摘要: 为优化超声波辅助羟丙基-β-环糊精(HP-β-CD)包埋椒目α-亚麻酸工艺,考察超声功率、超声时间、无水乙醇+混合脂肪酸:HP-β-CD质量比对包合率的影响。结果表明,最优工艺条件为超声功率300W、超声时间20min、无水乙醇+混合脂肪酸:HP-β-CD质量比1:8,此条件下包合率达90.26%,可实现α-亚麻酸的安全无毒分离。

Abstract: In order to optimize the ultrasonic-assisted hydroxypropyl-β-cyclodextrin (HP-β-CD) embedding of α-linolenic acid from Zanthoxylum bungeanum Maxim seeds, the effects of ultrasonic power, ultrasonic treatment time and mass ratio between absolute ethanol plus mixed FFAs and HP-β-CD on embedding efficiency were explored. The results indicated that the optimal embedding conditions were ultrasonic power of 300 W, ultrasonic treatment time of 20 min and (ethanol + FFAs)-to-HP-β-CD mass ratio of 1:8. Under these conditions, the embedding rate of α-linolenic acid reached up to 90.25%, which allowed the safe and non-toxic separation of α-linolenic acid.

Key words: hydroxypropyl-β-cyclodextrin, Zanthoxylum bungeanum Maxim seeds, α-linolenic acid, ultrasonic, high performance liquid chromatography
