Robinetin is an organic compound which belongs to flavones and has the molecular formula C₁₅H₁₀O₇.

Chemically, robinetin is a pentahydroxyflavone that is a flavone substituted by hydroxy groups at positions 3, 7, 3, 4' and 5'. Its name originates from the botanical name of the genus, Robinia sp.

Natural role

It has a role as a plant metabolite and is a pentahydroxyflavone and a 7-hydroxyflavonol.^[1] Robinetin is one of the basic chemical extracts of the species black locust, Robinia pseudoacacia and its wood, imparting a high biological resistance against several pathogens (fungi, insects).^[2]

As flavonoid, robinetin has also been isolated from the heartwood of the African species, Millettia stuhlmannii.^[3]

In plant systems, robinetin as flavonoids in general, help in combating oxidative stress and act as growth regulators.

Research

Recent research has focused on the health aspects of flavonoids for humans, particularly that of robinetin. It has been shown to possess a certain antioxidative activity, free radical scavenging capacity, coronary heart disease prevention, hepatoprotective, anti-inflammatory, and anticancer activities.^[4]

Robinetin also can inhibit lipid peroxidation and protein glycosylation.
