Abstract:
Two new selaginellin derivatives selaginellin P (1) and selaginellin Q (2) were isolated from Selaginella tamariscina. The structures of 1 and 2 were established as 2,4'-dihydroxy-4-methyl-3-[(4-hydroxyphenyl)ethynyl]biphene (1) and 2,4'-dihydroxy-3-[(4-hydroxyphenyl)ethynyl]biphene (2) on the basis of spectroscopic means including HR-ESI-MS, 1D, and 2D NMR experiments.
