The complete assignments of all the 1 H and 13 C NMR signals of three sesquiterpene lactones, 4‐oxo‐5(6),11‐eudesmadiene‐8,12‐olide (1), 4‐oxo‐11‐eudesmaene‐8,12‐olide (2) and (1(10)E)‐5β‐Hydroxygermacra‐1(10),4(15),11‐trien‐8, 12‐olide (3), were carried out by various 2D NMR experiments. Compounds 1–3 were isolated from the roots of Inula helenium for the first time. Among them, 1 was identified as a new nor‐sesquiterpene lactone, and 2 was isolated from a natural source for the first time. The 13 C‐NMR data of compound 3 was also reported for the first time.
