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. AIM: To investigate the chemical constituents in the stems of Trigonostemon heterophyllus.
