J Asian Nat Prod Res. 2011 Apr;13(4):356-60. doi: 10.1080/10286020.2011.558840.

Abstract

Two new selaginellin derivatives, selaginellins K (1) and L (2), were isolated from Selaginella tamariscina (Beauv.) Spring and characterized as 2-formyl-4,4'-dihydroxy-3-[(4-hydroxyphenyl)ethynyl]biphene and 4,4'-dihydroxy-2-methyl-3-[(4-hydroxyphenyl)ethynyl]biphene on the basis of their spectroscopic data including UV, IR, 1D, and 2D NMR as well as HR-ESI-MS spectroscopic analysis.
