From the aerial parts of Veronica turrilliana two phenylethanoid glycosides, turrilliosides A and B and a steroidal saponin, turrillianoside were isolated and their structures elucidated as beta-(3,4-dihydroxyphenyl)ethyl-4-O-E-caffeoyl-O-[beta-glucopyranosyl-(1 -> 4)-alpha-rhamnopyranosyl-(1 -> 6)]-beta-glucopyranoside, beta-(3,4-dihydroxyphenyl)ethyl-4-O-E-caffeoyl-[6-O-E-feruloyl-beta-gluc opyranosyl-(1 -> 4)-alpha-rhamnopyranosyl-(1 -> 6)]-beta-glucopyranoside and (23S, 25S)-12 beta,23-dihydroxyspirost-5-en-3 beta-yl O-alpha-rhamnopyranosyl-(1 -> 4))-beta-glucopyranoside, respectively. Furthermore, eight known glucosides are reported namely, catalpol, catalposide, verproside, amphicoside, isovanilloylcatalpol, aucubin, arbutin, and 6-O-E-caffeoylarbutin(6-O-Caffeoylarbutin), the latter two for the first time in the genus Veronica.
