High Diversity ofLigularia dictyoneura in Chemical Composition and DNA Sequence

The chemical composition of root extracts of the title species collected at 20 different places in the Hengduan Mountains of China was examined. From these samples, a total of 17 eremophilane derivatives were isolated, three of which were new franoeremophilane derivatives: 3 β ‐acetoxy‐6 β ‐(angeloyloxy)furanoeremophilan‐10 β ‐ol, 1 α ‐acetoxyfuranoeremophilan‐15,6 α ‐olide, and 6 β ‐[2‐(hydroxymethyl)prop‐2‐enoyloxy]furanoeremophil‐1(10)‐ene....
