| 摘 要： | 利用索氏提取法提取樟芝(Antrodia camphotrata)液体发酵菌丝中的脂肪酸,并利用气相色谱和质谱联用法(GC-MS)分析提取物中脂肪酸的种类与含量.结果显示,樟芝液体发酵菌丝中含有9种脂肪酸,分别为十四碳酸(14∶0)2.80%、十五碳酸(15∶0)5.01%、棕榈酸(16∶0)17.41%、硬脂酸(18∶0)7.62%、油酸(18∶1)30.18%、亚油酸(18∶2)19.74%、α-亚麻酸(18∶3)0.96%、γ-亚麻酸(18∶3)15.95%和二十碳四烯酸(20∶4)0.33%;其中饱和脂肪酸相对含量较少,为32.84%,不饱和脂肪酸相对含量较多,为67.16%;在不饱和脂肪酸中,必需脂肪酸占55.06%.-

| Abstract: | Gas Chromatography-Mass Spectrometry (GC-MS) identified nine fatty acids, C14H28O2 (2.80%), C15H30O2 (5.01%), C16H32O2 (17.41%), C18H36O2 (7.62%), C18H34O2 (30.18%), C18H32O2 (19.74%), C18H30O2 (α-Linolenic acid,0.96%), C18H30O2 (γ-Linolenic acid,15.95%) and C20H32O2 (0.33%) in Soxhlet extracts of Taiwanofungus formosanus mycelium grown in submerged culture. The saturated and unsaturated fatty acids contents were 32.84% and 67.16% respectively, and the percentage of essential fatty acids in the unsaturated fatty acid fraction was 55.06%.- |
