Chemical constituents and diversity of Ligularia lankongensis in Yunnan Province

Le résumé fourni par la source

The chemical constituents of the roots of Ligularia lankongensis collected at seven different places in Yunnan Province, China, were investigated together with the DNA sequence of the atpB-rbcL intergenic region. All the samples contained a new, highly oxygenated bisabolane-type sesquiterpene (1). Four other oxygenated bisabolanes (2 and the new 3, 4, and 5) were also obtained. Intraspecific diversity was observed in the composition of the compounds, but not in the DNA sequence.
