摘要
从灵芝Ganodermalucidum孢子粉中检出18种常见氨基酸，总量为及7.29～7．71mg／100mg;其中甲硫氨酸含量高达330～3.48mg／100mg，人体必需氨基酸含量占总量的69.4～70．4％灵芝孢子粉含有棕榈酸（19．8％）、油酸（55.2％）、亚油酸（16.5％）以及少量的肉豆寇酸、硬脂酸、廿碳烯酸及廿二碳四烯酸等。对56种元素进行定量或半定量分析，结果表明灵芝孢子粉碳氮比C／N=17．57：1，含有磷1．28％、硫0.87％、硅0.92％、钾1.64mg／g、钠28μg／g、钙0．713mg／g、镁0.346mg／g、铁0．64mg／g、锌42.0μg／g、铜1.27μg／g、锰11μg／g、锶6．09μg／g等二十多种人体必需或有益的常量元素及微量元素。
Eighteen amino acids totalled 7.29 ~ 7.71mg /100mg were obtaned from the spores of log-cultivatated Ganoderma lucidum .Of which essential amino acids were 69.4% ~ 70.4% and methionine(Met) content was high espedally (up to 3.30 ~3.48mg /100mg) The fatty acids included teradecoic acid (C14:0, O.4%), palmitic and (C16: 0, 19.8%), stearic acid (C18:0, 0.3%), oleic acid (C18 : 1, 55.2%), linoleic acid (C18. 2, 16.5%), eicosenoic acid (C20:1, 1.3%), docotertraenic acid (C22: 4, 1.3%) and others. Elemen quantitative and semi-quantitative analysis showed that more than twenty kinds of macroelement and microelement were present, and C/N was 17.57: 1'.The contents of the elements were 1.28% for P, 0.87% S, 0.92% Si, 1.46mg /g K, 0.713mg /gCa, 0.346m /g Mg, 0.64mg /g Fe, 28μg /g Na, 42.0μg /g Zn, 12.7μg /g Cu,11μg /gMn, 6.09μg /g Sr.
