RESUMO
OBJECTIVE: To analyse the chemical constituents of volatile oil from Asarum insigne. METHODS: The volatile oil from Asarum insigne was isolated with steam distillation and identified by capillary GC/MS method. RESULTS: 68 Volatile components were identified and determined, accounting for 92.18% of the total peak area. The main volatile compounds and their relative contents are camphene (13.48%), alpha-pinene (12.44%), beta-pinene (11.07%), borneol (8.12%), trans-beta-farnesene (5.91%), elemicin (5.38%), 1,3-benzodioxole-5-(2-propenyl) (3.06%), myristicin (2.95%), ledene (2.47%), eucalyptol (2.33%), patchouli alcohol (2.25%), alpha-bisabolene (2.04%) and bornyl acetate (1.36%) etc. CONCLUSION: The study provided solid and scientific proof for the exploitation and utilization of Asarum insigne.
