Enhanced Synthesis of Volatile Compounds by UV-B Irradiation in <i>Artemisia argyi</i> Leaves.

ABSTRACT: Background: Volatile compounds have a deep influence on the quality and application of the medicinal herb Artemisia argyi; however, little is known about the effect of UV-B radiation on volatile metabolites. Methods: We herein investigated the effects of UV-B exposure on the volatile compounds and transcriptome of A. argyi to assess the potential for improving its quality and medicinal characteristics. Results: Out of 733 volatiles obtained, a total of 133 differentially expressed metabolites (DEMs) were identified by metabolome analysis. These were classified into 16 categories, primarily consisting of terpenoids, esters, heterocyclic compounds, alcohols, and ketones. Sensory odor analysis indicated that green was the odor with the highest number of anno
