Article abstract of DOI:10.1016/S0031-9422(00)81119-X

Key Word Index - Coreopsis microlepis; C. woytkowskii; C. senaria; Compositae; sesquiterpenes; perezone derivatives; pipitzol-like compound; acetylenes. - The investigation of three Peruvian Coreopsis species afforded, in addition to compounds isolated previously from this genus, two new tetraynes and five sesquiterpenes all related to perezone, including a tricyclic ketone with a cedrane skeleton closely related to pipitzol.The structures were elucidated by spectroscopic methods.
