| Abstract: | The total alkaloids of the roots ofConvolvulus subhirsutus collected in the period of vigorous growth close to the village of Dzhilga, Chimkent province, have been studied. From the
phenolic fraction of the total alkaloids of this species of plant we have isolated phyllalbine and convolidine for the first
time. From the nonphenolic fraction of the combined bases we isolated convolvine, which has been found previously, the new
alkaloid confoline, and an unidentified base (III). On the basis of spectral characteristics and some spectral transformations
it has been established that confoline has the structure of (+)-N-formylconvolvine.
