Loganin and New Iridoid Glucosides inGentiana pedicellata

Abstract
2′-p-Coumaroyl-loganin, 2′-feruloyl-loganin, 2′-caffeoyl-loganin, and the known iridoid loganin have been isolated from flowers and leaves of Gentiana pedicellata (Gentianaceae). This is the first occurrence of iridoid glucosides being reported in this species.
