Aim:
To investigate the chemical constituents in the stems of Trigonostemon heterophyllus.
Method:
The chemical constituents were isolated by column chromatography on silica gel, Rp-18, and Sephadex LH-20, and their structures were elucidated on the basis of spectroscopic analysis.
Results:
Three compounds were isolated and identified as a new diterpene, trigonoheterene B (1), together with two known compounds, trigonostemone (2) and trigonochinene B (3).
Conclusion:
Compound 1 is new. Compounds 2 and 3 showed antibacterial activities.
