title: Complete assignments of (1)H and (13)C NMR spectral data for arylnaphthalene lignan lactones.
abstract: In this work we describe the complete (1)H and (13)C NMR analyses of three arylnaphtalene lignan lactones (taiwanin C, 4-methyl dehydroretrodendrin and justicidin B) using modern NMR techniques such as gCOSY, nonedited gHSQC, gHMBC and NOE experiments. Complete assignment and homonuclear hydrogen coupling constant measurements were performed.
