A new flavone called juncione and known flavone derivatives cynaroside and jaceosidin were isolated from the aerial part of Artemisia juncea Kar. & Kir. The structure 5,6,4′-trihydroxy-3′,5′-dimethoxyflavone 7-O-β-D-glucopyranoside was established for juncione based on IR, UV, PMR, and 13C NMR spectral data and HSQC and HMBC experiments.
