title: Glucosyloxybenzyl 2-Isobutylmalates from the tubers of Gymnadenia conopsea.
abstract: Seven new glucosyloxybenzyl 2-isobutylmalates, gymnosides I-VII (1-7), were isolated from the tubers of Gymnadenia conopsea. The structures of 1-7 were determined on the basis of chemical and physicochemical evidence.
