摘　　要：目的:测定枸杞中铜、锌、锰、锂、钾、钠、钙、镁、锶、铁的含量。方法:原子吸收分光光度法。结果:铜含量10.643μg/g、钾131.186m g/g、钠12.037m g/g、钙1.295m g/g、镁3.346m g/g、锌58.056μg/g、铁59.321μg/g、锰13.563μg/g、锶32.013ug/g、锂0.458μg/g。结论:枸杞中钾、镁、铁、锌、锶含量丰富,铜、锰等微量元素含量也较多,这可能是枸杞具有补肾、润肺、生精、益气作用的重要因素之一。Objective ：To determine the contents of trace elements （Cu, Zn, Mn, Ge, Li, K, Na, Ca, Mg, Sr,Fe） in Frutus Lycii. Methods：Atomic absorption spectrophotometry was used to determine the contents. Result：The contents of trace elements were as follows： Cu 10. 643big/g, K 131. 186mg/g, Na 12. 037mg/g, Ca 1. 295mg/g, Mg 3. 346mg/g, Zn 58. 056μg/g, Fe 59. 32μg/g, Mn 13. 563μg/g, Sr 32. 013μg/g and Li 0. 458μg/g. Conclusion： K,M,Fe,Zn and Sr are rich in Frutus Lycii, and Frutus Lycii also has adequate Cu and Mn. Therefore, Frutus Lycii has the functions of nourishing the kidney and benefiting the lung.
