“…Talamali et al (2001) also report this favorable distribution for fecundation in A. halimus. The flower (unisexual and bisexual) and the ovule (campylotropous, amphitropous, and orthotropous) types found in A. mollis confirm results reported for A. halimus (Amel et al, 2007) detailing the diversity of ovule types, flowers, and seeds in the same individual, as well as the variation in radicle position and its effect on flower type (Stutz et al, 1990).…”

Atriplex mollis Desf. (Amaranthaceae), a North African endemic halophytic species, is further described in this study. Phylogenetic analysis based on a combined dataset of ITS and ETS rDNA and atpB-rbcL and trnK cpDNA showed that A. mollis is closely related to the Malta-and Gozo-endemic Cremnophyton lanfrancoi Brullo & Pavone. Given this close phylogenetic relationship, A. mollis is also considered among the oldest species of Atriplex, together with C. lanfrancoi. Molecular data also suggest that A. mollis in North Africa, C. lanfrancoi on Malta Island, and Atriplex cana Ledeb. in Eurasian semideserts constitute a separate clade within the tribe Atripliceae. As an 18-month-old shrub, A. mollis can reach a mean height of 44.06 ± 8.09 cm with a leaf area around 1.24 ± 0.15 cm 2 , and can produce seeds in order of 113.08 ± 28.52 g plant −1. The anatomy of A. mollis shows the presence of male and female developed flowers. Hermaphroditic flowers that may lead to the appearance of male flowers with underdeveloped female organs were rarely found. Three main shapes of ovule (campylotropous, amphitropous, and orthotropous) were found in A. mollis.

“…It is characterized by an intra-and interindividual polymorphism for several floral morphological characters including styles, ovule types and radical orientation according to salinity (Talamali et al, 2007). This plant can provide forage complement with interesting nutritive value during the dry seasons and periods of shortage of grazing resources (Benhammou et al, 2009).…”

Salt-tolerant plants grow in a wide variety of saline habitats, from coastal regions, salt marshes and mudflats to inland deserts, salt flats and steppes. Halophytes living in these extreme environments have to deal with frequent changes in salinity level. This can be done by developing adaptive responses including the synthesis of several bioactive molecules. Consequently, several salt marsh plants have traditionally been used for medical, nutritional, and even artisanal purposes. Currently, an increasing interest is granted to these species because of their high content in bioactive compounds (primary and secondary metabolites) such as polyunsaturated fatty acids, carotenoids, vitamins, sterols, essential oils (terpenes), polysaccharides, glycosides, and phenolic compounds. These bioactive substances display potent antioxidant, antimicrobial, anti-inflammatory, and anti-tumoral activities, and therefore represent key-compounds in preventing various diseases (e.g. cancer, chronic inflammation, atherosclerosis and cardiovascular disorder) and ageing processes. The ongoing research will lead to the utilisation of halophytes as a new source of healthy products as functional foods, nutraceuticals or active principles in several industries. This contribution focuses on the ethnopharmacological uses of halophytes in traditional medicine and reviews recent investigations on their biological activities and nutraceuticals. The work is distributed according to the different families of nutraceuticals (lipids, vitamins, proteins, glycosides, phenolic compounds, etc.) discussing the analytical techniques employed for their determination. Information about the claimed health promoting effects of the different families of nutraceuticals is also provided together with data on their application.

“…in the high plateaus and on the littoral where favourable conditions are regrouped with an intra-and interindividual polymorphism for several floral morphological characters including styles, ovule types and radicle orientation according to salinity [9]. This plant represent a potential source for economical utilisation; it can provide forage sources with a good nutritive value during the dry seasons [10] and periods of shortage of grazing resources.…”

For the first time, we have evaluated the antioxidant properties of principal secondary metabolites of leaves and stems from Atriplex halimus. The leaves methanolic extract contained higher levels of total phenolic (10.12 AE 0.56 mg GAE/g DW) than stems methanolic extract (3.77 AE 0.19 mg GAE/g DW). The leaves flavonoids represented by ethyl acetate and butanolic fractions have more hydrogen donating ability to reducing iron and the higher DPPH radical scavenging activity.
