中文摘要: 神经酸是罗汉菜籽中含有的脂肪酸之一，研究表明神经酸对中枢系统疾病、脑血管疾病等的治疗有积极作用。为了富集罗汉菜籽中的神经酸，采用分子蒸馏结合尿素包合法，筛选分子蒸馏的最佳蒸馏温度：一级蒸馏温度140℃，二级蒸馏温度150℃。通过正交试验优化尿素包合法中的尿脂比、料液比、包合温度，得到最佳的工艺条件为尿脂比 1.25∶1，料液比 1∶12（g/mL），包合温度-10 ℃，最终神经酸含量可达到 26.23%。
Abstract:Nervonic acid is one of the fatty acids in Thlaspi arvense Linn seeds.Treatment with nervonic acid is beneficial for the central nervous system and cerebrovascular diseases.In this study，nervonic acid from T.arvense Linn seeds was purified using a combination of molecular distillation and urea inclusion.The optimal conditions of molecular distillation were a first level distillation temperature of 140℃and a second level distillation temperature of 150 ℃.An orthogonal experiment determined that the optimal urea inclusion conditions were，a urea to fatty acids ratio of 1.25∶1，material to liquid ratio of 1∶12（g/mL），and an inclusion temperature of-10 ℃.The yield of nervonic acid was 26.23% upon using the combination of molecular distillation and urea adduction technology.
