Abstract

Lappula myosotis Moench. (Boraginaceae) is a plant growing wide-spread in the Mongolian Aimags Khubsgul, Khangai, Khentei, Mongol dahurica, Altai and Alasha Gobi [1]. From this plant four pyrrolizidine alkloids were isolated and their structures determined using spectroscopical methods: lycopsamine, intermedine and their acetylderivatives. This plant is used in the Mongolian traditional medicine externally but on account of its high level of alkaloids (~ 0.2%) the usage of L. myosotis may be hazardous for humans.
