Extraction and Isolation. The air-dried, powdered pericarps of C.
bonduc (9.8 kg) were extracted with 95% EtOH (3 × 25 L) at room
temperature (72 h each). Concentration of the combined percolates
under reduced pressure yielded a dark brown crude extract (360 g).
The extract was suspended in H2O and partitioned with petroleum
ether and EtOAc, successively, to yield a petroleum ether (115 g) and
a EtOAc (40 g) extract, respectively.
