They are mostly perennial herbs, and rarely annual. Flora Iranica reports 8 Iran 10 out which, 4 endemic. We collected 7 studied delimitation relationship by morphometric anatomic results. were efficiently delimited...

Background: A number of aromatic medicinal plants used for treating infection disease have been mentioned in different phytotherapy manuals due to their availability, fewer side effects, and reduced toxicity.Dracocephalum L is one of the most important genuses of Lamiaceae.The aim of our study was to evaluate the chemical compositions of Dracocephalum Lind...

introduction: unsaturated fatty acids , one of the most important components of biological membranes , are very sensitive to oxidation processes. damage to cells and tissues by oxidation of these kinds of acids is one of the most important contributing  factors in many diseases, such as, atherosclerosis, rheumatoid arthritis and cancer. there are some available antioxidant synthetic compounds i...

Background and objectives: Dracocephalum species are mentioned in Iranian traditional medicine for enhancement of cognitive performance. In the present study, the acetyl cholinesterase inhibitory and butyryl cholinesterase inhibitory activities as well as the anti-oxidant and anti-tyrosinase effects of three Iranian Dracocephalum species (D. kotschyi,...

The health benefits of Dracocephalum heterophyllum are widely reported in traditional Tibetan medicines, but the chemical composition is limited, probably due to difficulties separating and purifying compounds. In this study, antioxidative phenylethanoids were isolated from an extract using medium- high-pressure liquid chromatography, coupled with on-line HPLC–1,1-diphenyl-2-picrylhydrazyl reco...

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 ...
