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...

In this study, the antimicrobial activity of Myricaria germanica (L.) Desv., Centaurium erythraea Rafn subsp. turcicum (Velen.) Melderis, Prunella vulgaris L., Pelargonium endlicherianum Fenzl., Chrysophthalmum montanum (DC) Boiss. and Jurinea ancyrensis Bornm., were investigated. The antimicrobial activity were evaluated according to the disk diffusion method by using Bacillus megaterium DMS 3...

Scorzonera amasiana Hausskn. and Bornm. was described from type specimens collected by J.F.N. Bornmueller in 1889 but it was not collected again until 1993, when it was found near Amasya, Turkey. Populations of S. amasiana were quite small at that limited locations and were vulnerable to human impacts. Therefore, suitable conservation strategies should be developed immediately in order to prote...
