Chemodiversity of Artemisia Dracunculus L. from Kyrgyzstan: Isocoumarins, Coumarins, and Flavonoids from Aerial Parts

Abstract

A new accession of Artemisia dracunculus L., originating from Kyrgyzstan, has been analyzed for the first time regarding organ-specific accumulation of lipophilic compounds. Differences were found between leaves, stems, and inflorescences. Exudates obtained from aerial parts yielded only flavanones (eriodictyol, naringenin and their methyl ethers), while the coumarins herniarin and scoparone and biosynthetically unrelated isocoumarins (artemidin, dracumerin) were found to be tissue components. The chemosystematic significance of observed accumulation tendencies is shortly discussed, and other chemodiversity aspects are briefly addressed.
