Abstract

The alkaloid nitraraine and four new bases have been isolated for the first time from the epigeal part ofNitraria komarovii. Their structures have been established with the aid of chemical transformations and spectral characteristics: tetrahydronitramarine, tetrahydrokomarovinine, dihydroisokomarovine, and tetrahydroisokomarovine. Passages have been effected to nitramarine, komarovinine, isokomarovinine, and komarovidinine. Tetrahydroisokomarovine is a new alkaloid, while this is the first time that tetrahydronitroamarine, tetrahydrokomarovinine, and dihydroisokomarovine have been found in nature. Nitrarine, isonitrarine, and schoberidine have been isolated from the seeds with fruit.
