摘要(Abstract)：
采用气相色谱-质谱联用技术对动态吸附法收集的贯叶马兜铃(Aristolochia delavayi Franch.)干燥叶和根的挥发性成分进行了分析,并用气相色谱面积归一化法对各成分进行了定量。从贯叶马兜铃叶中分离出19个挥发性成分,占挥发性成分总量的97.8%,其中反式-2-葵烯醛(79.79%)、3-十二烯醛(4.26%)、辛醛(2.49%)、反式-2-己烯醛(2.09%)和葵醛(1.80%)为主要成分。从该植物根中分离出16个挥发性成分,占挥发性成分总量的98.2%。其中乙酸龙脑酯(37.08%)、尼泊金丙酯(22.29%)、1,3,8-p-孟三烯(19.93%)、莰烯(6.39%)和β-蒎烯(2.21%)为主要成分。该研究结合当地居民的食用习惯,具体阐明了自然条件下贯叶马兜铃的叶及根的辛香味成分及组成,同时结合该植物不同部分的马兜铃酸的含量,讨论了食用该植物可能存在的健康安全风险。该研究结果能为今后科学食用及保护该濒危物种提供技术指导和理论支持。
