METHODS: The chemical constituents were isolated by column chromatography on silica gel and Sephadex LH-20, and their structures were elucidated on the basis of spectroscopic analysis. RESULTS: Four compounds were isolated and identified as 3α, 3β, 10β-trimethyl-decahydroazuleno[6, 7]furan-8, 9, 14-triol(1), 4-hydroxyphenylacetic acid(2), 4-hydroxyphenethyl alcohol(3), and 5-hydroxymethyl-2-furancarboxaldehyde(4). CONCLUSION: Compound 1 was a new compound. Compound 2 showed antibacterial activity against Staphylococcus aureus.展开更多

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.展开更多
