    摘要:

    采用大孔吸附树脂纯化樟树叶醇提液中木脂素类化合物。通过对比6 种大孔树脂对樟树叶中木脂素吸附-解吸效果,从中筛选一种最适大孔吸附树脂作为纯化材料,并研究上样浓度、上样流速、上样体积对大孔树脂吸附率的影响,以及洗脱剂浓度、洗脱流速、洗脱剂用量对大孔树脂解吸率的影响,通过正交试验优化大孔树脂纯化木脂素的工艺。试验结果表明,大孔树脂最佳吸附-解吸工艺条件为:7 BV 上样量、2.12 mg/mL 上样浓度、1.0 mL/min 上样速率、80% 乙醇洗脱剂、洗脱流速2 BV/h,洗脱剂用量8 BV,该条件下樟树叶中木脂素得率为66.68%,纯度为15.91%,表明该大孔树脂对于樟树叶中木脂素纯化效果较好。

    Abstract:

    In this study, six different macroporous adsorption resins were evaluated for their use to purify lignans ethanol-extraction of camphor tree leaves,a suitable macroporous adsorption resin was selected as the purification material. The effects were investigated, such as sample concentration, flow rate, volume of sample on adsorption rate of macroporous resin, and the effects of concentration, flow rate and dosage of eluent on desorption rate of the macroporous resin were also studied . The optimal purification process of lignan with the macroporous resin was studied by the orthogonal experiment. The purication parameters optimized by adsorption and desorption were determined as follows: sample loading amount 7 BV, sample concentration 2.12 mg/mL, ow rate 1.0 mL/min, dosage of desorption ethanol solvent 80%, ow rate 2 BV/h, eluent volume 8 BV. Under the optimized conditions, the yield and purify of lignans were 66.68% and 15.91%, respectively, which indicated that the macroporous resin has better purification effect on lignans in camphor leaves.
