The genus Eremostachys Bunge (Lamiaceae) consists of 30 species distributed from Europe through Central Asia to Pakistan and Afghanistan. Of these, five are known to occur in China [1]. Reports in the literature indicate that essential oils and glycosides of iridoids, phenylethanoids, flavonoids, and diterpenes have been isolated from members of this genus. The limited nature of these reports makes this genus an attractive target for further investigation. In this study, the aerial parts of Eremostachys molucelloides Bunge (syn. E. macrophylla Montbret & Aucher ex Benth.) were collected in Kotayk Province, Armenia, between Garni and Zovashen, near Kotayk. Chromatographic fractionation of the methanol extract of this plant has afforded a variety of compounds including flavonoids, flavonoid glycosides, phenylethanoids , vanillic and p-coumaric acids. The structures of these compounds have been elucidated primarily on the basis of their 1D and 2D NMR spectroscopic data and LC-MS.
