Abstract: In order to explore the antibacterial activity of essential oil from Artemisia scoparia and its active ingredient terpinen−4−ol against Aspergillus flavus and its application prospects in the storage and preservation of peanuts, the composition of essential oil from A. scoparia were detected by gas-phase mass spectrometry (GC−MS); Fumigation method was used to detect the effects of essential oil from A. scoparia and terpinen−4−ol on A. flavus mycelial growth and mold counts in peanuts; Scanning electron microscope (SEM) was used to observe the effects of essential oil from A. scoparia and terpinen−4−ol on A. flavus influence of microstructure. The results showed that essential oil from A. scoparia contains 24 compounds, the main component of which is eucalyptol (43.8%), the content of terpinen−4−ol in A. scoparia essential oil was 2.81%; Essential oil from A. scoparia and terpinen−4−ol can significantly inhibit the growth of A. flavus hyphae, and cause the hyphae to shrink, twist and dent; In vivo antibacterial experiments found that essential oil from A. scoparia and terpinen−4−ol can significantly reduce the number of mold in peanuts.

Key words: essential oil from Artemisia scoparia, component analysis, terpine-4-ol, Aspergillus flavus, antifungal activity
