Abstract
ABSTRACT
Hydrosols from
Artemisia argyi
and
A. lavandulifolia
collected across different regions and seasons in Shandong Province, China, were comparatively analyzed for chemical composition and antibacterial activity. GC–MS results showed that
A. lavandulifolia
hydrosol contained higher levels of terpinen‐4‐ol and α‐terpineol and exhibited a chemical profile distinct from
A. argyi
. Variations in key volatile compounds suggested influences of harvest season and geographic origin. Antibacterial assays against five bacterial strains showed that both hydrosols inhibited
Escherichia coli
ATCC 25922 and
Proteus vulgaris
ATCC 49132, with
A. lavandulifolia
displaying stronger activity. Multivariate analyses, including HCA, PCA, and heatmaps, further supported species‐related differences with partial sample overlap. These findings highlight the compositional and bioactive diversity of
Artemisia
hydrosols and their potential as natural antimicrobial agents.
