树莓干果粗黄酮纯化和活性研究

A study on the purification and ctivity of total flavonoids from raspberry dry fruits

  • 摘要: 以树莓干果为原料,通过比较HP-20、D101、X-5、LX-68、AB-8、XDA-6、XDA-8、D201大孔树脂对树莓粗黄酮静态吸附率和解吸率的影响,筛选出适宜分离纯化树莓黄酮的大孔树脂为XDA-6树脂.结合静态与动态吸附解吸实验,得出用XDA-6大孔树脂分离纯化树莓黄酮的最佳工艺.将树莓粗黄酮提取原液作为上样液,以6BV/h (1BV为1个柱体积)的流速上样吸附,之后采用60%乙醇作为洗脱剂,以4BV/h的流速进行洗脱,洗脱剂用量为5BV.在此纯化条件下所得树莓黄酮质量分数为35.8%,较纯化前提高了1.21倍;干粉质量浓度在0.5mg/mL时,对DPPH的抗氧化活性从纯化前的62.51%提高到70.36%,对大肠杆菌、金黄色葡萄球菌、棉花枯萎菌、小麦赤霉菌均有一定的抑制作用,纯化后的抑菌效果优于纯化前.

     

    Abstract: By comparing static-adsorption and desorption rate of HP-20,D101,X-5,LX-68,AB-8,XDA-6,XDA-8 and D201 macroporous resins,XDA-6 was considered to be the optimum resin to purify the crude flavonoids of raspberry dry fruits.By combining the static and dynamic experiments of resin adsorption-desorption,the optimum purification process was as follow:Taking crude flavonoids solution as sample,loading velocity at 6BV/h (1 column volume as 1BV),60 % alcohol as elution agent with 4BV/h elution velocity,and 5BV eluent volume.The purified flavonoids content by the process was 35.8 %,which was 1.21 times more than that of the unpurified flavonoids solution.When dry mass concentration was 0.5mg/mL,the antioxidant activity of total flavonoids to DPPH increased from 62.51 % to 70.36 % after purification.The antibacterial effect of purified total flavonoids on Escherichia coli,Staphylococcus aureus,Cotton fusarium Wilt vasinfectum and Fusarium graminearum was better than unpurified flavonoids.
