对新疆野生麻黄属植物资源进行了调查。麻黄属植物主要生长在塔克拉玛干沙漠和古热班-通古特沙漠边缘。结果表明，新疆地区广泛分布着6种基因型的青海麻黄。中麻黄3个基因型仅分布于新疆北方和东部，而麻黄分布于新疆北方。对这些麻黄样品进行了核糖体DNA、内转录间隔区1和2、叶绿体DNA、trnL内含子和trnL-trnF基因间隔区的序列分析。E.普氏原羚分布于不同的生境。测定了样品中去甲麻黄碱、麻黄碱、伪麻黄碱和甲基麻黄碱的含量。三种基因型的中间麻黄均含有麻黄碱类生物碱，而E. regeliana和E.普氏原羚
The resources of wild Ephedra plants in the Xinjiang Uygur Autonomous Region were surveyed. Ephedra plants mainly grow on the fringes of the Taklimakan Desert and Gureban-tonggute Desert. We found six genotypes of Ephedra przewalskii growing widely in Xinjiang. Three genotypes of Ephedra intermedia were limited to the northern and eastern parts, and Ephedra regeliana scattered in the northern part of Xinjiang. These Ephedra specimens were analyzed for DNA sequences of nuclear ribosomal DNA, internal transcribed spacers 1 and 2, chloroplastic DNA, trnL intron and trnL-trnF intergenic spacer. Intraspecific variation of the nucleotide sequence in E. przewalskii was found in different habitats. Norephedrine, ephedrine, pseudoephedrine, and methylephedrine contents of the specimens were determined. Although Ephedra intermedia of all three genotypes contained ephedrine alkaloids, ephedrine alkaloids were not detected in E. regeliana and E. przewalskii.
