General description
Quercetin 3-O-α-L-arabinopyranoside was isolated from the leaves of the Ruprechtia polystachya tree. [1]
Biochem/physiol Actions
Plant flavonoid which exhibits antibacterial and antioxidant activities. It shows significantly strong ABTS radical scavenging activity[2], inhibitory activity against urease of quercetin glycosides isolated from Allium cepa and Psidium guajava[3]. It is a potential antiplaque agent against Streptococcus mutans[4].
quercetin 3-O-α-L-arabinopyranoside was shown to inhibit the activity of glucose-6-phosphatase. [1]
