A new monoterpene-glycoside (2-exo-β-D-glucopyranosyl-1,8-cineol) named bucharioside from the methanol-soluble part and a new sesquiterpenoid (4,10-epoxy-6α-hydroxyguaiane) named buchariol from the hexane-soluble part of Salvia bucharica were obtained. Their structures were elucidated with the help of NMR spectroscopy including 1D and 2D experiments.
