Abstract
Six new pyrrolizidine alkaloids, a new carboxylic acid, a new phenolic and a new oleanane glycoside, together with the known compounds 7,7′-bis-(4-hydroxy-3,5-dimethoxyphenyl)-8,8′-dihydroxymethyltetrahydrofuran 4′-O-β-D-glucopyranoside, rosmarinic acid, caffeic acid, tormentic acid 28-O-β-D-glucopyranoside, euscaphic acid 28-O-β-D-glucopyranoside, euscaphic acid, and allantoin were isolated from ANCHUSA STRIGOSA roots. Their structures were established by high resolution NMR, MS, elemental analysis, and chemical reactions.
