La présente invention est relative à un procédé de fabrication de dérivés de flavonoïde O-α-glucosylé comprenant au moins une étape d'incubation d'au moins un glucane-saccharase avec un flavonoïde et au moins un saccharose, le flavonoïde étant de formule (I) : Elle concerne également de nouveaux dérivés de flavonoïde O-α-glucosylés ainsi que leur utilisation. The invention relates to a method for producing derivatives of O-α-glucosylated flavonoid, comprising at least one step of incubating a glucansucrase with a flavonoid and at least one sucrose, the flavonoid being a flavonoid which is monohydroxylated or hydroxylated in a non-vicinal manner on the B cycle. The invention also relates to novel O-α-glucosylated flavonoid derivatives, and to the use thereof.
