Two new 2,2-dimethyl-chromene derivatives and the new pentaisovaleryl sucrose were isolated from the roots of Artemisia asiatica together with the known 1-(5-acetyl-2,4-dihydroxy-phenyl)-3-methyl-butan-1-one, 6-hydroxytremetone and (E)-coniferyl aldehyde. The structures of the compounds were elucidated by extensive 1D (1H, 13C and JMOD) and 2D (1H-1H COSY, HSQC, HMBC and NOESY) NMR studies and APCIMS and HRESIMS investigations. 6-Acetyl-3,7-dihydroxy-2,2-dimethyl-chromene and 6-acetyl-3-hydroxy-2,2-dimethyl-chromene are biogenetically related to 1-(5-acetyl-2,4-dihydroxy-phenyl)-3-methyl-butan-1-one and 6-hydroxytremetone as all having isoprenoid acetophenone origin. All the isolated compounds were described for the first time from this species; interestingly none of them are related to the metabolites identified from the extracts of the aerial part of the plant.
