Goodyerin is a flavonol glycoside isolated from the whole plants of Goodyera schlechtendaliana which has been used as a substitute for the crude drug, Anoectochilus formosanus. The pharmacological properties of goodyerin were assayed for effects on spontaneous locomotor activity, on
Hepatoprotective aliphatic glycosides 3-(S)-3-beta-D-glucopyranosyloxybutanolide (1) and its congener, 3-(S)-3-beta-D-glucopyranosyloxy-4-hydroxybutanoic acid (2) were isolated as major constituents from the whole plants of three Goodyera species, G. schlechtendaliana Reichb. fil., G. matsumurana
A flavonol glycoside, 3-[[6-O-(6-deoxy-alpha-L-mannopyranosyl)-beta-D- glucopyranosyl]oxi]-5,7-dihydroxy-8-[(4-hydroxy-3,5-dimethoxyphenyl)meth yl]- 2-(3,4-dihydroxypheny)-4H-1-benzopyran-4-one, trivially named goodyerin, was isolated from the whole plant of Goodyera schlechtendaliana, along with
The extract of Anoectochilus formosanus showed significant activity in decreasing the levels of the cytosolic enzymes LDH, GOT, and GPT, and the result demonstrated that A. formosanus possessed prominent hepatoprotective activity against CCl(4)-induced hepatotoxicity. Moreover, in the results of the
