PHENOLIC COMPOUNDS FROM ROOTS OF URTICA DIOICA

Root extracts from Urtica dioica were separated into several classes of compounds by extraction with organic solvents at different pH values.The phenolic fraction was analysed by GC-MS after trimethylsilylation.This procedure allowed the identification of 18 phenolic compounds as well as the detection of eight lignans.The occurrence of some of these substances in this plant was previously unknown.
UNERWARTETE REAKTIONSPRODUKTE VON N-METHYL-N-TRIMETHYLSILYLTRIFLUORACETAMID (MSTFA) MIT ALDEHYDEN
Ende, M.,Luftmann, H.
, p. 5167 - 5170 (2007/10/02)
Aldehydes react with MSTFA (N-methyl-N-trimethylsilyl-trifluoroacetamide) to give E/Z-silylenolethers and surprisingly addition products of the reagent to the carbonyl group.The mass spectra of the MSTFA/aliphatic aldehyde adducts are dominated by a key fragment of m/z 228 formed by elimination of the alkyl part.With MSTFA/aromatic aldehyde adducts this fragmentation is replaced by M-H and M-CH3N.8COCF3 (M-126 amu) ions.
