Abstract:

The scavenging effect of the essential oil from Angelica dahurica roots as a potential antioxidant on 1,1-diphenyl-
2-picrylhydrazyl (DPPH) radical was evaluated. The essential oil was obtained by steam distillation with a yield of 0.52%.
A total of 48 constituents were detected by gas chromatography-mass spectrometry (GC-MS), and 38 of these constituents
were identified as 16 non-terpenoids and 22 terpenoids. The abundant components included cyclododecane (38.705%),
1-pentadecanol (16.781%) and eugenol (11.559%). The oil could obviously scavenge DPPH radical, and maximum
scavenging rate of 95.09% was observed at a concentration of 32.93 mg/mL.

Key words: Angelica dahurica, essential oil, steam distillation, DPPH radical, gas chromatography-mass spectrometry (GC-MS)
