The alkaloids skimmianine, evoxine, haplopine, glycoperine, 7-isopentenyloxy-γ-fagarine, haplamide, haplamidine, and haplatine have been isolated from the plant Haplophyllum Latifollium Kar. et Kir. growing in the Chimkent oblast. It has been shown that haplatine has the structure of 7-(3′-hydroxymethylbut-2′-enyloxy)-4,8-dimethoxyfuranoquinoline. It has been established that the qualitative and quantitative compositions of the alkaloids of the epigeal part of the plant change little from the period of flowering to the end of the vegetation season, but depend greatly on the growth site. © 1979 Plenum Publishing Corporation.
