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 quantity and distribution of phytosterols in 50 common medicinal and dual-use plants and Chinese herbal medicines in China. Methods 18 kinds of medicinal and dual-purpose plants and 32 kinds of Chinese herbal medicines commonly used in the raw materials of health foods were selected. The contents of β-sitosterol, campesterol, stigmasterol and sitostanol were analyzed by gas chromatography, and the components were calculated. Percentage of total. Results The total content of phytosterols was 18.8 mg/100 g (ginger) to 208.3 mg/100 g (hemp seed) in 18 kinds of medicinal and dual-purpose plants, and the total content of phytosterols was 9.4 mg in 32 kinds of Chinese herbs. /100g (Fritillaria Fritillaria) to 280.3mg/100g (Boziren), the content of phytosterols is higher in various samples of “Ben” and “Zizi”. Most of the samples contained the most β-sitosterol; traditional Chinese herbs used to lower blood lipids, diuretic and anti-inflammatory contained higher phytosterols. Conclusion The 50 kinds of health food commonly used raw materials contain a certain amount of phytosterols.
