采用HNO3/H2O2湿法微波消解制样,利用全谱直读电感耦合等离子体原子发射光谱法(ICP-OES),全面详细地分析测定了蕨麻中的矿质元素。共检出17种,分析结果相对标准偏差(RSD,n=9)在0.33%～10.8%之间,其中15种元素在5%以内;加标回收率在92.7%～108.5%之间,其中11种元素在(100±5)%范围内。蕨麻中所含的P、K、S、Mg、Ca、Na等人体常量元素的质量分数分别为0.94%、0.86%、0.45%、0.20%、0.14%和0.006%;人体必需微量元素Fe、Zn、Cu、Cr等的含量分别为25.8、1.84、0.32、0.086mg/100g;人体可能必需元素Si、Mn、B的含量分别为87.9、1.27、1.15mg/100g;此外还含有36.7mg/100g的Al以及微量的Sr、Ti、Ba等元素。
HNO3 / H2O2 wet microwave digestion was used for the determination of mineral elements in the fern. The ICP-OES was used to determine the mineral elements in the fern. A total of 17 species were detected. The relative standard deviations (RSDs, n = 9) were between 0.33% and 10.8%, of which 15 were within 5%. The spiked recoveries ranged from 92.7% to 108.5% Eleven elements are in the range of (100 ± 5)%. The mass fraction of P, K, S, Mg, Ca, Na and other human body elements contained in fern is 0.94%, 0.86%, 0.45%, 0.20%, 0.14% and 0.006%, respectively; Zn, Cu, Cr, etc. were 25.8,1.84,0.32,0.086mg / 100g; the human body may need elements Si, Mn, B content were 87.9,1.27,1.15 mg / 100g; also contains 36.7mg / 100g Of Al and a trace of Sr, Ti, Ba and other elements.
