An amorphous alkaloid found in Vinca rosea L., this laevorotatory base has
[α]25D - 20° (CHCI3). In EtOH, the ultraviolet spectrum has absorption maxima
at 224, 283 and 291 m/J.. The alkaloid forms a hemisulphate, m.p. 263.5°C and
an amorphous O-acetate. The picrate is obtained in the form of brilliant yellow
needles when crystallized from MeOH, m.p. 216°C.
(16R)-E-Isositsirikine is an indole alkaloid compound from Catharanthus roseus Tissue Cultures IV1[1].
ChEBI: 16R,19E-isositsirikine is an alkaloid. It has a role as a metabolite.
