Constituents of Caesalpinia crista from Indonesia

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...

Beschreibung
Zusammenfassung:	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.
