【摘要】 目的建立益智仁最优煎药方法。方法采用浸泡煎煮、浸泡后下、直接后下三种煎煮方法提取中药挥发油,并采用气相色谱一质谱法(GC-MS)对三种方法提取的挥发油进行分析鉴定,以峰面积归一化法测定了各组分的相对百分含量。结果以浸泡后下5～10 min为最佳提取方法提取挥发油,通过GC-MS分析,浸泡后下所得的甘松挥发油共分离出34个峰,鉴定出24种成分,占挥发油总相对含量的89.95%。更多还原

【Abstract】 Objective To establish the best method for decocting Fructus Alpinlae Oxyphyliae.Methods Volatile oil was extracted with 3 different methods,i.e.decocting directly after soaking in water,decocting later after soaking in water and decocting later without soaking.The extracted oils were analyses and determined with GC-MS.Relative percentage composition of each components were determined with area normalization method.Results The best way to extract volatile oil was decocting 5~10min later after soaking in water.By GC-MS analysis,34 peaks were separated in rhizoma nardostachyos volatile oil extracted by decocting later after soaking,and 24 components were determined,which accounted for 89.95% of the total relative percentage composition.更多还原
