    摘要:

    采用乙醇发酵去除酶法合成α-熊果苷反应液中大部分糖类杂质,以活性炭纤维吸附分离α-熊果苷,选择甲醇-乙酸乙酯混合溶剂重结晶精制。结果表明,50%乙醇溶液洗脱部分α-熊果苷含量最高,此部分经甲醇-乙酸乙酯混合溶剂反复重结晶精制,可制备得到α-熊果苷无色针状结晶,HPLC检测纯度达到99%以上,收率达到80%。该工艺简单可行,稳定性高、重复性好,适合大规模制备高纯度α-熊果苷。

    Abstract:

    The majority of carbohydrate impurities in the mixture of α-arbutin enzymatic synthesis reaction were removed with alcoholic fermentation.An activated carbon fiber column was used to enrich α-arbutin with water and different concentration ethanol elution.The final recrystallization with methanol-ethyl acetate mixed solvent was used to obtain α-arbutin crystal.The results showed that the 50% ethanol solution elution part had the highest concentration of α-arbutin.After concentrated by vacuum concentration,this part was recrystallized with methanol-ethyl acetate mixture.Some colorless,needle-like α-arbutin crystal was obtained.The purity of crystal was over 99% α-arbutin by HPLC analysis.The established method is useful for industry production with its simplicity,low cost and high purified product.It will provide reliable parameters for the massive industry production.
