摘　　要：目的:鉴定由超临界CO2流体萃取的沙棘籽的化学成分。方法:利用超临界CO2萃取和气-质联用技术对沙棘籽的化学成分进行分析。结果:沙棘籽的超临界CO2萃取物,气相色谱-质谱联用可分离并鉴定出61种化合物,主要成分为烷烃类、烯烃类、氯代烃、脂肪酸、烯酸、酯类等。结论:沙棘籽中含有较多酯类化合物,但有营养价值的有机酸类化合物种类、含量较少。Objective： Identify compounds of seeds of Hippophae rhamnoides L. extracted by supercritical CO2. Methods： GC - MS was used to analyse seeds of Hippophae rhamnoides L. extracted by supercritical CO2. Results： 61 compounds were separated and identified. The seeds of Hippophae rhamnoides L. contain alkane ,olefins ,chlorinated paraffin, fatty acid, olefine acid and esters. Conclusion：There are many esters in seeds of Hippophae rhamnoides L. , but organic acid of nutritional value is rare.
