Abstract

Two new hemiterpenes, utililactone (1) and epiutililactone (2), along with nine known compounds (311), were isolated from the leaves of Prinsepia utilis. Their structures were elucidated on the basis of spectroscopic data. The isolated compounds showed significant immunosuppressive activities.
