[Observation on scavenging free radical function of Artemisia burning products]
Objective:
To study the pharmacologic action of Artemisia burning products.
Methods:
The extractions of Artemisia burning products were determined by spectrophotometry. The scavenging ability of Artemisia burning products on DPPH was evaluated. The chemical components and structures of Artemisia burning products were analyzed by Gas Chromatography and Mass Spectrometry (GC-MS).
Results:
The scavenging ability of extractions from Artemisia burning products was the strongest. Thirty-six chemical components were detected, and the 5-tert-Butylpyrogallol among them had a stronger anti-oxygen capacity, its scavenging free radical ability was 1.55 times and 1.21 times as strong as VitC and BHT, respectively.
Conclusion:
The scavenging free radical ability of 5-tert-Butylpyrogallol extracted from Artemisia burning products is stronger than the natural antioxidant of VitC and artificial synthetic of BHT.
