| Description | This second alkaloid obtained from the fruit of Alstonia venenata is the 3-methoxy
derivative of the preceding base. It also forms colourless crystals from MeOH and
has a specific rotation of [α] D - 444.5° (c 0.3, CHC13). The ultraviolet spectrum
in ethanolic solution has absorption maxima at 205, 252, 301 and 325 nm with a
shoulder at 220 nm. | | References | Majumder et at., Tetrahedron, 30, 2761 (1974) |
