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 ...

dracocephalum kotschyi (lamiaceae), as one of the remarkable aromatic plants, widely grows and also is cultivated in various temperate regions of iran. there are diverse reports about the composition of the oil of this plant representing limonene derivatives as its major compounds. there is no report on cloning of mono- or sesquiterpene synthases from this plant. in the present study, the aroma...

Phytochemical screening was carried out on the ethylacetate portion of the ethanolic extract of the leaves of Pseudocedrella kotschyii and then evaluated for its analgesic (acetic acid-induced writhing) and anti-inflammatory (raw egg albumin-induced oedema) activities in mice and rats respectively. Phytochemical screening of the ethylacetate partition portion of ethanolic extract revealed the p...

The genus Tanacetum L. is one of the most important medicinal plant that contains 28 species in Iran, 12 of them are endemics. This paper reports the essential oil composition of Tanacetum hololeucum (Bornm.) Podlech; Tanacetum kotschyi (Boiss.) Grierson, growing wild in Iran. Plant flowers were collected from different zones of Dizin in north of Iran. All samples were hydro-distilled (Clevenge...
