The title compound, C(30)H(48)O(3), was extracted from the plant Dracocephalum rupestre Hance. The mol-ecule contains five fused cyclo-hexane rings and one five-membered lactone ring. Inter-molecular O-H⋯O hydrogen bonds between the hydroxyl and carbonyl groups link the mol-ecules into chains along [010]. The absolute structure has not been determined.

Tincture of the dry herb has been used for ages in Uyghur folk medicine to treat heart disease, blood pressure, angina, tracheitis, atherosclerosis, neuralgia, migraine, and headache and toothache. 3 Since the 1970s, 246 compounds, including terpenoids,steroids, flavonoids, alkaloids, lignans, phenols, coumarins, and cyanogenicglucosides, have been identified from the genus Dracocephalum, and t...

The internal transcribed spacer regions of nuclear ribosomal DNA are widely used to infer phylogenetic relationships in plants. In this study, it was obtained the ITS sequences from 24 samples of Araceae in Iran, representing 3 genera: Arum L., Biarum Schott. and Eminium (Blume) Schott. Phylogenetic analyses were conducted by Bayesian inference and maximum Parsimony methods. Cladistic analysis ...

Astragalus L. is a perennial herbaceous genus belonging to the family Fabaceae. Chromosome morphology was defined for the first time in four species of Astragalus namely; A. antalyensis A.Duran & Podlech, A. nezaketae A.Duran & Aytaç, A. cariensis Boiss. & A. schizopterus Boiss. All species contained diploid chromosome numbers of 2n = 16. However, polyploid cells (4x = 32) were also observed in...

Feline calicivirus is one of the surrogate viruses human norovirus. This study aimed to identify virucidal compounds, chemical constituents plants from genus Dracocephalum, which are rich in flavonoids and phenylpropanoid oligomers. Four undescribed including a flavanone glucoside, two stilbenoid glycosides, amide glycoside, as well 17 known were isolated Mongolian Dracocephalum fruticulosum St...

Drude, rectangulum Boiss. & Hausskn., verruculosum C.C.Towns. avromanum (Boiss.&a...

The chemical composition of the essential oils of S. hierosolymitana Boiss. and S. multicaulis Vahl. var. simplicifolia Boiss. collected in Lebanon was studied by means of GC and GC-MS analysis. In all 115 compounds were identified: 82 for S hierosolymitana and 72 for S. multicaulis var. simplicifolia. The presence of carbonylic compounds (17%) characterizes the oil from S. hierosolymitana,whil...
