Description
A further alkaloid obtained from the leaves and stem bark of Capuronetta eiegans, the strucutre of this base has also been established by chemical and spectroscopic methods. It forms colourless crystals when purified by recrystallization from MeOH and has a specific rotation of [α]D20 + 70° (c 1.0, CHCI3). The ultraviolet spectrum in EtOH has absorption maxima at 229,286 and 293 nm. The base may be characterized as the O-acetate which crystallizes as colourless needles from MeOH with m.p. 135°C. The structure given shows that capuronine is an isomer of velbanamine.
