Abstract:The essential oil from the leaves of Solarium verbascifolium L. was obtained by steam distillation, followed by solvent extraction, and analyzed by capillary GC-MS. The content of essential oil in fresh leaves was 0.0611% after steam distillation 8 hours. Eighteen peaks were detected and 17 compounds were identified, which accounted for 99.73% of the total oil. The main chemical components were germacrene D （37.07%）, copaene （26.29%）, 1β-（1-methylethyl）- 4,7-dimethyl-1α,2,4a（f3）,5,8,8a（α）-naphthalene （13.63%）, caryophyllene （8.03%）, 1 β-ethenyl- 1 or-methyl-2β,4β-bis （1 -methylethenyl）- cyclohexane （5.81%）,γ-elemene （2.16%）, α-cubebene （2.06%） and isoledene （0.98%）, respectively. The above eight compounds accounted for 90.22% of the total oil.
