“…From spectral data (UV, IR, MS, 1H-NMR, '3C-NMR), the major alkaloid of the seeds was identified as stemmadenine (4) [5]. The other alkaloids were identified as coronaridine (1) [6], ibogamine (2) [7], tabersonine (5) [8], voacangine (3) [9], voaphylline (6) [10,11] by comparison of spectral data (UV, IR, MS, 'H-NMR) and Co-TLC with authentic samples.…”
