An ellagic compound and iridoids from Cornus capitata root cultures

An ellagic acid derivative, 3,3'-di-O-methylellagic acid 4-(5"-acetyl)-alpha-L-arabinofuranoside, and two iridoid glucosides, 6alpha-dihydrocornic acid and 6beta-dihydrocornic acid, were isolated from Cornus capitata adventitious roots cultured in Murashige-Skoog (Murashige, T., Skoog, F.,...

Zusammenfassung:	An ellagic acid derivative, 3,3'-di-O-methylellagic acid 4-(5"-acetyl)-alpha-L-arabinofuranoside, and two iridoid glucosides, 6alpha-dihydrocornic acid and 6beta-dihydrocornic acid, were isolated from Cornus capitata adventitious roots cultured in Murashige-Skoog (Murashige, T., Skoog, F., 1962. A revised medium for rapid growth and bioassays with tobacco tissue cultures. Physiol. Plant. 15, 473-487) liquid medium containing 10 microM CuSO(4). Three known related metabolites, i.e. stenophyllin H1, dihydrocornin and cornin were also produced in the root cultures. The chemical structures were characterized by analysis of spectroscopic data.
