개요
One of the numerous alkaloids which have been isolated from Vinca rosea L. (Syn. Catharanthus roseus G. Don.), this base yields colourless crystals from MeOH and is strongly laevorotatory with [α]D - 528° (CHCl3) or [α]27D - 432° (CHCI3). The ultraviolet spectrum of the alkaloid in EtOH shows three absorption maxima at 226, 297 and 327 ffi/.l. The suggested structure contains one methoxycarbonyl group, an imino group, a bridge ethyl group and an epoxy ring. The second nitrogen atom is tertiary.참고 문헌
