| Abstract: | The new alkaloid komarovinine has been isolated from the total ether-extracted alkaloids of the epigeal part ofNitraria komarovii. It has also been found among the products of the dehydrogenation of nitrarine by selenium and sulfur. On the basis of the available facts, the structure of one of the isomers of 1-quinolinyl-β-carboline was proposed for komarovinine. A direct comparison with synthetic samples shows the identity of the alkaloid to 1-(quinolin-6′-yl)-β-carboline. 1-(Quinolin-7′-yl)-β-carboline, not previously described in the literature, has been characterized. |
