The invention relates to the preparation of phenolics derivatives by enzymatic condensation of phenolics selected among pyrocatechol or its derivatives with the glucose moiety of sucrose. The production of said phenolics derivatives is achieved with a glucosyltransferase (EC 2.4.1.5). These O-α-glucosides of selected phenolics are new, have a solubility in water higher than that of their parent polyphenol and have useful applications in cosmetic and pharmaceutical compositions, such as antioxidative, antiviral, antibacterial, immune-stimulating, antiallergic, antihypertensive, antiischemic, antiarrhythmic, antithrombotic, hypocholesterolemic, antilipoperoxidant, hepatoprotective, anti-inflammatory, anticarcinogenic antimutagenic, antineoplastic, anti-thrombotic, and vasodilatory formulations, or in any other field of application.
