Application

Pinobanksin has been used as a reference standard to identify and measure its presence in eleven different acacia honey samples using high-performance liquid chromatography with photo-diode array detection (HPLC-PDA).[1]

Biochem/physiol Actions

Pinobanksin is a potent antioxidant.[2] It displays several anti-cancer properties as an apoptosis inducer, anti-proliferative and antiangiogenic agent in B-cell lymphoma (M12.C3.F6) cells[3] and human umbilical vein endothelial cells[4], respectively. Pinobanksin also exerts antimicrobial and antifungal properties.[5][6]

General description

Pinobanksin is a flavonoid that is widely available in honey and different propolis.[2][3]

The antimutagenicity of 14 naturally occurring flavonoids (20 mumol/l) on ofloxacin (43 mumol/l and 86 mumol/l)-induced bleaching (mutagenicity) was studied in Euglena gracilis. The flavonoids chrysin, techtochrysin, chrysin-5-methylether galangin, galangin-5-methylether, pinocembrin and pinobanksin possess considerable antimutagenic properties against ofloxacin-induced bleaching
