【 摘 要 】

The present study aimed to investigate and reassess the taxonomic relationships of 9 species inPolygonaceae family; Persicaria senegalensis (Meisn.) Soják., Persicaria salicifolia (Brouss. ex Willd.) Assenov.,Rumex dentatus L., Rumex vesicarius L., Calligonum polygonoides L., Antigonon guatimalense Meisn.,Antigonon leptopus Hook. & Arn., Ruprechtia laxiflora Meisn. and Ruprechtia salicifolia (Cham. & Schltdl.) C.A.Mey. using electrophoresis of storage seed protein and analysis of fatty acids composition of seed oils.Clustering analysis was used as a tool in the identification and in evaluation of the taxonomic relationshipsamong the studied species. The total number of recorded protein bands was 21 bands varied from plant toanother ranging between 9 –15 for each species. Protein molecular weight ranged from 4.5-93 kDa. There were4 common bands in all studied species. Rumex dentatus was characterized by the presence of the largestnumber of protein bands. The oil extracts of the studied species included 7 saturated fatty acids and 4unsaturated fatty acids. Palmetic acid, linoleic acid and arachidic acid were the main fatty acids while myristicacid, palmetoleic acid, margrinic acid and ligoceric acid were lowest. The 32 characters of phytochemicalanalysis (21 of seed protein bands and 11 fatty acids) were employed in cluster analysis. The dendrogramproduced indicated that the 9 species could be grouped into two major clusters. Each represent a subfamily. The first cluster represented the subfamily Polygonoideae and divided into two sub groups. The second clusterrepresented the subfamily Coccoloboideae and divided into two groups. The numerical cluster analysis of seedprotein electrophoresis and fatty acids compositions considered Polygonoideae and Coccoloboideae as twoseparate subfamilies.
