文摘
The dried aerial parts of Gentiana depressa were found to contain the known flavones, isoscoparin, 2″-glucosyl isovitexin and 2″-glucosyl isoorientin, the known iridoid loganin, and two new iridoid glucosides: 3″-glucosyl depresteroside and depressine. The last two compounds were characterized at 7-[7-(3-β-glucopyranosyloxy-2-hydroxy-benzoyl)-loganoyl] secologanol and 7-(3-β-glucopyranosyloxy-2-hydroxy-benzoyl) secologanol, respectively, by spectroscopy and chemical transformations.
