摘　　要：以长势优的成年驱蚊草为研究材料,采用顶空套袋法收集挥发物,并在TDS条件下用气相色谱-质谱联用仪(GC-MS)对收集挥发物进行分析检测,测出叶片挥发物有58种。包括烷烃、烯烃等10类化合物,烯烃中的萜烯类化合物有32种(相对含量为61.35%),其中香茅醛含量最多(相对含量为14.46%);同时结合保留指数分析驱蚊草叶片挥发物化学成分,比单独使用GC-MS其结果更加准确、可靠,有助于驱蚊草的进一步开发利用。Under the condition of TDS,the volatile matter was extracted by dynamic headspace collection method with good adult Pelargonium graveolens,and the composition of the extract was detected by gas chrom atograph-mass spectrometer（GC-MS）.There were 58 kinds of volatile matter,including ten types of compounds,such as alkane,olefins etc.There were 32 types terpenoid（relative content of 61.35%）,and the content of citronellal was the highest in simple carbohydrate（relative content of 14.46%）.Then,our work demonstrated that retention index could provide a complementary and convenient method for accurate analysis of the volatile matter from leaves of P.graveolens.The results obtained may be helpful for the further exploitation of P.graveolens.
