1、实用文档油莎豆全成分分析陈星1陈滴2刘蕾1(长春大学吉林省农产品加工生物技术重点实验室长春130022)1(吉林大学药学院长春130023)2摘要本文研究分析了油莎豆的基本成分和功能性有效成分。油莎豆基本成分蛋白质、脂肪、糖、淀粉、水分含量分别为8.00%、26.50%、23.35%、23.21、7.00%。通过对油莎豆有效成分的定性定量分析得知,油莎豆中含有有机酸、甾类化合物、萜类被检出,黄酮、蒽醌、酚类、香豆精、内酯、强心甙未检出,对油莎豆糖进行的薄层层析和高效液相分析结果表明:油莎豆糖分主要有蔗糖
2、、葡萄糖、果糖、棉子糖,未见有其他糖类。气相色谱仪分析油莎豆脂肪酸组成,结果表明油莎豆油脂中油酸是主要成分,占52.57%,其次是棕榈酸20.39%和油酸20.10%。油脂中维生素E含量为0.15%,甾醇含量为0.53%,说明说明油莎豆油脂是不干性油,油脂中营养成分较高。关键词:油莎豆全成分Cyperusesculentuswholecomponentanalysischenxing1chendi2liulei1(ChangchunUniversityinJilinProvincefocusonthep
