Unveiling the techno-functional and bioactive properties of bee pollen as an ad...
Hassan Laaroussi; Santos, Pedro Miguel Ferreira; Genisheva, Zlatina; Bakour, Meryem; Ousaaid, Driss; Asmae, El Ghouizi; Teixeira, J. A.; Lyoussi, BadiaaBee pollen is an imperative product for human use. Seven bee pollens were harvested from Morocco, and their chemical, biological and techno-functional properties were studied. All samples showed acceptable physicochemical and nutritional quality with a mean energy value of 239 kcal/100g. FTIR spectra confirmed the presence of major constituents like carbohydrates, lipids, proteins and polyphenols. Moreover, pol...
Exploring the palynological, chemical, and bioactive properties of non-studied ...
Bakour, Meryem; Laaroussi, Hassan; Santos, Pedro Miguel Ferreira; Genisheva, Zlatina Asenova; Ousaaid, Driss; Teixeira, J. A.; Lyoussi, BadiaaBee products are known for their beneficial properties widely used in complementary medicine. This study aims to unveil the physicochemical, nutritional value, and phenolic profile of bee pollen and honey collected from Boulemane–Morocco, and to evaluate their antioxidant and antihyperglycemic activity. The results indicate that Citrus aurantium pollen grains were the majority pollen in both samples. Bee pollen...
Physicochemical characteristics and antiproliferative and antioxidant activitie...
Elamine, Youssef; Lyoussi, Badiaa; Miguel, Maria G.; Anjos, Ofelia; Estevinho, Leticia; Alaiz, Manuel; Giron-Calle, Julio; Martin, Jesus; Vioque, JavierZantaz honey is a monofloral variety produced from the melliferous plant Bupleurum spinosum (Apiaceae), a shrub that grows mainly in the Atlas Moroccan Mountains. Determination of the polyphenol composition revealed that methyl syringate accounts for more than 50% of total polyphenols, which represents a very useful parameter for the characterization of this monofloral honey. Epicatechin, syringic acid and cate...
Protective effect of honey and propolis against gentamicin-induced oxidative st...
Hassan Laaroussi; Bakour, Meryem; Ousaaid, Driss; Santos, Pedro Miguel Ferreira; Genisheva, Zlatina; El Ghouizi, Asmae; Aboulghazi, AbderrazakBee products are a promising source of phenolic compounds with strong antioxidant activity. The present study was designed to explore the protective effect of honey, propolis, and their combination on gentamicin-induced oxidative stress and hepatorenal dysfunction. This study was conducted on male Wistar rats by intraperitoneal injections of gentamicin (120mg/kg BW/day, i.p.) or normal saline (1ml/kg BW/day, i....

Laaroussi, Hassan; Santos, Pedro Miguel Ferreira; Genisheva, Zlatina; Bakour, Meryem; Ousaaid, Driss; Teixeira, J. A.; Lyoussi, BadiaaIn the present study, seven propolis samples collected from different areas of Morocco were evaluated for various potential attributes. Physicochemical parameters (moisture, pH, soluble substance, insoluble substance, ash content, conductivity, organic matter, resin, balsams, total carbohydrates, total proteins and mineral content), structural characterization by FTIR, phenolic and flavonoid composition and som...

EL-GEUNDOUZ, Soukaina; Lyoussi, Badiaa; Miguel, Maria da GraçaRoyal jelly (RJ) is a secretion of the hypopharyngeal and mandibular glands of young Apis mellifera worker bees. It is privileged for the queen bee as exclusive nourishment for her entire life. This bee hive product was used in traditional and folk medicine for human health care. Recently, there have been several research studies on RJ highlighting their therapeutic properties. It was found that it exhibits a l...
Chemical characterization and biological properties of royal jelly samples from...
EL-GEUNDOUZ, Soukaina; Machado, Alexandra M.; AAZZA, Smail; Lyoussi, Badiaa; Miguel, Maria; Mateus, Maria; Figueiredo, A. CristinaRoyal jelly (RJ) is a bee product that has high nutritional value and is beneficial for the human health, earning importance as a functional food. Thus, the characterization of its main biological properties is with high importance. In this work, 6 RJ samples obtained in Morocco, Portugal, and Spain were evaluated in terms of total phenol and flavone/flavonol contents; total protein; 10-hydroxy-2-decenoic acid ...
Natural antioxidants in emulsions O/W
EL-GEUNDOUZ, Soukaina; Azza, S.; Dandlen, Susana Anahi; MAJDOUB, Nesrine; Lyoussi, Badiaa; Raposo, Sara; Gomes, Vera; Bankova, Vassya; Popova, MilenaThis study compared the capacity of propolis extract (PE) and thyme waste extract (TWE) to prevent the oxidation of oil in water (O/W) emulsion, as well as their impact on emulsion apparent viscosity (AV) in the presence of wheat germ and almond oils as lipid phase. For this, central composite design (CCD) and principal component analysis (PCA) were performed. Oxidation process was monitored by evaluating the f...
Effect of antioxidant-rich propolis and bee pollen extracts against D-glucose i...
Hassan Laaroussi; Bakour, Meryem; Ousaaid, Driss; Aboulghazi, Abderrazak; Ferreira-Santos, P.; Genisheva, Zlatina; Teixeira, J. A.; Lyoussi, BadiaaThe present study was designed to investigate the preventive effect of propolis, bee pollen and their combination on Type 2 diabetes induced by D-glucose in rats. The study was carried out by feeding daily two concentrations (100 and 200 mg/Kg BW) of propolis or bee pollen (or their combination to normal (non-diabetic) and diabetic rats for a period of 16 weeks. In vivo biochemical changes associated to diabete...
