“…The 13 C and DEPT NMR spectrum showed the presence of 19 signals (Table-1), corresponding to two aromatic rings (C-1-C-6 and C-1'-C-6'), a pair of double bond (C-7' and C-8'), a 3-hydroxypropan-1one moiety (C-7-C-9) 15 , two methoxy groups (δC 55.8, 55.9; δH 3.82, 3.86) and a phenolic hydroxy group (δH 11.22). Based on comparison with 13 C NMR spectral data of 1 with these of the known compound, sobraline 16 , the major differences due to a carboxyl in sobraline replaced by a 3-hydroxypropan-1one moiety in 1. The 1 H NMR spectrum of this compound indicated the presence of a signal at δH 7.08 (s) characteristic .92 (dd, J = 1.8 and 8.5 Hz) and 7.62 (d, J = 8.5 Hz), assigned to the hydrogens H-2, H-4 and H-5, respectively and signals at δH 6.25 (d, J = 2.5) and 6.24 (d, J = 2.5), corresponding to the hydrogens H-3' and H-5', respectively.…”
