title: Immunosuppressive terpenes from Prinsepia utilis.
abstract: Two new hemiterpenes, utililactone (1) and epiutililactone (2), along with nine known compounds (3-11), 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.
