泸州桂圆果肉中微量元素含量分析
目的 确定泸州产桂圆肉中微量元素的含量。方法 采用微波消解, 电感耦合等离子体光谱质谱联用仪和电感耦合等离子体光谱仪对桂圆肉中16种微量元素进行检测。结果 泸州本地产桂圆肉中钾平均含量高达20 g/kg; 其次是钙和镁, 平均约为600 mg/kg; 钠的平均含量约40 mg/kg; 铁、硼、铜、锌、含量均大于10 mg/kg、锰的含量约为5 mg/kg。同时含有微量的镍、钼、钴、硒、铬、锡; 在方法检出限范围内, 未检测到钒。结论 泸州桂圆中含有人体必需的微量元素, 同时含有丰富的钾、钙、镁。
Objective To determine the content of trace elements in longan pulp of Luzhou. Methods Sixteen kinds of trace elements were detected by microwave digestion and inductively coupled plasma spectrometry-mass spectrometer and inductively coupled plasma spectrometer. Results The average potassium content in Luzhou longan pulp was as high as 20 g/kg and calcium and magnesium followed, with an average of about 600 mg/kg. The average sodium content was about 40 mg/kg, the iron, boron, copper, zinc content was more than 10 mg/kg, and manganese content was about 5 mg/kg. There were also containing trace amounts of nickel, molybdenum, cobalt, selenium, chromium, tin. Vanadium was not detected within the limit of detection of the method. Conclusion Luzhou longan contains essential trace elements in the human body and is rich in potassium, calcium and magnesium.
