Abstract:

Essential oil was extracted from the leaves of Zanthoxylum ailanthoides Sieb. Et Zucc. collected from Guizhou
by hydrodistillation, and its chemical composition was analyzed by gas chromatography-mass spectrometry. Meanwhile, the
antioxidant activities and nitrite scavenging activity of the essential oil in vitro under simulated gastric conditions were analyzed. A
total of 52 components were identified from the essential oil with α-phellandrene (21.87%), eucalyptol (13.12%), (-)-terpinen-4-ol
(9.55%), γ-terpinene (8.25%), α-terpinene (6.50%), and (-)-α-terpineol (6.31%) being predominant among them. It had significant
scavenging activity against superoxide anion, hydroxyl and DPPH free radicals, as well as nitrite. Therefore, the essential oil from
the leaves of Zanthoxylum ailanthoides Sieb. Et Zucc. is a natural antioxidant with the ability to scavenge nitrite.

Key words: Zanthoxylum ailanthoides Sieb. Et Zucc., essential oil, chemical components, antioxidant activities, gas chromatography-mass spectrometry
