Dracocephalum ruyschiana L. is an Eurasian continental species with a fragmented distribution extending from the boreal regions to Asian steppes and European mountains. In Pyrenees it only known three locations in France, but two of them have not been rediscovered modern times, there are no citations Spain or Andorra. summer 2021 population was found Val d’Aran (Catalan Pyrenees, Spain). A comp...

A composition of taxa included in Dracocephalum imberbe Bunge s. l. is discussed. Species rank D. laniflorum Rupr. reinstated based on the following characters: underground part represented by a system branching rhizomes, bracts absent, calyx 12–14 mm long, with triangular or narrowly triangular, pointless teeth, middle tooth upper lip up to 1.5 times wider than lateral ones and plant being nea...

The genus Dracocephalum L. (Lamiaceae) with about 60 to 70 species is a in the sub-tribe Nepetinae, tribe Mentheae of Lamiaceae family, native temperate regions Northern Hemisphere. 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...

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...
