Chemical components of essential oils from the herb of Sabina pingii var.wilsonii.

Aim ：To provide the foundation for reasonable utilization by analyzing the essential oils of Sabina pingii var.wilsonii.. Methods ：The essential oils were extracted using steam distillation and separated with GC capillary column.The components were quantitatively determined with normalization method，and were preliminarily identified by GC-MS. Results ：79 Components were identified，which took up 93.78% of the essential oils. Conclusion ：The main components of essential oils were α-terpineol(16.70%)；α-fenchene(14.98%)；2，6，10-dodecatrien-1-ol，3，7，11-trimethyl-(6.49%)；1，4-cyclohexadiene，1-methyl-4-［1-methylethyl］-(4.74%)；kaura-5，16-dien-18［or19］-ol(3.62%)；naphthalenemethanol，1，2，3，4，4a，5，6，7-octahydro-α，α，4a，8-tetramethyl-，［2R-cis］-(3.04%)；［+］-4-carene(2.81%)；D-limonene(2.71%)；β-myrcene(2.59%)；cedrol(2.40%)；α-pinene(2.36%)；7-isopropyl-1，1，4a-trimethyl-1，2，3，4，4a，9，10，10a-octahydrophenanthrene(2.32%).
