Abstract:

With the steam distillation method, the volatile oils in leaves of Sabina przewalskii in Qilian county and Huzhu county were extracted and then their chemical constituents were analyzed by techniques of GC-MS-computer. The results showed that the major components were sesquiterpenoid and terpenol of the volatile oils. The average oil yield of the volatile oils from leaves of Sabina przewalskii in Qilian county and Huzhu county was 1.182% and 1.175%(w/w), respectively. 33 and 30 compounds were identified from the above two volatile oils, respectively. The identified relative contents of volatile oils were 94.51% and 92.59%, respectively. The main constituents of the former were α-pinene (25.83%), d-limonene (14.64%), β-phellandrene (8.98%), thujopsene (7.93%), (+)-a-muurolene (3.60%); but the main constituents in the latter were 4-methylene-1-(1-methylethyl)-bicyclo[3.1.0]hexane(14.35%),α-pinene(11.71%), d-limonene(8.62%), cedrol(7.46%), [s-(E,E)]-1-methyl-5-methylene-8-(1-methylethyl)-1,6-cyclodecadiene(7.40%), 4-methyl-1-(1-methyleth-yl)-3-cyclohexen-1-ol(5.46%), [1R-(1.alpha.,3.alpha.,4.beta.)]-4-ethenyl-.alpha.,alpha.,4-trimethyl-3-(1-methylethenyl)-cyclohex-anemethanol (4.65%), (1S-cis)-1,2,3,5,6,8a-hexahydro-4,7-dimethyl-1-(1-methylethyl)-naphthalene(4.59%), 1-methyl-4-(1-methy-lethyl)-1,4-cyclohexadiene(3.52%),caryophyllene(3.37%).The differences of compounds and GC contents between the two volatile oils extracted from leaves of Sabina przewalskii in Qilian county and Huzhu county were all distinct, but main compositions were all terpene compounds, which contains a lot of bioactive compounds with very important uses for perfume and medicine industry.
