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...

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. Their structures were determined to be limonen-10-al (1), geranial (2), neral (3), beta-sitosterol (4), oleanolic acid (5), ursolic acid (6), p-mentha-8-en-1,2-diol (7), colosolic acid (8), limonen-10-ol 10-O-beta-D-glucopyra...

objective: dracocephalum kotschyi (lamiaceae family) has been usedin traditional medicine for stomach and liver disorders, headache and congestion. in the present study, we have investigated phytochemical properties and antioxidant activities of dichloromethane, ethyl acetate and methanol extracts of d.kotschyi. material and methods: antioxidant activities of extracts were evaluated using the i...
