冬虫夏草与人工虫草菌丝体无机元素含量的比较

[目的 ]分析比较冬虫夏草及人工虫草菌丝体无机元素含量。 [方法 ]PS 6电感耦合等离子体发射光谱仪测定无机元素含量。 [结果 ]冬虫夏草、蝙蝠蛾拟青霉、虫草头孢菌、蝙蝠蛾被孢霉 4种样品中共测得 2 8种无机元素。 4种样品中P、K、Mg、Fe、Ca的含量均较高 ( >180mg/kg) ;As、Cd、Sb、Hg的含量均较低 ( <1.9mg/kg) ,且在蝙蝠蛾拟青霉和虫草头孢菌中未检出Hg元素。 [结论 ]冬虫夏草与人工虫草菌丝体在无机元素的组分和含量分布的高低趋势上基本一致

A Comparative Study of Inorganic Elements between Cordyceps Sinensis and Mycelium of Cultured Cordyceps Sinensis

Objective To detect and compare the contents of minerals in Cordyceps sinensis,Paecilomyces sinensis,Cephalosporium sinensis and Mortierella sinensis.[Methods] The contents of minerals were determined by PS-6 Inductively Coupled Plasma Emission Spectrometer.[Results] 28 kinds of minerals in Cordyceps sinensis,Paecilomyces sinensis,Cephalosporium sinensis and Mortierella sinensis were detedmined.The contents of P,K,Mg,Fe,Ca were all higher and more than 180 mg/kg.The contents of As,Cd,Sb,Hg were all lower and less than 1.9 mg/kg.Mercury(Hg) was not detected in Paecilomyces sinensis and Cephalosporium sinensis. [Conclusion] The mineral contents and their distribution in Cordyceps sinensis and mycelium of cultured Cordyceps sinensis were similar.
