New bis-secolabdane diterpenoids from Excoecaria agallocha.
Two new bis-secolabdane diterpenoids, excoecarins R1 (1) and R2 (2), were isolated from the resinous wood of Excoecaria agallocha. The structures of 1 and 2 were established on the basis of spectroscopic data interpretation and chemical evidence.
