摘要
Two new rearranged diterpenoids, tomocinol C （1） and spirocaesalmin C （2） were isolated from the seeds of Caesalpinia sappan. Their structures were elucidated based on comprehensive analysis of spectroscopic data, and their absolute configurations were established by single crystal X-ray crystallography.
