FRAGMENTACIÓN DIASTEREOESPECÍFICA EN NCI DE DOS LIGNANOS DIBENCILBUTÁNICOS DE LA CORTEZA DE Dugandiodendron argyrotrichum (MAGNOLIACEAE)
Two dibenzylbutane lignans, dihydroguairetic acid and austrobailigan-6 were isolated as mixture of their diastereoisomers from the bark ethanolic extract of Dugandiodendron argyrotrichum (Magnoliaceae), a colombian endangered species. Characterization was achieved by 1 H and 13 C NMR, DEPT, COSY, HMQC, HMBC and GCMS analysis. The diastereoisomer separation by GC and the diastereospecific fragmentation patterns in negative chemical ionization mass spectrometry (NCI-MS) spotlights on an interesting tool for stereochemical research.
