目的:研究鬼箭羽药材中挥发性化学成分。方法:采用水蒸气蒸馏法提取鬼箭羽挥发油性成分,经气相色谱-质谱联用仪(GC-MS)分析。结果:鉴定了其中的56个挥发性化合物,占总挥发油的82.64%以上。其挥发性组分主要是羧酸、醛、酮、萜类化合物及其含氧衍生物,该法获得的相对含量最高的是棕榈酸39.69%,其次是冬青油5.02%,其他含量较高的成分依次是:9,12-十八碳二烯酸5.14%,十四烷酸2.79%,正己醛2.71%,9,12,15-十八碳三烯酸2.59%,十五烷酸2.31%,壬醛1.60%,月桂酸1.34%,六氢金合欢基丙酮1.25%。结论:鬼箭羽挥发油中的许多化合物,具有多种生物学活性。
Objective: To study the volatile chemical components of ghost arrow feather medicinal materials. Methods: The volatile components of ghost feather feathers were extracted by steam distillation and analyzed by gas chromatography-mass spectrometry (GC-MS). Results: 56 volatile compounds were identified, accounting for more than 82.64% of the total volatile oil. The volatile components are mainly carboxylic acids, aldehydes, ketones, terpenoids and their oxygen-containing derivatives. The highest relative content of this method is palmitic acid 39.69%, followed by wintergreen oil 5.02%, the other content is higher The components were as follows: 5.14% of 9,12-octadecadienoic acid, 2.79% of tetradecanoic acid, 2.71% of n-hexanal, 2.59% of 9,12,15-octadecatrienoic acid and 2.31% , 1.60% nonanal, 1.34% lauric acid, and 1.25% hexahydropropyl acetone. Conclusion: Many compounds in the volatile oil of Ghost Arrowhead have a variety of biological activities.
