Article

The perennial herbaceous plant Dracocephalum komarovii Lipsky [1] (Lamiaceae) grows in Central Asia on rocky slopes in the upper mountain zone at elevations of 2,300–3,600 m above sea level. Plants of the genus Dracocephalum are used in folk medicine to treat colds, headaches, angina, hypotension, tracheitis, atherosclerosis, heart diseases, bronchitis, neuralgia, migraine, and toothache [2, 3, 4, 5, 6]. Previous studies of the chemical components of D. komarovii isolated diterpenoids that exhibited activity against Trypanosoma cruzi, a vector of Chagas’ disease and American trypanosomiasis in Central and South America [7, 8, 9, 10].

The aerial part of D. komarovii (2 kg) gathered in Tashkent Oblast (Uzbekistan) during flowering was extracted with EtOH (70%) at room temperature. The condensed extract was chromatographed over a column of silica gel using a hexane–EtOAc gradient (16:1, 12:1, 9:1, 4:1, 2:1) to produce pure 1 (10 mg), 2(11 mg), and seven fractions (1–7). Each fraction...
