俄罗斯桦褐孔菌中无机元素含量分析

采用原子荧光光谱法、石墨炉原子吸收光谱法和电感耦合等离子体光谱法,对俄罗斯桦褐孔菌原料及其制品中的铅、镉、汞、砷4种重金属元素和铝、硼、钡、钙、锡、钴、铜、铁、钾、镁、锰、钠、镍、磷、锶、钛、钒、锌18种微量元素含量进行了测定并分析了其差异性。结果表明:桦褐孔菌原料中22种无机元素含量较桦褐孔菌制品要高;深色桦褐孔菌原料中铝、钡、锡、铁、镁、钛、钒7种微量元素含量更高一些;桦褐孔菌原料内部铝、钙、铜、铁、钠、磷6种元素的含量比外皮更高。俄罗斯桦褐孔菌原料及其制品中的重金属含量符合中国的国家标准,不同原料其特征微量元素含量各不相同。

Analysis of inorganic elements in Russian Inonotus obliquus

To provide a basis of quality control and safety evalua-tion for developing medicine and functional food of Inonotus obliquus, 4 kinds of heavy metals including lead, cadmium, mercury, arsenic and 18 kinds of microelements including aluminum, boron, barium, calcium, tin, cobalt, copper, iron, potassium, magnesium, manganese, sodium, nickel, phosphorus, strontium, titanium, vanadium, zinc in different color, different part, and different products were detected by national standard, and relative statistical analyses were also carried out. Results showed that the contents of 22 inorganic elements in crude I. obliquus products were higher than that in refined I. obliquus products, while the contents of micronutrient in dark I. obliquus were higher than the light one especially in aluminum, barium, tin, iron, magnesium, titanium, and vanadium. The contents of micronutrient in inside of I. obliquus were higher than that in coat especially in aluminum, calcium, copper, iron, sodium, and phosphorus. The contents of heavy metals in raw materials and deep processing products of I. obliquus from Russia origin were within the scope of the national standards. The microelement was different depending on different materials. It ensures the efficiency for development of I. obliquus.
