Description générale

The flavonoid quercetin 3-O-(6-O-malonyl)glucoside, a conjugate of quercetin, was identified in the green-leafed lettuce Lactuca sativum.

Actions biochimiques/physiologiques

Metabolite in flavone and flavonol biosynthesis, is found in plants like the fruit peel of Sicana odorifera and mulberry leaves, shows antioxidant activity. Q3MG also potentially has antiatherogenic protective effects; and found to improve hyperglycemia in obese mice and reduced oxidative stress in the liver.

Conditionnement

Bottomless glass bottle. Contents are inside inserted fused cone.

Ten flavonols and three anthocyanins were identified in the fruit peel of melón de olor (Sicana odorifera), and their structures were established by spectrometric and spectroscopic (ESI-MS and NMR) techniques. One of the identified flavonols, quercetin 3-O-(6''-O-malonyl)-β-D-glucopyranoside 4'-O-β-D-glucopyranoside, has not

Mulberry therapies on type 2 diabetic patients or streptozotocin-induced diabetic rats have been reported to improve fasting blood glucose levels. We investigated the effects of dietary consumption of mulberry-leaf powder and purified quercetin 3-(6-malonylglucoside), the quantitatively major flavonol glycoside in
