Selaginellin M, a new selaginellin derivative from Selaginella pulvinata

摘要

A new selaginellin derivative, selaginellin M (1), together with one known compound, selaginellin E (2), was isolated from Selaginella pulvinata. The structure of the new compound was elucidated and named as (R,S)-4-((4'-hydroxy-4-((2-hydroxyethoxy) methyl))-3-((4-hydroxyphenyl)ethynyl)biphenyl-2-yl)(4-hydroxyphenyl)methylene)-cyclohexa-2,5-dienone on the basis of the spectroscopic data including UV, IR, ID, and 2D NMR as well as HR-ESI-MS analysis.
