Aquaticol, a Bis-Sesquiterpene and Iridoid Glucosides from Veronica anagallis-aquatica

Abstract

Aquaticol, an unusual bis-sesquiterpene was isolated from the medicinal plant Veronica anagallis-aquatica, in addition to 11 known compounds, aucubin, geniposidic acid, mussaenoside, catalposide, verproside, amphicoside, catalpol, boschnaloside, shanzhiside methyl ester, sitosterol and β-stigmast-4-en-6β-ol-3-one. The structure of aquaticol was determined by spectroscopic means and by X-ray crystallographic analysis.
