采用电感耦合等离子体原子发射光谱法(ICP-AES)对采自云南省的10种野生食用菌(灰牛肝菌(Boletus griseus)、美丽牛肝菌(Boletus speciosus)、拟潮乳菇(Lactarius hygrophoroides)、白霜菇(Leucopaxillus acuteus)、白盖菇(Macrocybe acutea)、黑菇(Melanoleuca acutata)、美味羊肚菌(Morchella deliciosa)、红柄小菇(Mycena haematopus)、雷氏粉牛肝菌(Pulveroboletus ravenelii)和松茸(Tricholoma matutake))中钙、铬、钴、铜、铁、镁、锰、钾、钠和锌等10种矿物元素的含量进行了分析。蘑菇的最低和最高元素含量测定为毫克每公斤干重的钙(38-470),铬(0.45-6.3)、Co(0.29-2.3)、Cu(13-58)、Fe(22-510)、Mg(84-550)、Mn(1.4 ~ 70)、K(1,300-4,600)、Na(190-670)、Zn(16-160)。蘑菇中矿质元素含量最高的是B. griseus对K和Na的影响; deliciosaforMn,L. Cr和Fe的含量,M. Ca、Mg、Zn含量显著高于T.这些结果表明,蘑菇中的矿物元素含量有很大的物种依赖性和环境因素的影响。
Ten species of wild edible mushrooms (Boletus griseus,Boletus speciosus,Lactarius hygrophoroides,Leucopaxillus giganteus,Macrocybe gigantea,Melanoleuca arcuata,Morchella deliciosa,Mycena haematopus,Pulveroboletus ravenelii, andTricholoma matsutake) collected from Yunnan province of China, were analyzed for ten mineral elements (calcium, chromium, cobalt, copper, iron, magnesium, manganese, potassium, sodium, and zinc) contents using ICP-AES. The minimum and maximum element contents of mushrooms were determined as milligrams per kilograms dry weight for Ca (38–470), Cr (0.45–6.3), Co (0.29–2.3), Cu (13–58), Fe (22–510), Mg (84–550), Mn (1.4–70), K (1,300–4,600), Na (190–670), and Zn (16–160). The mushrooms species with the highest levels of mineral elements wereB. griseusfor K and Na,P. raveneliifor Cu,M. deliciosafor Mn,L. giganteusfor Cr and Fe,M. giganteafor Ca, Mg and Zn,T. matsutakefor Co. These results demonstrate that the mineral element contents in mushrooms are considerably species dependent and affected by environmental factors.
