摘　　要：为了探究百合科Liliaceae植物挥发物(VOCs)成分组成,采用活体植物动态顶空套袋采集法收集吊兰Chloro-phytum comosum,一叶兰Aspidistra elatior和文竹Asparagus plumosus 3种百合科植物VOCs,利用热脱附-气相色谱/质谱联用法分析了这3种植物VOCs的主要成分。结果表明:吊兰释放34种VOCs,包含萜类、酯类、醇类、醛类、酸类等5类化合物,其中二氢香茅醇相对含量最高(28.79%);一叶兰释放VOCs共鉴定出25种,包含醛类、酯类、醇类、萜类、酮类、烃类等6类化合物,其中壬醛(相对含量为12.12%)为其主要成分;文竹释放出38种VOCS,包含萜类醛类、酯类、醇类、醛类等4种化合物,主成分为牻牛儿醇(相对含量为27.90%)。3种百合科植物挥发物中都含有萜类化合物、醇类化合物、醛类化合物、酯类化合物。研究结果为百合科植物的综合开发利用提供了理论依据。To understand the constituents of volatile organic compounds（VOCs） in Liliaceae,VOCs from Chlorophytum comosum,Aspidistra elatior,and Asparagus plumosus were collected using the dynamic headspace air-circulation method.Then,the main VOCs compounds were identified with thermal desorption system-gas chromatography/ mass spectrum（TDS-GC/MS）.Results showed that C.comosum emitted 34 types of VOCs（mainly as terpenoids,esters,alcohols,aldehydes,and acids） with dihydro-citronellol the most abundant compound（28.79%）.Aspidistra elatior emitted 25 types of VOCs（mainly as aldehydes,esters,alcohols,terpenoids,ketones,and hydrocarbons） with Nonanal the most abundant compound（12.12%）.Asparagus plumosus emitted 38 types of VOCs（mainly as terpenoids,esters,alcohols,and aldehydes） with lemonol the most abundant compound（27.90%）.Thus,these three species,with alcohols,terpenoids,aldehydes,and esters all found in the VOCs,will provide a theoretical basis for multiple utilization and development of Liliaceae.[Ch,2 fig.1 tab.21 ref.]
