Abstract
A new flavone glycoside, 6-hydroxyluteolin 7-O-[6m-benzoyl-β -D-glucopyranosyl-(1 → 2)]-β - D-glucopyranoside (aphyllanthoside, 1) was isolated from the MeOH extract of the aerial parts of Globularia aphyllanthes. Besides this new compound, two flavonoid glycosides (6-hydroxyluteolin 7-O-[6m-(E)-caffeoyl-β -D-glucopyranosyl-(1 → 2)]-β -D-glucopyranoside and isoquercitrin), three phenylethanoid glycosides (verbascoside, rossicaside A, and trichosanthoside A), and 11 iridoid glycosides (aucubin, catalpol, 10-O-benzoylcatalpol, globularin, asperuloside, besperuloside, asperulosidic acid, daphylloside, scandoside, alpinoside and baldaccioside) were also obtained and characterized. Identification of the isolated compounds was carried out by spectroscopic analysis including 1D and 2D NMR experiments as well as HRMS
