Seco-labdane type diterpenes from Excoecaria agallocha.
Labdane-type diterpenes, called excoecarins S, T1, and T2 were isolated from the resinous wood of Excoecaria agallocha, along with three known compounds, ent-12-oxo-2,3-secobeyer-15-ene-2,3-dioic acid, agallochin H, and ent-15-epoxy-beyerane-3alpha-ol. Their structures were elucidated on the basis of spectroscopic data, chemical evidence, and X-ray analysis.
