“…Although they do not provide nectar, they are essential for pollen in describing the geographical origin [ 26 ]. Our results are similar to those from the Steppe region in Algeria, which is also characterized by a hot and dry climate [ 40 , 41 ]. However, Myrtaceae, Apiaceae, and Ericaceae families are most frequently found in honey samples in the Algerian north [ 42 ].…”

Despite the challenging conditions in the pre-Saharan areas of Algeria, such as weak plant cover and a harsh climate, beekeeping is being developed and spread. In the present work, honey samples collected from ten locations in the El Oued region were examined during the spring of 2021. A melissopalynological analysis was carried out, followed by a floristic investigation. The 10 honey samples were also investigated for their physicochemical properties and antioxidant and antibacterial activity against five strains: Escherichia coli, Staphylococcus aureus, Bacillus subtilus, Listeria innocua, and Micrococcus luteus. The floristic analysis found 65 species belonging to 33 botanical families, with a dominance of the Asteraceae family accounting for 18.461% of the total. The melissopalynological study revealed only one monofloral honey (Ziziphus lotus), whereas the nine others were multi-floral. The honey’s color changed from light to dark amber, and most tested honey was of high quality, fulfilling international criteria. The total phenol and flavonoid contents varied considerably amongst the various honey samples. Furthermore, LC-MS-MS phenolic profile analysis identified the presence of 20 chemicals, of which only three phenols were found in all honey types. Antioxidant capacity analyzed with FRAP test and antiradical activities against DPPH differed from one honey sample to another. Moreover, a significant correlation was recorded between the antioxidant activity, honey’s color, polyphenol, and flavonoid contents. The S. aureus strain was the most sensitive regarding honey antibacterial activity, while M. luteus and B. subtilis strains were only moderately sensitive.

“…PGs from the same plant sources were identified in Ziziphus honey in another study by Taha et al (2018). The pollen variety in Algerian honey revealed that Ziziphus lotus pollen was the predominant species foraged by honeybees for honey production, with a mean value of 70.9% (Zerrouk et al, 2021).…”

The increasing demand for honey purification and authentication necessitates the global utilization of advanced processing tools. Common honey processing techniques, such as chromatography, are commonly used to assess the quality and quantity of valuable honey. In this study, 15 honey samples were authenticated using HPLC and GC–MS chromatographic methods to analyze their pollen spectrum. Various monofloral honey samples were collected, including Acacia, Hypoestes, Lavandula, Tamarix, Trifolium, and Ziziphus species, based on accurate identification by apiarists in 2023 from the Kingdom of Saudi Arabia. Honey analysis revealed the extraction of pollen from 20 different honeybee floral species. Pollen identified from honey samples using advanced chromatographic tools revealed dominant vegetation resources: Ziziphus species (23%), Acacia species (25%), Tamarix species (34%), Lavandula species (26%), Hypoestes species (34%), and Trifolium species (31%). This study uses HPLC to extract phenolic compounds, revealing dominant protocatechuic acid (4.71 mg g−1), and GC–MS to analyze organic compounds in honey pollen. Specifically, 2‐dodecanone was detected with a retention time of 7.34 min. The utilization of chromatographic tools in assessing honey samples for pollen identification provides a reliable and efficient method for determining their botanical origins, thereby contributing to the quality control and authentication of honey products.

Description du sujet. En Algérie, le miel de jujubier a une importance socioéconomique et thérapeutique. En l’absence de normes de qualité, il est souvent exposé aux pratiques frauduleuses sur son appellation d’origine et sa qualité. Objectifs. Identifier les caractéristiques polliniques, déterminer le spectre pollinique permettant de spécifier les miels de jujubier d’Algérie ainsi que les caractères morphologiques du pollen de Ziziphus lotus (L.) Lam. Méthode. Quarante échantillons de miel de Z. lotus ont été soumis aux analyses polliniques qualitative et quantitative selon les méthodes préconisées par la commission internationale de botanique apicole. La description morphologique du pollen a été réalisée par microscopie électronique à balayage. Résultats. Les miels de jujubier appartiennent aux classes II et III de Maurizio, ils ne renferment aucun indicateur de miellat. Cinquante-quatre taxons de pollen appartenant à 35 familles ont été identifiés. Le nombre de types polliniques par échantillon varie de 16 à 37. Tous les miels analysés ont une dominance de pollen de jujubier supérieure à 46 %, avec un pourcentage moyen de 65,2 % ± 13,3. Le pollen de Peganum harmala L. est omniprésent dans les miels. La combinaison en pollen de P. harmala, Retam raetam, des genres Euphorbia et Brassica forme, ainsi que certaines espèces d’astéracées des genres Centaurea, Echinops, Calendula et Carduus type, pourrait caractériser les miels de jujubier d'Algérie. Le pollen de Z. lotus est tricolporé avec de longs sillons méridiens, isopolaire à symétrie radiale, triangulaire en vue polaire, majoritairement de taille médium et de forme prolate. L’ornementation de l’exine est de type rugulé. Conclusions. Cette étude permet de construire une base de données pollinique référentielle des miels de jujubier d’Algérie.
