摘要
目的对68种中草药植物甾醇的含量进行检测,为进一步认识和利用中草药中的有效成分提供依据。方法选择目前保健食品原料中批准可用的中草药68种,按照本实验室建立的方法,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。结果保健食品原料中可用的68种中草药中,植物甾醇的总含量从5.2mg/100g(诃子、鲜白茅根)到321.4mg/100g(蒲黄)。来源于植物的"花"、"种子"、"皮"等部位的样品中植物甾醇的含量较高。本次研究发现所有检测样品中都含有β-谷甾醇,且在绝大多数样品中此成分的含量最多;传统用来降血脂、抗炎的中草药中均含有较高的植物甾醇。结论 68种中草药中均含有一定量的植物甾醇,这可能是中药发挥作用的功能成分之一。
Objective To detect the content of phytosterols in 68 kinds of Chinese traditional herbal medicine and analyze the distribution of phytosterols in Chinese traditional herbal medicines. Method The content of β-sitosterol, campesterol,stigmasterol and β-sitostanol in 68 kinds of Chinese traditional herbal medicine commonly used in functional foods was analyzed by GC and the percentage of each ingredient was calculated. Results The contents of phytosterol in 68 kinds of Chinese traditional herbal medicine were from 5. 2 mg /100g to 321. 4 mg /100g. Total phytosterol was higher in seed,flower and bark. β-Sitosterol is the major part of total phytosterol in most samples. The Chinese traditional herbal medicines with higher phytosterols were used in health foods for anti-inflammation and lowering blood lipids.
