The high-molecular water-soluble preparations from several species of two genera (Symphytum and Anchusa) of Boraginaceae family Symphytum asperum, S. caucasicum, S.officinale and Anchusa italica were isolated. According to IR, C and H NMR, APT, 1D NOE, 2D heteronuclear H/C HSQC and 2D DOSY experiments, the main chemical constituent of these preparations was found to be caffeic acid-derived poly...
With its four species, Anchusa is one of the weedy genera of Boraginaceae in Iran. Its species are distributed in different habitats. In this study, the fruit morphological and micro-morphological features of the Anchusa taxa have been considered, so as to evaluate their diagnostic value. Eight qualitative and quantitative fruit features from 12 accessions of A. italica, A. strigosa, A. arvensi...

According to IR, 13C and 1H NMR, APT, 1D NOE, 2D heteronuclear 1H/13C HSQC and 2D DOSY experiments the main chemical constituent of high-molecular preparations from Symphytum asperum, S. caucasicum, S. officinale and Anchusa italica (Boraginaceae) was found to be caffeic acid-derived polyether, namely poly[3-(3,4-dihydroxyphenyl)glyceric acid] (PDPGA) or poly[oxy-1-carboxy-2-(3,4-dihydroxypheny...
the present study reports the chromosome number and meiotic behaviour of 14 populationsbelonging to four taxa of anchusa subgenus buglossum gusul. from iran. all populationsshowed the chromosome number 2n= 4x= 32. it is the first meiotic study for a. subg.buglossum. we discuss some habit form and evolutionary aspect in the light of cytogeneticdata. the origin of polyploidy (auto-allopolyploidy)...

The presented special communication summarizes data concerning novel caffeic acid-derived polyether from the species of two genera (Symphytum and Anchusa) of Boraginaceae family Symphytum asperum, S. caucasicum, S. officinale and Anchusa italica and structure elucidation of its main structural element. The high-molecular fractions were isolated from crude polysaccharides by ultrafiltration on m...
Honey samples (n = 126) from Castilla-La Mancha (Central Spain) were characterized based on their physicochemical properties and a melissopalynological analysis. The latter showed that Echium pollen type was the dominant palynomorph in most samples, representing at least 30% of the pollen in each sample. As anticipated, a relationship was observed between the proportion of this pollen and the p...
anchusa )boraginaceae( includes weedy species in different habitats and cultivations and is composed of four species in iran. species delimitation is mainly based on features as zygomorphic or actinomorphic flowers, straight corolla tube and nutlet shape. in this project, morphological features of different accessions of anchusa species were evaluated. totally, 33 qualitative and quantitative m...
