Msr-Ratio (Msr-green) (Msr-green) is a ratiometric fluorescent probe specifically designed for the detection of methionine sulfoxide reductase (MSR) activity.

Chrysophanol 8-O-β-D-(6’-O-galloyl)glucopyranoside, an anthraquinone glucoside, can be isolated from Rheum undulatum L. Chrysophanol 8-O-β-D-(6’-O-galloyl)glucopyranoside has potent DPPH radical and ?O2- scavenging activity.

Spinosin ameliorated memory impairment induced through AβO, the serotonergic neurotransmitter system, and these effects were regulated, in part, through neuroprotective activity via the anti-inflammatory effects of Spinosin.
