Two new cassane diterpenoids from the seeds of <I>Caesalpinia sappan</I> Linn

Aim null To study the chemical components of the seeds of Caesalpinia sappan. null null null Methods null Compounds were isolated and purified by column chromatography. Their structures were elucidated on the basis of spectroscopic methods. In addition, the cytotoxic activity of these compounds were evaluated using SF-268, MCF-7 and HepG2 cell lines by the MTT assay. null null null Results null Four cassane diterpenoids were obtained and their...
