the taxonomic affinity of six species of crocus (c, cancellatus subsp. damascenus c. almehensis, c. gilanicus, c. sativus, c.pallassi subsp. haussknechtii,c. speciosus subsp. speciosus) from iran were studied usingdifferent electrophoresis techniques. the similarity index of the species was computed by comparison of protein bands of - corm and seed tissues, and the related dendrogms of affinity...

A rust fungi species, Uromyces euphorbiae Cooke & Peck (Pucciniaceae) on Euphorbia cheiradenia Boiss. Hohen. (Euphorbiaceae) is reported for the first time from Malatya Turkey and also as a new host species fungi. The morphological microscopical features of this are described with figures.

Acetone extract of aerial parts of Euphorbia marschalliana collected from Iran has been subjected to different chromatography techniques for fractionation and purification. The stereo-structures of the myrsinol esters 15-O-acetyl-3-O-propionyl-5-O-butanoyl-7-O-nicotinoylmyrsinol (1) and 15-O-acetyl-3,5-O-dibutanoyl-7-O-nicotinoylmyrsinol (2) have been probed using ROESY spectroscopy and modifie...

A free radical scavenging activity guided fractionation of the polar extract from roots of Limonium brasiliense (Plumbaginaceae) led to the isolation of five active compounds including: myricetin 3-O-alpha-rhamnopyranoside (1), (-)-epigallocatechin 3-O-gallate (2), (-)-epigallocatechin (3), (+)-gallocatechin (4) and gallic acid (5). These and other chemical constituents are reported for the fir...

This article investigates the exomorphic characteristics of the achenes which are achene size, color, and surface pattern, and pappus length, and colour. All these characteristics in seven taxa of Asteraceae namely, C. aggregata Fisch. & C.A. Mey. ex DC. subsp. aggregata, C. sivasica Wagenitz, C. polypodiifolia Boiss. var. polypodiifolia, C. polypodiifolia Boiss. var. szowitziana (Boiss.) Wagen...
