Isorhamnetin 3-sophoroside-7-rhamnoside is a natural flavonol glycoside. Isorhamnetin 3-sophoroside-7-rhamnoside inhibited the growth of harmful microalgae. Isorhamnetin 3-sophoroside-7-rhamnoside is closely related to the convergence of different fruit pups, which is less affected by some known convergent compounds.
Quercetin 3-O-glucoside-7-O-rhamnoside at 30 mg/kg i.p. can decrease the ambulatory locomotor activity and increase the sodium thiopental-induced time of loss of the righting reflex suggesting a clear depressant action.
An anti-oxidative composition containing isorhamnetin-3-glucoside-7-rhamnoside (IGR)isolated from Hippophae rhamnoides L. is provided to ensure antioxidative, antibacterial, and anti-cancer effect.
