Continuing the separation of the combined alkaloids of the epigeal part of Corydalis ledebouriana collected In the Tashkent oblast [I], we have isolated two new bases (1) and lID. There is contradictory information concerning the capacity of callus tissue of Vinca rosea (Madagascar periwinlde) for synthesizing alkaloids. Some workers [1] have obtained tissue capable of biosynthesizing monomeric and dimeric alkaloids, while others [2] have found only moaomeric bases in such tissues. This is the first time that information on the chemical composition of the tissue has been published.
