| 摘 要： | 采用混合溶剂热回流提取法和超声波辅助提取法,研究不同比例浓度的混合溶剂、超声波频率、萃取时间对甘蔗皮渣中蔗蜡脂产率的影响.结果显示,70%乙醇含量的乙醇-汽油混合溶剂可作为最适提取溶剂,在45 KHZ频率的超声波下萃取4 h,蔗蜡脂产率可达最高值7.0%,纯化蔗蜡产串可达4.6%;蔗蜡脂产物经皂化、柱层析纯化后,气相色谱-质谱(GC-MS)定性定量分析其纯度达70.45%,主要成分为C22～C30的偶碳脂肪醇类和植物甾醇衍生物,单组分成分最高为C28脂肪醇,含量为50.34%,植物甾醇主要是麦角甾醇和豆甾醇的衍生物,含量分别为4.72%和1.12%.试验研究为甘蔗高附加值产物蔗蜡脂的提取制备提供了一种新的方法. |
