Abstract
Five new 1β-angeloyloxyeremophilanolides (subspicatins H-L) and 1β-angeloyloxytetranoreremophilanone (norsubspicatin A), were isolated from the EtOAc extracts of Parasenecio petasitoides and their structures established on the basis of spectroscopic analyses. They are biogenetically mutually related to each other and represent a new category in the Parasenecio group. These findings suggest that there is diversity in this species, too.
