摘 要：
采用70%甲醇溶液超声提取、HPLC-UV法测定细辛中的马兜铃酸Ⅰ的含量,检出限为0.20 ng,回收率为98.5%~103.5%.检测方法简单,分离度好,灵敏度高,稳定性好.细辛根、茎中未检出马兜铃酸Ⅰ,叶中含量为0.031 3~0.087 3 mg/kg,远低于药典限量要求0.001%,风险很低.

摘 要：
The content of aristolochic acid Ⅰ in asarum was determined by ultrasonic extraction with 70%methanol solution and HPLC-UV method.The detection limit was 0.20 ng.The recovery rate was 98.5%-103.5%.The detec-tion method is simple,with good separation,high sensitivity,and good stability.Aristolochic acid Ⅰ was not detected in the roots and stems of asarum,and the content in the leaves was 0.031 3-0.087 3 mg/kg,which was far below the pharmacopoeia limit of 0.001%,and the risk was very low.
