“…Recently, several scientific reports on the health benefits and nutritional potential of bioactive compounds from this jujube have been reported (Abcha et al, 2021;Letaief et al, 2021). This plant is rich in polyphenols, cyclopeptide alkaloids, dammarane saponins, vitamins, minerals, amino acids and polyunsaturated amino acids (Souleymane, 2016).…”

This study compares the various knowledge of the use of Ziziphus lotus L. in a semi-arid zone in the west of Algeria (Relizane province). The ethnobotanical survey used semi-structured interviews carried out on 300 people in four different localities. The final matrix was processed using the appropriate statistical methods for the different types of variables (quantitative and qualitative). The hierarchical ascendant classification reveals a high diversity of the use of Ziziphus by the local population (therapeutic and cosmetic). The Results indicate that the use of the plant is almost therapeutic (75%) whereas the most used parts are leaves (70,33 %) and fruits (19,66 %). The plant is much more used in cases of pain and fever with a percentage of 41,33 %. It is also used for gastrological and respiratory diseases. The analysis of variance revealed significant differences for all the analyzed parameters. This is explained by the fact that the plant is used in different ways for different diseases with different modes. It was concluded that the inventory interview was the most effective method to better inform the local population's know-how, as it allowed for the identification, It is recommended to intensify the ethnobotanical investigations to trace the phytotherapeutic path of the species.

“…The reproductive phase of this species is characterized by the appearance of a drupe fruit, brown when ripe, within a shrub with multitudes of densely foliated branches. The fruits, locally known as 'Nbeg', are edible either directly or after traditional processing into a flour known as Zemmita (Abcha et al 2021 The best metal adsorption rate is obtained with a temperature ranging from 25°C to 30°C, a contact time of 90 min, an initial ionic concentration of 100 mg/L, and a biosorbent dosage ranging from 3.5 to 5 g/L. The experimental kinetic data of the biosorption process for both heavy metal ions were fitted by the pseudo-second-order model.…”

Ziziphus lotus has been the subject of several researchs because of its nutritional benefits and ecological attributes. The removal of hexavalent chromium Cr(VI) from a solution using powdered Zizphus lotus fruits, for its qualities of being inexpensive as well as environmentally friendly, was investigated. The results obtained showed that at pH = 2, at 30°C, after 600 min of adsorbent/adsorbate contact, with 100 mg/L as initial concentration of Cr(VI) and a biosorbent dosage of 5 g/L, the biosorption of Cr(VI) on Zizphus lotus fruit powder (ZLFP) is at its maximum rate. The sorption process was exothermic (∆H° = -6.69 kJ/mol), and was characterized by a positive entropy values (∆S° = 46.76 J/K mol) suggesting a high affinity of the ZLFP for Cr(VI). Given that the Gibbs free energy (∆G°) is negative and decreases as temperatures increase from 293 to 323 K, the process of biosorption is both feasible and spontaneous. The Temkin model and the Langmuir model both generated excellent fits to the equilibrium data. The maximum monolayer biosorption capacity was 36.11 mg/g. The pseudo second order model was used to fit the kinetic data relating to the adsorption of Cr(VI) on the ZLFP. The FTIR spectral analysis allowed the characterization of the biochemical groups mainly involved in the sorption of Cr(VI) ions on the ZLFP, and which are: N-C, H-O, O-C, H-C, and O=C. The capacity of Ziziphus lotus fruit as an inexpensive, effective, and ecofriendly biosorbent is confirmed through this study.
