title: Selaginellins I and J, two new alkynyl phenols, from Selaginella tamariscina (Beauv.) Spring.
abstract: Selaginellins I (1) and J (2), two new compounds, were isolated from Selaginella tamariscina (Beauv.) Spring and were characterized as (R,S)-4-((2',4'-dihydroxy-4-(hydroxymethyl)-3-((4-hydroxyphenyl)ethynyl)biphenyl-2-yl)(4-hydroxyphenyl)methylene)cyclohexa-2,5-dienone (1) and (R,S)-4-((3-((3,4-dihydroxyphenyl)ethynyl)-4'-hydroxy-4-(hydroxymethyl)biphenyl-2-yl)(4-hydroxyphenyl)methylene)cyclohexa-2,5-dienone (2) on the basis of UV, IR, 1D and 2D NMR, and HR-ESI-MS spectroscopic analysis.
