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.The paper determined the HI020 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 content of lignans in the product （calculated by sesamin） was up to 85%. The results of HPLC-MS analysis showed thatthe lignans mainly contained sesamin, sesamolin and pinoresinolin.
