Abstract:
Tissue cell cultures of Delphinium staphisagria L. produced three dianthramide glucosides N-(2'-beta-glucopyranosylsalicyl)-5-hydroxyanthranilic acid methyl ester, N-(2'-beta-glucopyranosyl-5'-methoxysalicyl)-5-hydroxyanthranilic acid methyl ester and N-(2'-beta-glucopyranosyl-5'-hydroxysalicyl)-5-hydroxy-6-methoxyanthranilic acid methyl ester, together with known methyl esters of N-salicylanthranilic acid and N-(2'-beta-glucopyranosyl-5'-hydroxysalicyl)-5-hydroxyanthranilic acid. Structures of the glucosides were established by MS, 1-D and 2-D NMR techniques.
