  The present invention provides a method for preparing a glycoside of a flavonoid compound, which comprises the step of treating flavonoid and a glycosyl donor with an enzymatic agent having glycosylation activity and being derived from the genus Trichoderma (preferably Trichoderma viride or Trichoderma reesei ). Such a flavonoid compound includes a catechin compound or a methylated derivative thereof, and the glycosyl donor includes a carbohydrate containing a maltotriose residue (preferably maltotriose, maltotetraose, maltopentaose, maltohexaose, maltoheptaose, dextrin, γ-cyclodextrin or soluble starch). Glycosides obtained by the present invention have higher water solubility, improved taste, and increased stability. The present invention also provides novel glycosides of catechin compounds, which are obtained by the method of the present invention.

  公开（公告）日：2007-12-19

  The invention relates to the preparation of phenolics derivatives by enzymatic condensation of phenolics selected among pyrocatechol or its derivatives including (i) protocatechuic acid and its derivatives, (ii) 3,4-dihydroxycinnamic acid with its transisomer or caffeic acid and its derivatives, especially hydrocaffeic acid, rosmarinic acid, chlorogenic acid and caffeic acid phenethyl ester, and with its cis-isomer and its derivatives, especially esculin, (iii) dihydroxyphenylglycol, and (iv) members of the flavonoid familly such as taxifolin and fustin (dihydroflavonols), fisetin (a flavonol), eriodictyol (a flavanone), , with the glucose moiety of sucrose. The production of said phenolics derivatives is achieved with a glucosyltransferase (EC 2.4.1.5) obtained from a culture of Leuconostoc species, and more particularly from the culture of Leuconostoc mesenteroides NRRL B-512F. These O-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, antiarrhytmic, antithrombotic, hypocholesterolemic, antilipoperoxidant, hepatoprotective, anti-inflammatory, anticarcinogenic antimutagenic, antineoplastic, anti-thrombotic, and vasodilatory formulations, or in any other field of application. All the more, glucosylated phenolics derivatives objects of the invention can be hydrolyzed by the human natural microbiotes, thus releasing the active part of the phenolic compound upon time during their usage or by an α-glucosidase (EC 3.2.1.20).
