Abstract: Essential oil was extracted by steam distillation from Ligusticum chuanxiong Hort leaves and analyzed by gas chromatography-mass spectroscopy (GC-MS). Totally 84 and 51 compounds were identified in essential oils from Ligusticum chuanxiong Hort leaves harvested in spring and summer, with a relative content of respectively 97.8% and 98.2%. No significant difference in chemical composition was observed between essential oils from the leaves harvested at both seasons. The major components were 3,4-dimethylenecyclopent-anone, 5,7,8-trimethyl-2-chromanone, caryophyllene, trans-ocimene, cis-ocimene, (+)-sabinene and α-pinene.
