  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.

  该发明涉及通过酶催化将选择自间苯二酚或其衍生物的酚类与蔗糖的葡萄糖部分进行缩合来制备酚类衍生物。所述酚类衍生物的生产是通过葡萄糖转移酶（EC 2.4.1.5）实现的。所选酚类的这些O-α-葡糖苷是新的，其在水中的溶解度高于它们的原始多酚，并且在化妆品和药用组合物中具有有用的应用，如抗氧化、抗病毒、抗菌、免疫刺激、抗过敏、降压、抗缺血、抗心律失常、抗血栓形成、降胆固醇、抗脂质过氧化、肝脏保护、抗炎症、抗癌变突变、抗肿瘤、抗血栓形成和扩血管等配方，或者在任何其他应用领域中。

  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).

  本发明涉及用酶缩合法制备酚类衍生物，所选酚类包括焦儿茶酚或其衍生物，包括(i) 原儿茶酸及其衍生物，(ii) 3,4-二羟基肉桂酸与其反式异构体或咖啡酸及其衍生物，特别是氢咖啡酸、(iii) 二羟基苯甘醇，以及 (iv) 黄酮家族成员，如 taxifolin 和 fustin（二氢黄酮醇）、fisetin（一种黄酮醇）、eriodictyol（一种黄酮），以及蔗糖的葡萄糖分子。上述酚类衍生物的生产是通过一种葡糖基转移酶（EC 2.4.1.5）实现的，该酶是从白色念珠菌（Leuconostoc spECies）的培养物中获得的，尤其是从中肠白色念珠菌（Leuconostoc mesenteroides NRRL B-512F）的培养物中获得的。抗高血压、抗缺血、抗心律失常、抗血栓、降胆固醇、抗脂过氧化、保肝、抗炎、抗癌、抗突变、抗肿瘤、抗血栓和血管扩张配方，或任何其他应用领域。此外，本发明的葡糖基化酚类衍生物可被人体天然微生物水解，从而在使用过程中或通过α-葡萄糖苷酶（EC 3.2.1.20）释放出酚类化合物的活性部分。

  A process for producing an eriocitrin-containing material comprises the steps of: preparing an eriocitrin-containing citrus extract from a citrus fruit using an extractant; and separating eriocitrin from the citrus extract. The step of separating eriocitrin from the citrus extract comprises the steps of: bringing the citrus extract into contact with a porous synthetic adsorption resin such that eriocitrin in the citrus extract is adsorbed on the porous synthetic adsorption resin, the porous synthetic adsorption resin comprising a phenol-formaldehyde resin as a main framework and having amino and phenolic hydroxyl groups; and eluting the eriocitrin adsorbed on the porous synthetic adsorption resin using an elution solvent.
