摘　　要：延药睡莲(Nymphaea stellata)是分布于我国的5个睡莲原生种之一,目前有关海南野生延药睡莲的挥发性油研究未见报道。为深入了解野生延药睡莲花挥发性成分组成,本研究采用超临界二氧化碳萃取技术,结合气相色谱-质谱联用技术对其花的挥发性成分进行提取和分析。结果显示,海南野生延药睡莲花主要挥发性成分组成为:二十一烷(Heneicosane)、香叶基香叶醇(Geranylgeraniol)、二十四烷(Tetracosane)和二十八烷(Octacosane),约占总挥发油的50%,明显不同于人工栽培的延药睡莲的精油组成。本研究对海南原生延药睡莲的保护和开发具有重要参考价值。Nymphaea stellata is one of the five typical native species distributed in China.No research on volatile oil of wild N.stellata in Hainan Island was reported.Wild N.stellata was extracted by using supercritical CO_(2) fluid extraction and analyzed by using GC-MS techniques to identify its volatile constituents.The results showed that heneicosane,geranylgeraniol,tetracosane and octacosane are the main ingredients in the wild N.stellata,accounting for nearly 50%of the total volatile components,which are obviously different from those of the cultivated N.stellata.This result might provide reference for the conservation and development of the wild N.stellata native in Hainan.
