| 摘 要： | 确定了制备芝麻木脂素的最佳树脂为H1020型大孔吸附树脂,优化工艺条件为:室温,芝麻混合油中木脂素质量浓度1.54 mg/mL,吸附流速2.0 BV/h,解吸剂为体积分数为90％乙醇,解吸pH值4.2,解吸流速为1 BV/h.在此条件下,芝麻木脂素回收率大于65％,产品中木脂素总含量(以芝麻素计)达到85％.经液相色谱-质谱联用仪分析,制得木脂素的主要成分为芝麻素、芝麻林素和松醇素.

| Abstract: | The paper determined the H1020 macroporous adsorption resin as the optimal resin for preparing sesame lignans,and optimized the process conditions.The optimized preparation conditions of the sesame lignans were as follows: room temperature,mass concentration of lignans in the sesame oil mixture 1.54 mg/mL, adsorption flow rate 2.0 BV/h,90% ethanol as desorption agent,desorption pH 4.2,and desorption flow rate 1.0 BV/h.Under the optimal conditions,the yield of sesame lignans was larger than 65%,and the total... |
