FIELD: chemistry.SUBSTANCE: present invention relates to a method of purifying Rebaudioside D and compositions based thereon. Proposed method comprises providing extract of Stevia rebaudiana Bertoni dissolving said extract in first aqueous solution of an organic solvent to obtain a first mixture of steviol glycosides, where said organic solvent is selected from a group consisting of methanol, ethanol and mixture of said substances, and concentration of said organic solvent is 75-99 vol% induction crystallisation in first mixture filtering said mixture to produce first precipitate and first filtrate dissolution of first precipitate in second aqueous solution of an organic solvent to obtain a second mixture, where said organic solvent selected from a group consisting of methanol, ethanol and mixture of said substances, and concentration of said organic solvent is 70-80 vol% induction crystallisation in second mixture filtering of said mixture to produce second precipitate and second filtrate dissolution of second precipitate in third aqueous solution of an organic solvent to produce a third of mixture, where said organic solvent is selected from a group consisting of methanol, ethanol and mixture of said substances, and concentration of said organic solvent is 10-80 vol% induction crystallisation in third mixture and filtration of said mixture to produce third precipitate and third filtrate to obtain purified Rebaudioside D. Proposed sweetener composition contains Rebaudioside D 81.6-95.7 wt%, Rebaudioside A 3.8-16.2 wt%, Stevioside 0.1-0.8 wt%, Rebaudioside C 0.1-0.7 wt%, Rebaudioside E 0.2-0.5 wt%, Rebaudioside F 0.1-0.2 wt%.EFFECT: novel efficient method of producing Rebaudioside D and effective sweetener composition based thereon.19 cl, 6 dwg, 12 tbl, 13 exНастоящее изобретение относится к способу очистки Ребаудиозида D и композиции на его основе. Предложенный способ включает обеспечение экстракта растения Stevia rebaudiana Bertoni растворение указанного экстракта
