摘要：
Three cytotoxic cleroodane diterpene esters, corymbulosins A-C, were isolated from an organic extract of the fruit of Laetia corymbulosa (Flacourtiaceae) from Peru. The structures were determined by spectroscopic methods as clerodane diterpenes unsaturated at C-3, C-13(16) and C-14. Corymbulosin A was esterified at C-2 with a decadienoate moiety, while corymbulosins B and C were C-2 epimers esterified at C-6 with a decanoate moiety. (C) 2000 Elsevier Science Ltd.
