摘要
研究川贝母的挥发性化学成分。川贝母样品经水蒸气蒸馏得挥发油,并用气相色谱-质谱法进行分析,按峰面积归一化法求出挥发性化学成分的相对含量。分离出39个峰,已鉴定了14个化合物,占其挥发油总相对含量的81.92%。已鉴定的化合物主要包括1-十八烯(16.38%),1-十二烯(15.09%),十六烷基-环氧乙烷(11.38%),棕榈醇(10.65%),花生醇(7.95%),9-十八炔酸甲酯(6.94%),n-十六酸(5.41%)。
To determine the volatile condtituents in Fritillaria cirrhosa D.Don. The volatile oil was obtained by water steam distillation and was used for gas chromatography-mass spectrometry （GC-MS） determination.The relative content of each component was determined by area normalization.Results Thirty-nine peaks were separated,among which 14 compounds were identified, amounting to 81.92 % of the total amount of volatile oil. The main compounds identified were found to be 1-Octadecene （16.38 %）, 1-Dodecene（15.09 %）, Oxirane, hexadecyl-（11.38 %）,1-Hexadecanol （10.65 %）, 1-Eicosanol （7.95 %）, 9-Octadecynoic acid, methyl ester （6.94 %）, n-Hexadecanoic acid（5.41%）.
