D ihydroflavonol 4-reductase from Petunia flowers ca ta ­ lyzes the reduction of d ihydroquercetin to leucocyanidin and , in particular, of dihydrom yricetin to leucodelphinid in , w hereas reduction of the simple dihydroflavonol dihydrokaem pferol to leucopelargonidin could not be observed. This special substra te specificity o f d ihydroflavonol 4-re­ ductase is most p robably the reason for ...

sunburn damage is a physiological disorder, which reducing pomegranate fruits quality and result to huge loss to the gardeners yearly. in this study, the effects of kaolin on maintaining fruit quality and decreasing sunburn damage of malas-e-torsh-e-saveh pomegranate was investigated. processed kaolin (surround® wp) with 0, 2.5, 5 and 10 % (w/v) was sprayed over the whole canopy and fruits at 4...

Two anthocyanins, cyanidin-3-alpha-O-rhamnoside (C3R) and pelargonidin-3-alpha-O-rhamnoside (P3R), and quercitrin (quercetin-3-alpha-O-rhamnoside), were isolated from acerola (Malpighia emarginata DC.) fruit. These polyphenols were evaluated based on the functional properties associated with diabetes mellitus or its complications, that is, on the radical scavenging activity and the inhibitory e...

Anthocyanins are red, purple, or blue plant water-soluble pigments. In the past two decades, anthocyanins have received extensive studies for their anti-oxidative, anti-inflammatory, anti-cancer, anti-obesity, anti-diabetic, and cardioprotective properties. In the present study, anthocyanin biosynthetic enzymes from different plant species were characterized and employed for pathway constructio...

Anthocyanins are naturally occurring reddish pigments that abundant in fruits and vegetables. To investigate the mechanistic basis for the anti-tumor properties of anthocyanins, five aglycone (cyanidin, delphinidin, malvidin, pelargonidin, and peonidin) and four glycosylated (cyanidin-3-glucoside, malvidin-3-glucoside, pelargonidin-3-glucoside and peonidin-3-glucoside) anthocyanins were used to...
