Isoquercetin is a flavonoid, a type of chemical compound. It is the 3-O-glucoside of quercetin. Isoquercetin can be isolated from various plant species including Mangifera indica (mango)[1] and Rheum nobile (the Noble rhubarb). It is also present in the leaves of Annona squamosa and Camellia sinensis (tea).[2][3]
Spectral data
The lambda-max for isoquercetin is 254.8 and 352.6 nm.
Potential clinical uses
Isoquercetin is presently being investigated for prevention of Thromboembolism in selected cancer patients (NCT02195232) and as an anti-fatigue agent in kidney cancer patients treated with sunitinib (NCT02446795).
