AC under most conditions due to substitution hydroxyl group glycoside disruption molecular planarity. 7-glycosylated did not have above...
The polyphenols anthocyanins and their aglycones, anthocyanidins, can control postprandial blood glucose through inhibition of α-amylase. In this study, 10 were purified from fruit materials 6 anthocyanidins obtained by acid hydrolysis. identities these compounds confirmed LC-ESI-MS/MS. Inhibition activities on α-amylase higher than those anthocyanins. kinetic assay using 2-chloro-4-nitrophenyl α-maltotrioside detection properties in the composition starch digestion products revealed that an...
Epidemics of obesity and type 2 diabetes drive strong consumer interest in plant-based low-calorie sweeteners. Trilobatin is a sweetener found at high concentrations the leaves range crabapple (Malus) species, but not domesticated apple (Malus × domestica) leaves, which contain trilobatin's bitter positional isomer phloridzin. Variation trilobatin content was mapped to locus on LG 7 segregating population developed from cross between apples crabapples. Phloretin glycosyltransferase2 (PGT2)...
Dihydrochalcones in<italic>Malus</italic>had excellent antibacterial activity against both Gram-positive and Gram-negative bacteria.
To explore the inhibitory activity of polyphenols on α-glucosidase and α-amylase, 16 were isolated, identified, quantified in an edible Malus "Winter Red" crabapple fruit. The limitations two traditional methods for α-amylase assay vitro assayed. An improved method based HPLC a colorimetric coupled with custom-made mini-column established. Compared positive controls, acarbose miglito, most polyphenols, especially four aglycones (cyanidin, quercetin, phloretin, 3-hydroxyphloretin) showed...
