title: Three new diterpenoids from Croton laui Merr. et Metc.
abstract: Three new diterpenoids, including one labdane diterpenoid (1) and two cembrane diterpenoids (2-3), were isolated from the aerial parts of Croton laui, along with four known analogues (4-7). Their structures were elucidated by spectroscopic analysis and comparison with literature data. All compounds were evaluated for their cytotoxicity against two tumour cell lines.
