摘　　要：目的:建立益智营养元素的测定方法,并对20个不同产地益智果实中营养元素镁、锌、锰、钙和铁的含量进行初步的比较研究。方法:采用原子吸收光谱法测定不同产地益智果实中营养元素镁、锌、锰、钙和铁的含量。结果:不同产地益智样品中含有丰富的Mg、Zn、Mn、Ca和Fe等元素,不同产地益智中营养元素存在差异性,最佳的益智产地为海南琼中长兴村、海南屯昌新兴镇和广西南宁。结论:测定方法快速、准确;测定结果将为益智的种植、质量评价以及资源的合理利用提供参考。Objective：To establish a method for determination of nutrient elements in Alpinia oxyphylla collected from different cultivation regions of China. Methods： The content of Mg, Zn, Mn, Ca and Fe was determined by atomic absorption spectroscopy. Results： The content of nutrient elements was high in A. oxyphylla. It was changed in the samples collected from different cultivation regions. The best cultivation regions of A. oxyphylla were from Changxing town of Qiongzhong county, Xinxing town of Tunchang county in Hainan province and from Nanning city in Guangxi province. Conclusion： The method was fast, accurate for determination of nutrient elements in A. oxyphylla. The results would provide valuable data for further investigation of A. oxyphylla.
