title: Leptopyrine, new alkaloid from Leptopyrum fumarioides L. (Ranunculaceae).
abstract: A new type of isoquinoline alkaloid leptopyrine was isolated from the aerial parts of Leptopyrum fumarioides L. (Ranunculaceae) of Mongolian origin. The known alkaloids protopine and thalifoline were isolated for the first time from this the species. All structures were established by physical and spectral analyses.
