采用微波消解法处理罗汉果样品,运用电感耦合等离子体质谱法(ICP-MS)测定罗汉果样品中的微量元素钠(Na)、镁(Mg)、钾(K)、钙(Ca)、锰(Mn)、锌(Zn)、砷(As)、硒(Se)、汞(Hg)和铅(Pb).在优化实验条件下,方法的检出限为0.19~20.3μg/g,精密度为2.92%~10.9%,回收率为80.83%~105.60%.

Siraitia grosvenorii samples can be treated by microwave digestion method,using inductively coupled plasma mass spectrometry( icp-ms) determination of trace elements in samples of fructus momordicae sodium( Na),magnesium( Mg),potassium( K),calcium( Ca),manganese( Mn),zinc( Zn),arsenic( As),selenium( Se),mercury( Hg) and lead( Pb). Under the optimized experimental conditions,the method of detection limit of 0.19 ~ 20.3 μg/g,relative standard deviation is 2.92% ~ 10.90%,recovery rate is 80.83% ~ 105.60%.
