Gibberellic acid stimulated transcriptional protein from Gymnadenia conopsea (GcGAST) is a novel member of GA-induced cysteine-rich protein family, which shared 12 highly conserved cysteine residues with other members in C-terminal domain. In the present paper, the recombinant plasmid, as well as
Four new minor constituents including two cyclodipeptides (1 and 2) and two cyclopentene derivatives (3 and 4), together with four known cyclodipeptides, have been isolated from an ethanolic extract of the tubers of Gymnadenia conopsea. Their structures including absolute configurations were
