Thanks to several components with health-promoting properties, mushrooms are recognized as a practical functional food and a valuable source of nutrients for the food industry. Ergosterol, the major sterol in edible mushrooms and a precursor of vitamin D2 with proven pharmacological activity and nutritional value, has become a very important topic in chemical and medical research. The main objectives of this study were to determine the ergosterol content in different species of Serbian wild mushrooms and in commercial mushrooms from Korean and Serbian grocery stores using square-wave voltammetry, to compare the concentrations in different parts of white button mushrooms, and to determine a possible relationship between Zn, Cu and Fe and ergosterol contents. The ergosterol contents varied between 0.01 and 7.04 mg/g (dry mass) of the mushrooms and were generally higher in cultivated mushrooms than in wild mushrooms. In addition, the ergosterol concentration was higher in the stems than in the caps of the mushrooms examined. Iron, Zn and Cu contents varied between the mushroom species at 8.5-479.9, 13.1-149.7 and 1.62-93.03 mg/kg, respectively, and principal component analysis (PCA) extracted two factors explaining 79.14% of the total variance, suggesting a direct relationship between iron and ergosterol content. This is the first comprehensive study to analyze and evaluate ergosterol concentrations in edible mushrooms from Korea and Serbia.
由于含有多种具有促进健康特性的成分，蘑菇被公认为是一种实用的功能性食品，也是食品工业宝贵的营养来源。麦角甾醇是可食用蘑菇中的主要甾醇，也是具有已证实药理活性和营养价值的维生素D2的前体，已成为化学和医学研究中一个非常重要的课题。本研究的主要目的是使用方波伏安法测定塞尔维亚野生蘑菇不同品种以及韩国和塞尔维亚杂货店的市售蘑菇中的麦角甾醇含量，比较白蘑菇不同部位的浓度，并确定锌、铜、铁与麦角甾醇含量之间可能存在的关系。蘑菇中麦角甾醇含量在0.01至7.04毫克/克（干重）之间变化，一般栽培蘑菇中的含量高于野生蘑菇。此外，在所检测蘑菇的茎中麦角甾醇浓度高于菌盖。不同蘑菇品种中铁、锌和铜的含量分别在8.5 - 479.9、13.1 - 149.7和1.62 - 93.03毫克/千克之间变化，主成分分析（PCA）提取了两个解释总方差79.14%的因子，表明铁与麦角甾醇含量之间存在直接关系。这是第一项全面分析和评估韩国和塞尔维亚可食用蘑菇中麦角甾醇浓度的研究。
