New diterpenoids from Caesalpinia species and their cytotoxic activity.


PMID 20356735

Abstract

Chemical investigation on Caesalpinia crista afforded two new diterpenoids, 6beta-cinnamoyloxy-7beta-acetoxyvouacapen-5alpha-ol and 6beta,7beta-dibenzoyloxyvouacapen-5alpha-ol and on Caesalpiniapulcherrima another new diterpenoid, 12-demethyl neocaesalpin F along with several known constituents. The structures of the new compounds were settled from their 1D and 2D NMR spectral data. The cytotoxicity of these compounds was measured on two different cancer cell lines.
