Abstract:
Chemical constituents and evolutionally neutral DNA sequences of six samples of Cremanthodium lineare Maxim., collected in the Sichuan Province of China, were studied. Three samples produced furanoeremophilanes and the other three, eremophilan-8-ones. The chemotypes were found to be correlated with DNA sequence types, suggesting that the chemical diversity observed has a genetic origin. Production of furanoeremophilanes by a Cremanthodium species suggests an evolutionary relationship between Cremanthodium and Ligularia species, and possibly to related genera.
