Iridoid glucosides from Veronica filiformis SM1,2

ABSTRACT

Ethyl acetate soluble fraction of the methanol extract of the fresh aerial parts of Veronica filiformis Sm. yielded eight known iridoid glucosides; namely, aucubin, catalpol, veronicoside, amphicoside, catalposide, verproside, minecoside and verminoside. The isolated compounds were identified by chemical means, acid and alkaline hydrolysis, as well as cochromatography against authentics, and finally full characterized by their spectral data including UV, IR, FAB-MS, [1]H-NMR and [13]C-NMR
