Trypanocidal activity was found in the volatile oil of dried Dracocephalum kotschyi. GC-MS analysis determined that the major constituents of the oil were geranial (35.8%), C10H14O (26.6%), limonene (15.8%) and 1,1-dimethoxy decane (14.5%). In order to isolate the unknown biologically active monoterpene, fractionation of the volatile oil was carried out by silica gel column chromatography. The ...

From the whole plant of Dracocephalum kotschyi BOISS., two new monoterpene glycosides (9, 10), together with seven known terpenoids and a phytosterol (1-8), were isolated.
