摘　　要：目的对中国常见的50种药食两用植物和中草药中的植物甾醇的量和分布进行分析。方法选择了目前保健食品原料中常用的药食两用植物18种和中草药32种,用气相色谱法分析了β-谷甾醇、菜油甾醇、豆甾醇、谷甾烷醇的含量,并计算各成分占总量的百分比。结果18种药食两用植物中,植物甾醇的总含量从14.8mg/100g(生姜)到208.3mg/100g(火麻仁),而测定的32种中草药中,植物甾醇总含量则从9.4mg/100g(川贝母)到280.3mg/100g(柏子仁),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;传统用来降血脂、利尿、抗炎的中草药中含有较高的植物甾醇。结论50种保健食品常用原料中均含有一定量的植物甾醇。Objective To analyze the phytosterol content in food plant materials and Chinese traditional herbal medicines commonly used in China. Methods 18 kinds of food plant materials and 32 kinds of Chinese traditional herbal medicines, which were commonly used in functional food, were chosen as samples. The contents of β-sitosterol, campesterol, stigmasterol, β-sitostanol were analyzed by GC methods and the percent of each ingredient were calculated. Results The contents of phytosterols in 18 kinds of food plant materials were from 14.8mg/100g to 208.3mg/100g, while the content of phytosterols in 32 Chinese traditional herbal medicines were from 9.4mg/100g to 280.3mg/100g. In most samples, ^-sitosterol is the largest part of total phytosterol. Conclusion Phytosterols were existed in 50 kinds of food plant materials and Chinese traditional herbal medicines commonly used in functional food, maybe phytosterol is an important functional ingredient in some plant materials.
