title: A new citryl glycoside from Gastrodia elata and its inhibitory activity on GABA transaminase.
abstract: A new citryl glycoside, trimethylcitryl-beta-D-galactopyranoside (1) along with a known phenolic compound, gastrodigenin (2) have been isolated from the active fraction of the rhizomes of Gastrodia elata (Orchidaceae). Their structures were elucidated on the basis of spectroscopic data and chemical reaction. 1 inhibited GABA transaminase activity by 56.8% at the final concentration of 10 microg/ml.
