Abstract

From nine species of plants of the family Boraginaceae we have isolated and identified 11 compounds, nine of which have proved to be previously known naphthoquinones — derivatives of shikonin. The structure of the previously unknown δ-lactone of 5-(5′,8′-dihydroxy-1′,4′-naphthoquinon-2′-yl)-t-hydroxy-2-methylpent -2-enoic acid has been established. The qualitative and quantitative compositions of the pigments of the species studied and of groups of plants of the Boraginaceae family have been determined.
