Eleven phenylpropanoids were isolated from the whole grass of Liparis nervosa, an orchidaceous medicinal plant. Their structures elucidated as (+)-Syringaresinol (1), (-)-Syringaresinol-4-O-?-D-glucopyranoside (2), Sinapaldehyde (3), Coniferyl aldehyde (4), Syringin (5), Sinapaldehye-4-O-?-D-glucoside (6), 2,3-dihydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone (7), C-Veratroylglycol (8), 7...

Flammulina velutipes is the fourth largest edible fungus in China with high nutritional value. In this paper, ultrahigh-performance liquid chromatography tandem hybrid quadrupole-Orbitrap mass spectrometry (UPLC-Q-Exactive-Orbitrap MS) was used to identify secondary metabolites of F. velutipes. The were identified by comparing retention time, accurate molecular weight, and MS2 data standard dat...
