glucopyranosyl)-29-O-(β-d-glucopyranosyl)-2α, 23-dihydroxyolean-12-en-28-oic acid, was
isolated from Anchusa undulata subsp. hybrida and its structure was deduced by spectral
data. In addition to undulatoside, seven known triterpene glycoside and a flavonoid
glycoside were also isolated for the first time from this plant. The structures have been
identified by spectroscopic and chemical methods. The antimicrobial activities of all extracts …
