“…Moreover, most of the samples had green and yellow colors with negative a* and positive b*, respectively. Similar values in the three coordinates of the CIELab scale measured in honeys from Algeria were reported [6]. However, the lightness values (L) of the Tunisian and Estonian honeys ranged from 36.64 to 51.37 [39] and 65.3 to 90.4 for L [3], respectively, while positive values for a* and b* coordinates in both honey types were found [3,39].…”

“…The concentration of polyphenols varied between 19.7 and 464.1 mg GAE/100 g with a mean of 81.8 mg GAE/100 g (Table 3). These results in polyphenols are superior to other Algerian honeys (20 and 141 mg GAE/100 g) [6,10], Tunisian honeys (16 and 120 mg GAE/100 g) [39], and Estonian honeys (26 and 89 mg GAE/100 g) [3]. Regarding flavonoid content, the mean value obtained for all the samples was 3.1 mg QE/100 g, with maximum and minimum concentrations of 11.0 and 0.3 mg QE/100 g, respectively.…”

“…honey sample was collected in Skikda, belonging to the Mediterranean area. It is a rarely studied honey, which in palynological terms has barely been considered [6]. The reason is probably due to the low representation of the pollen grain in the pollen spectrum and the presence of others in a higher amount, which may hide the contribution of this plant to honey production.…”

“…Unifloral honey contains predominantly nectar from a single species and polyfloral honey is produced from the nectar of several plant species, but with none of them being prevalent. However, the success of the identification of geographical and botanical origin of the honey is due to the combination of melissopalynological analysis and physicochemical parameters [4][5][6][7][8]. Until now, some unifloral honeys from Algeria were discriminated based on their pollen profile and physicochemical properties: Hedysarum coronarium, Euphorbia bupleuroides, Citrus, Retama sphaerocarpa, Atractylis, Eruca sativa, Eucalyptus, Brassica, Foeniculum, Tamarix, Asteraceae, Capparis, Arbutus and Ziziphus lotus [5][6][7][8][9][10][11][12][13].…”

Honeys from different regions of Algeria were analyzed to determine their pollen characteristics and physicochemical properties (humidity, pH, electrical conductivity, diastase content, color, phenols, flavonoids and antioxidant activity). The antioxidant activity was investigated using the free radical scavenging and Ferric reducing/antioxidant power assays. The melissopalynological analysis revealed 129 pollen types from 53 botanical families. The pollen types found as dominant were Coriandrum, Bupleurum, Brassica napus type, Hedysarum coronarium, Ceratonia siliqua, Eucalyptus, Peganum harmala, Ziziphus lotus and Tamarix. Principal component analysis and cluster analysis were used to analyze significant relationships between the physicochemical variables and the botanical origin of the honeys and establish groupings based on the similarities of their physicochemical and antioxidant properties. The results showed that Ceratonia siliqua, Eucalyptus, Arbutus and honeydew honeys had a higher antioxidant contribution and higher phenolic and flavonoid contents than the rest of the honeys. In addition, the contributions of Mediterranean vegetation such as Myrtus and Phyllirea angustifolia were significant in this honey group. This paper demonstrates the diverse botanical variability for honey production in Algeria. However, there is a gap in its characterization based on its botanical origin. Therefore, these studies contribute positively to the needs of the beekeeping sector and the commercial valorization of the country’s honey.

There is a demand from the scientific, beekeeping and consumer sectors to characterize honey based on its botanical origin, as it provides unique and distinctive properties. Nevertheless, existing studies on the physicochemical properties and the sensorial profile of honey in relation to botanical origin remain insufficient. This study aimed to understand the relationships between sensory profile and various chemical compounds (minerals, sugars, water content and volatiles) of three monofloral honeys (Atractylis serratuloides, Retama sphaerocarpa and Eruca sativa) produced in Algeria using principal component analysis. Crystallization was detected as a distinctive attribute of Eruca and Atractylis honey. A candy aroma and odor with floral nuances, light color, crystallized state and the volatile compounds Alpha-Bisabolol and Beta-eudesmol characterized the Atractylis honey. Eruca honeys were distinguished by an animal and degraded odor, bitter taste, light color and the presence of Dimethyl trisulfide and Dimethyl tetrasulfide. Finally, a vegetal aroma, some saltiness and sourness, dark amber color, lower sugar content, higher K content and Lilac aldehyde and Lilac aldehyde D characterized Retama honeys.

Cyperus conglomeratus has been utilized in traditional medicine as an emollient, diuretic, analgesic, anthelmintic, and for other diseases. Furthermore, several biological activities have been reported for the plant extract and the isolated metabolites. The chromatographic investigation of an ethyl acetate extract of the aerial parts led to the isolation of three aurone derivatives (1–3) from the plant for the first time. Their structures were identified as aureusidin (1), aureusidin-4-methyl ether (2), and 5-methyl aureusidin (3) using 1D and 2D NMR techniques, along with mass spectrometry. The compounds were tested for their inhibitory activities against enzymes vital in metabolic diseases, especially diabetes, such as α-amylase, α-glucosidase, and glycogen phosphorylase. The results were expressed as percentage inhibition. The inhibitory activity of aurones against the tested enzymes was also analyzed by computational docking studies to provide a rational explanation for the observed results. The tested compounds formed stable interactions in terms of hydrogen bonding and hydrophobic interaction with the active site residues of the tested enzymes, and the results are in agreement with those of the in vitro antidiabetic activity. The compounds were also evaluated for their ability to support the growth and viability of beneficial bacteria in terms of prebiotic activities using two species, Lacticaseibacillus paracasei and Lacticaseibacillus rhamnosus, through the determination of prebiotic activity scores (Pscore). The findings of this study showed that C. conglomeratus is a potential natural source of bioactive agents. There is, however, a need for in vivo testing to evaluate this plant’s efficacy for developing new drug entities in the future.
