摘要:

为开发白芷精油在抗氧化方面的应用,采用水蒸气蒸馏法提取白芷精油,研究其对1,1-二苯基-2-苦味酰基
(1,1-diphenyl-2-picrylhydrazyl,DPPH)自由基的清除作用。结果表明,白芷精油产率为0.52%;经气相色谱-质谱
分析,共检测出48 种成分,鉴定出38 个成分,其中16 种非萜类化合物,22 种萜类化合物,白芷挥发油的主要成分
为环十二烃(38.705%)、1-十五烯醇(16.781%)、丁子香酚(11.559%)。DPPH自由基清除检测结果显示,白
芷精油能明显地清除DPPH自由基,在精油质量浓度为32.93 mg/mL时清除率最大为95.09%。

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)
