[Study on the determination of calcium in Chinese medicine by ICP-AES].
Calcium 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.
