• Chemical investigation of the basic principles of the leaves of <I>Rhazya stricta</I> Decaisne led to the isolation of a number of indolic bases. The studies on two of these, <I>viz.</I>, rhazinaline and geissoschizine are described. Rhazinaline, a new alkaloid, has been characterised as 16-formyl-16-epistrictamine. A detailed spectroscopical study of geissoschizine, which had not been previously isolated from a plant source, was carried out confirming the previous structural assignment. The isolation of this alkaloid from a plant source is important from a biogenetic viewpoint, since geissoschizine is one of the key preformed intermediates in the biosynthesis of C<SUB>19</SUB>–C<SUB>20</SUB> indole alkaloids.
