摘　　要：钙 (Ca)是人体中必需的元素 ,其含量直接影响到神经 ,肌肉的兴奋性 ;在神经 ,肌肉应激 ,神经冲动的传递 ,心动节律的维持 ,血液凝固 ,细胞粘着等生理过程中 ,具有重要的意义。为了探讨中药方剂中Ca的测定方法 ,文章采用湿法HNO3 HClO4消解对试样进行消解 ,用电感耦合等离子体原子发射光谱 (ICP AES)法测定酸枣仁汤的中药方剂、葛根中钙元素的含量 ,回收率分别为 97 7%和 10 4 4 % ,相对标准偏差为 1 7%。发现中药中含有丰富的钙元素 ,钙在中药中可能起到一定的药理作用 ,用ICPCalcium is the necessity element in human, body and its content has effect on exciting muscle or nerve. Calcium is important in the physiologic process of muscle or nervous reaction, nervous impulse transmission, heartbeat rhythm maintenance, blood solidification, cell coherence and so on. Determination of calcium element in Chinese medicine wild jujube seed decoction and radix puerariae was studied by ICP-AES after they were digested with HNO3 - HClO4. The precision (RSD) is 1.7%. The average recovery of calcium in wild jujube seed decoction is 97.7% and in radix puerariae is 104.4%. Calcium was abundant in Chinese medicine and could play-certain pharmacologic role in Chinese medicine. It is of important significance to assess the value of Chinese medicine by determination of calcium element in Chinese medicine with ICP-AES.
