RESUMO
A new phenolic glucoside was isolated from the aerial parts of Origanum tyttanthum, an Uzbek medicinal plant, together with 12 known compounds. The structure of the new compound was elucidated as 4-O-beta-D-glucopyranosylbenzyl-3'-hydroxyl-4'-methoxybenzoate (1) based on the spectral and chemical evidence.

Two new icetexane diterpenes, cyclocoulterone (1) and komaroviquinone (2), and a novel 20-norabietane diterpene, dracocephalone A (3), were isolated from Dracocephalum komarovi. Their structures were elucidated by extensive analyses of spectral data. Komaroviquinone (2) showed strong trypanocidal activity against epmastigotes of Trypanosoma cruzi, the causative agent of American trypanosomiasis, with a minimum lethal concentration of 0.4 micro M.
