Abstract

Ten new furanocassane-type diterpenes named, caesalpinins H—P (1—9) and norcaesalpinin F (10), were isolated from the CH₂Cl₂ extract of the seed kernels of Caesalpinia crista, together with 13 known diterpenes. Their structures were determined based on the spectroscopic analysis. Among the isolated compounds, caesalpinin N (7) represents the first example of furanocassane-type diterpene possessing an aldehyde group at C-14.
