Abstract:
Objective: To study the phenanthrenes from the pith of Juncus setchuensis. Methods: The compounds were separated and purified by column chromatographies amd their structures were elucidated by physicochemical properties and spectroscopic methods. Results: Five compounds were isolated from the 95% ethanol extract from the pith of J. setchuensis, their structures were determined as 8-hydroxymethyl-2-hydroxy-1-methyl-5-vinyl-9, 10-dihydrophenanthrene (1), 4-ethenyl-9, 10-dihydro-1, 8-dimethyl-2, 7-phenan-threnediol (2), effusol (3), dehydroeffusol (4), and 4-ethenyl-9, 10-dihydro-7-hydroxy-8-methyl-1-phenanthrenecarboxylic acid (5). Conclusion: Compound 1 is a new compound without literature report, named 8-hydroxymethyl-2-hydroxy-1-methyl-5-vinyl-9, 10-dihydrophenanthrene.
