|Title:||Ei/ms Fragmentation Of Abieta-8, 11, 13-triene Diterpenoid Derivatives As A Tool To Identify Swartziarboreols In Swartzia Extracts|
|Abstract:||A systematic molecular fragmentation pathway (SMFP) was designed as an identifier to detect swartziarboreols (abieta-8, 11, 13-triene diterpenoid derivatives) in Swartzia extracts. The SMFP was rationalised through the interpretation of the EI/MS of swartziarboreols isolated from S. arborescens and S. langasdorffii and by analogy with the fragmentations observed for previously isolated compounds. Two pairs of swartziarboreol epimers were identified by GC-MS in an extract of S. langsdorffii using SMFP. Acetylation and methylation of the dichloromethane extract furnished, respectively, 3 and 4, which suggested the occurrence of a new natural orthodiphenolic swartziarboreol.
