The genus comprises over 400 species of flowering succulent plants. leaves are used in the treatment of asthma, gastrointestinal ulcers, cardiovascular disease, tumors, burns, and diabetes. They are rich in anthraquinones, such as aloin, aloe-emodin, chrysophanol, aloinoside A, and aloinoside B. The various species of show chemical and morphological similarity and diversity, which depend on the genotype and environmental conditions. In a continuity to our interest in the genus, this study targets the authentication of eight different species, (A) (A) (A) (A) (A), (A) (A), and (A), grown in Egypt by using the technique of random amplified polymorphic DNA. Twelve decamer primers were screened in amplification with genomic DNA extracted from all species, of which five primers yielded species-specific reproducible bands. Out of 156 loci detected, the polymorphic, monomorphic, and unique loci were 107, 26, and 23, respectively. Based on a dendrogram and similarity matrix, the eight species were differentiated from each other and showed more divergence. species prevailed similarity coefficients of 54-70 % by which they could be classified into three major groups. Thus, this technique may contribute to the identification of these species that have great morphological similarity in the Egyptian local markets.
