  Glycosidic Constituents of the Tubers of Gymnadenia conopsea

  摘要：

  Ten minor new glycosidic constituents (1-10), together with 10 known compounds, have been isolated from a neuroprotective fraction of an ethanolic extract of the tubers of Gymnadenia conopsea. The structures of 1-10 were determined using spectroscopic and chemical methods. The compounds isolated were evaluated for activity in in vitro assays for acetylcholine esterase and monoamine oxidase inhibitory activities.
