The results of the descriptive analysis of morphological traits studied allowed us to describe each variety and estimated the variability associated with each character of the different varieties sampled. The results of the principal Component Analysis (PCA) allowed the distinction of nine groups. Comparison of the data collected for each two-to-two variety and the estimate of the square distance between them showed that there is a highly significant difference between all local varieties. Then the comparison between local varieties and imports allowed the population to be separated into 16 distinct groups. Statistical analysis identified skin color as the primary discriminating factor between local varieties followed by fruit length, apical branching and leaf count per shoot. Statistical analysis of qualitative and quantitative morphological data from the 33 characters in study is to be effective for the distinction of new local varieties.

A collection of 100 plants, spread over five localities in this wilaya, is the subject of this investigation. Twenty-three measurements and 16 phenotypic characters were selected for this study. The effect of the region was studied; this factor was found to have a significant effect on the studied traits. A principal component analysis (PCA) and multiple correspondences analysis (MCA) was performed on the phenotypic characteristics, which revealed inertias corresponding to 18. 93% and 14.439% , 14.02% and 11.59% respectively for the first two principal components. This analysis made it possible to establish remarkable phenotypic differences, which have implications to be considered in the characterization program of this plant.

Qualitative phytochemical examination of the leaf extract showed the presence of alkaloids, tannins and flavonoids of varying intensity. Coumarins, terpenoids and saponins are absent in both plants. Qualitative analysis of total polyphenols, flavonoids and condensed tannins of extracts shows that Atriplex halimus from the El Oued region has a high content of total polyphenols (10.25 ± 1.17 mg GAE/g DW) and tannins (9.23 ±1.09 mg EC/g DW) compared to Tlemcen. However, the high flavonoid content presented by Atriplex halimus from the Tlemcen region (3.09 ± 0.13 mg EC/g DW). The evaluation of the antioxidant activity of the extracts was carried out by three methods: total antioxidant capacity, trapping of the free radical DPPH and iron reducing power, the results obtained show that the extract of Atriplex halimus from Tlemcen reveals an interesting activity compared to that of El Oued with a CI50 = 193.47 ± 1.79µg/mL.

MAPs are defined as all raw organic materials ‎‎(trees, shrubs and herbs) whose active elements of their respective organs (fruits, ‎flowers, leaves, roots, stems, buds, bulbs) are likely to be used.‎ The range of plants applications is vast, since it affects the ‎medical sector (pharmaceutical industry, allopathy, phytotherapy, homeopathy, ‎aromatherapy), that of cosmetics and perfumes, chemistry (detergents, dyes, ‎varnishes, fireworks, etc.) and the agro-food sector (minimally processed products ‎such as infusion plants, spices and dry herbs, etc.).‎Ethnobotanical research estimates there are approximately 50 000 to 70 000 plant ‎species used in traditional and modern herbal medicine around the world (Schippmann et al., 2006). The total amount of MAPs used by the pharmaceutical, ‎cosmetic, chemical and food industries is very difficult to estimate. Globally, more ‎than 35 000 are used by the pharmaceutical, chemical or cosmetic industries according ‎to professionals.  There is growing interest by scientists and the World Health Organization in medicinal ‎plants in many countries, especially in developing countries where access to modern ‎health care is limited.

Comparison of means by Duncan’s least significant test separate accessions into several homogeneous groups.
