TL;DR: Gastrol (1), together with 10 known phenolic compounds, has been isolated from the MeOH extract of the rhizomes of Gastrodia elata Blume (Orchidaceae), and their structures were elucidated by detailed spectral analyses including by 2D NMR spectroscopic analyses.
TL;DR: Two new phenolic compounds, gastrodin A and gastrol A, together with 7 known ones, have been isolated from the EtOH extract of the rhizomes of Gastrodia elata Blume (Orchidaceae), and their structures were elucidated by spectroscopic analysis and comparison of their spectral data with those reported previously.
TL;DR: Two new phenolic compounds isolated from the rhizomes of Gastrodia elata showed potent neuroprotective activity against H2O2-induced PC12 cell damage and their structures were elucidated on the basis of spectroscopic data and chemical reaction.
