Characterization of Zygophyllum album L Monofloral Honey from El-Oued, Algeria

Abstract

Background: Honey is generally evaluated by physicochemical analysis of its constituents. The manipulation of honey and its possible adulteration is reflected in many of its physicochemical properties. Objective: In this study, samples of Zygophyllum album L honey produced in El-Oued, Algeria, were characterized based on their melissopalynology, physicochemical and antioxidant properties, also polyphenol content. Methods: The physicochemical parameters of honey, such as density, moisture content, pH, free acidity, electrical conductivity (EC), total sugar content, color intensity, water insoluble solids content, hydroxymethylfurfural (HMF), ash, specific rotation, were measured. A number of antioxidant tests were performed to determine the antioxidant properties of Zygophyllum album L honey samples. The polyphenol in the Zygophyllum album L honey was measured by spectrometric determination based on folin-ciocalteu’s method. The identification and quantification of phenolic compounds were carried out by RP-HPLC (high-performance liquid chromatography). Results: All honey samples contained monofloral (67.83-91.89%) pollen belonging to Zygophyllum album L. The results of physicochemical parameters of analyzed honeys were: pH 4.33, moisture 17.2%, free acidity 41.96 meq/kg, electrical conductivity 0.408 mS/cm, HMF 11.89 mg/kg, Ash 0.246 (%), specific rotation -8.21. The Zygophyllum album L honey was extra white amber. The total sugar content ranged from 81.5 to 83. Honey samples contain high levels of gallic acid (252.53±15.56 mg/kg honey), chlorogenic acid (124.71±10.09 mg/kg) and low amounts of total polyphenol (467.82±46,98 mg GAE/kg). Conclusion: Physicochemical parameters (total acidity, pH, moisture, dry matter, ash, and qualitative hydroxymethylfurfural) were within the approved limits established by International Honey Commission.

Botanical Origin, Pollen Profile, and Physicochemical Properties of Algerian Honey from Different Bioclimatic Areas

“…Some authors studied the characteristics of honey produced in Algeria and found differing results as to the pollen content [ 8 , 9 , 10 , 13 ], physicochemical attributes and pollen profile of samples from different areas [ 7 , 14 , 15 , 16 ], their botanical origin [ 9 , 11 , 17 , 18 , 19 ], antibacterial and antioxidant activity [ 20 ], or specific compounds such as sugars and phenolic or volatile compounds [ 21 , 22 ]. However, honey production in Algeria remains poorly studied.…”

Biochemical Profiling and Physicochemical and Biological Valorization of Iraqi Honey: A Comprehensive Analysis

“…The total antioxidant capacity of the honey samples was determined using the phosphomolybdenum technique with minor modifications, as reported by Mesbahi et al [88]. In brief, 0.2 mL samples of honey were combined with a 2 mL reagent solution (0.6 M sulfuric acid, 28 mM sodium phosphate, and 4 mM ammonium molybdate).…”

Chemical Analysis of the Main Metabolites of Three Spontaneous Plants From the Saharan Area (Algeria)

“…Essential oil extracted from aerial parts of Cotula cinerea analyzed by GC-MS showed that (E)-citral, limoneneepoxidecis-, thymol methyl ether, carvacrol, trans-carveol,carvone and trans-piperitol were the considerable compounds [12].Likewise,[10] noted the presence of 3-carène, thujone, santolinatriene and camphor from the oil obtained from a specimen collected in Oued Souf area.The chiral flavanones analysis isolated from methanol extract of cotula cinerae aerial parts by TLC methods showed the presence of three compounds: Hesperidin , Hesperitin and Eriodoctyol[3].The evaluation of antioxidant activity of Tetraena alba (L.f.) extracts showed that acid ascorbic have a considerable antioxidant effect[6]. Two phenolic compounds; Gallic acid and ascorbic acid were extracted from Tetraena alba (L.f.) floral honey, had a significatively antioxidant activity[24] [21]. reported the identification of three metabolites from whole plant of Caroxylonimbricatum(Forssk.…”
