| Abstract: | Fatty acids in the Malania oleifera oil of Yunnan were esterified by sulfuric acid methanol and analyzed by GC MS. Seventeen components were separated and seven acids as methylesters were identified and determined. They were hexadecanoic acid(1.50%),9c octadecenoic acid(21.54%),11c eicosenoic acid ( 7.04 %),13c docosenoic acid (18.29%),docosanoic acid (1.33%),15c tetracosenoic acid (40.92%),tetracosanoic acid (2.14%).There were 7.24 % components unidentified. |
