Intraspecies diversity in the alkaloid profiles regarding the main alkaloid types (chemotypes) was observed. Tyramine\u2010type protoalkaloids (namely, hordenine and its derivatives) were dominant in 19 populations of <jats:italic>G. elwesii.<\/jats:italic> In other populations of <jats:italic>G. elwesii<\/jats:italic>, the plants accumulated mainly homolycorine\u2010, lycorine\u2010, and galanthamine\u2010type alkaloids. The alkaloid profiles of <jats:italic>G. nivalis<\/jats:italic> were dominated by narciclasine\u2010, galanthamine\u2010, lycorine\u2010, haemanthamine\u2010, or tazettine\u2010type compounds. Geographical distribution of chemotypes indicated a relationship between populations, since adjacent populations often displayed similar alkaloid profiles.
