本文通过水蒸气蒸馏、超临界CO2萃取和顶空萃取三种方法并结合GC和GC/MS技术分析藏药镰形棘豆(Oxytropis falcate Bunge)中的挥发性成分,共鉴定出58个化合物,分别占71.0%,85.6%和84.5%.烷烃类、黄酮类和醛类化合物为主要挥发性成分.3种方法得到的挥发性成分在保留时间值上具有一定的连续性,能更完全地阐述清楚藏药镰形棘豆的挥发性成分,为进一步开发利用这种药用植物提供科学依据.

To examine the volatile compositions from Oxytropis falcate Bunge,the volatiles were obtained using water distillation,supercritical CO2 and headspace extraction methods and their chemical compositions were analyzed by GC and GC/MS.58 compounds were identified and the amount of the identified compounds represented for 71.0%,85.6% and 84.5% of all the volatiles,respectively.The main components were paraffin hydrocarbons 30.1% (water distillation),flavonoid compounds 68.5% (supercritical CO2 extraction) and aldehyde compounds 53.8% (headspace extraction).In addition,micromolecular terpenoids,organic acids,esters,aldehydes and nitrogenous compounds were also identified.It suggested that retention times of the volatiles extracted using three methods were consecutive which could provide a comprehensive volatile composition of O.falcate Bunge and a scientific basis for further development and utilization of this medicinal plant.
