A monoterpenoid pyridine derivative isolated from the aerial parts of Indian Vinca major L. has been identified as RW 47 (Venoterpine), previously obtained from an Alstonia and a Rauwolfia species, on the basis of spectral evidence and by direct comparison. The genus Vinca (Apocynaceae) is well-documented to be a storehouse of C₁₆-C₂₀ indole alkaloids of diverse structural patterns, many of which are of considerable therapeutic value [1]. So far nearly a hundred such bases have been isolated from different species of this genus [1]. In the course of our studies on the alkaloidal principles of indigenous Apocynaceous plants, we took up the investigation of the plant Vinca major Linn. collected from the Long Islands in the Andamans, situated in the Indian Ocean. Seven alkaloids have so far been isolated from the aerial parts of this plant. The characterisation of five of these, viz. reserpinine, vincamajoreine, majoridine, 10-methoxyvellosimine and the new alkaloid lochvinerine has been reported elsewhere [2]. The present communication reports the identification of the sixth base as the monoterpenoid pyridine derivative RW 47 [3,4] (venoterpine [5, 6]) on the basis of spectral evidence and by direct comparison with an authentic sample.
