## Abstract From the roots of __Ligularia virgaurea__, five new eremophilane‐type sesquiterpenes were isolated, including three new eremophilenolides, 6__β__‐(angeloyloxy)‐1__α__,8__β__,10__β__‐trihydroxyeremophil‐7(11)‐en‐12,8__α__‐olide (**1**), 6__β__‐(angeloyloxy)‐1__β__,10__β__‐epoxy‐8__β__‐et
The eremophilane group of sesquiterpenes is characterised by a carbon skeleton which does not obey the well-known isoprene rule, and although a number of examples have been discovered recently2 there are still relatively few known members of this group. We wish to
