Abstract |
: |
Genus Commiphora belongs to the family Burseraceae. Commiphora have more than 200 species, about five species are growing in Al-Bahah region, in the southwestern part of the kingdom of Saudi Arabia, these species are: C. gileadensis, C. habessinica, C. kataf, C. myrrha, C. quadricincta. The results showed morphological characters of plants under the study that, there are major and minor characters which put the plants studied into two groups. First group was characterized as the plants not spine includes species: C. gileadensis, C. kataf, the second group included the plants spine species: C. habessinica, C. myrrha, C. quadricincta. The anatomical characters of species stems under study could divide the species into two groups: the first is Axial parenchyma present including C. quadricincta, C. habessinica, C. kataf. The second group include C. gileadensis and C. myrrha characterized by Axial parenchyma absent. The biochemical studies of stems, leaves, and resins for the five plants were recorded, that can be used in the differentiation of the species. It was clear from the data of antioxidant activities inhibition % of DPPH that the Commiphora leaves displayed higher activity than the stems and resins, as well as the total phenolic content of the Commiphora resins displayed higher activity than the stems and leaves. The antimicrobial activities against the tested pathogenic bacteria (gram positive and negative) and fungal, lead us to divide the plants into the same two groups. It has been built a taxonomic key was made based on the morphological and anatomical characters with the conformation by the biochemical characters of the plants under study. |
