Abstract
This work aims to study the effect of different host species on physicochemical and biological properties of the Saharan parasitic plant Cistanche violacea that grows parasitized on two hosts Haloxylon articulatum and a Limonistrum guyonianum in the eastern desert of Algeria. The physicochemical characteristics of C. violcea showed an affinity for the results of both ash and pH and it showed a difference in the amount content of carbohydrates and the value of electrical conductivity. For the content of polyphenols, flavonoids, anthocyanins and tannins the highest values were recorded in C. violcea, which was parasitized on H. articulatum. While, the results of HPLC have identified nine compounds in the crude extracts of the parasitic plants and their hosts in different concentrations. In antioxidant activity, the tannin and anthocyanin extracts from C. violcea parasitized on H. articulatum showed better inhibition of DPPH• radical and best the total antioxidant capacity respectively, but the tannins extract of C. violcea parasitized on L. guyonianum given best reducing power capacity. In SPF assay by UV-Vis spectrophotometry method, all extracts of the parasitic plants showed mild to moderate sun protection. Statically the host variation did not show any significant differences in the physicochemical analysis and the quantitative and qualitative total content of polyphenols. While the significant differences appeared through the antioxidant activity tests, especially between C. violcea and its host H. articulatum, between C. violacea and its host H. articulatum and between the two samples of parasitic plants.
