摘    要:目的研究我国保健食品中使用频次较高的植物原料中植物甾醇含量,为今后植物原料的合理开发应用提供依据。方法在对我国目前保健食品原料使用频次分析的基础上,选择在保健食品中使用频次较高的药食两用植物30种、可用于保健食品的中药40种,按照本实验室建立的方法,用气相色谱法分析了这些植物原料中β-谷甾醇、菜油甾醇、豆甾醇、谷甾烷醇的含量,并计算总含量及各成分占总量的百分比。结果不同植物原料在保健食品中的使用频次不同,使用频次较多的如山楂为408次、黄芪为342次;所有被分析的样品中均检测到了植物甾醇,但不同植物原料中植物甾醇的含量差异很大,从总含量不足10mg/100g到高达380mg/100g,在各种"仁"、"子"的样品中植物甾醇的含量较高。大部分样品中含量最多的是β-谷甾醇。结论研究传统植物原料的功能成分,对合理开发中医药有重要意义;在某些中草药中,植物甾醇可能是其发挥作用的重要有效成分之一。

关 键 词:保健食品  植物原料  植物甾醇  含量研究

Abstract:Objective To analyze the phytosterol content in plant materials commonly used in functional food in China.Method Thirty kinds of food commonly used as medicines and forty kinds of Chinese herbs were chosen as samples.The contents of phytosterols(β-sitosterol,campesterol,stigmasterol,β-sitostanol) were analyzed by GC methods established by our laboratory.Results The frequency of various plant materials used in functional food was different,e-g.hawthorn about 408 times and huangqi 342 times.Phytosterols were contained in all samples analyzed,but were different in contents,some less than 10mg/100g while some more than 380mg/100g.In most samples,β-sitosterol is the largest portion of total phytosterol.Conclusion The phytosterols are important functional ingredients in plant materials frequently used in Chinese traditional medicine.The data of phytosterol contents in plant materials are valuable for utilization and further study in functional food.
Keywords:functional food  plant materials  phytosterol  content analysis
