“…For nickel, the sample from Taounate (S3) had the lowest quantity (0.13 mg/kg) and the sample from Boulemane (S1) had the highest concentration (2.10 mg/kg). The amount of Zn found in our studied samples is lower than that showed in 25 Brazilian propolis samples (Souza, Zaluski, Veiga, & Orsi, 2016). Micro-elements are known beneficial for our organism; in fact, they act in synergy with enzymes in the catalysis of several chemical reactions.…”

In 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 some biological activities (antioxidant, and α-glucosidase and α-amylase inhibitory activities) were determined. The analyzed physicochemical parameters showed the following values: moisture (3.3-5.2%), pH (4.1-5.5), soluble substance (66.1-75.4%), insoluble substance (23.8-33.7%), ashes (1.6-2.3%), conductivity (1.5-2.5 mS/cm), organic matter (97.70-98.4%), wax (19.7-51.5%), resin (46.8-75.2%), balsam (1.5-3.1%), total carbohydrates (1.5-2.0 mg Glceq/g), and total proteins (1.7-6.2 g/100 g). Calcium, sodium, potassium, and magnesium were the most predominant minerals present in propolis samples. The phytochemical composition indicated the presence of phenolic acids, flavonoids and stilbens compounds described as having a high antioxidant capacity and potential α-amylase (IC 50 = 195.09-963.79 μg/mL) and α-glucosidase (IC 50 = 90.99-876.24 μg/mL) inhibitory activities.Moreover, FTIR spectra showed that the samples are structurally different between them, validating the results of the physicochemical analysis. The outcome of this study provides relevant information about Moroccan propolis composition and quality standards.

The last few years numerous publications have been published about the properties and plant origin of propolis, the glue-like resinous product collected by honeybees. Although, only one scientific experiment has been previously conducted on propolis collection techniques by honey bees, making the relative literature extremely limited in this area. The present study scopes to evaluate the effect of the trap types on the quantity of propolis collected by honeybees. For this reason, at two different locations, five different types of propolis collection traps, applied on Langstroth bee hives, were tested: 3 hand-cut screens plus one commercial screen on the top bars, as well as a lateral side modification of a Langstroth hive. Results show that two hand-cut screens with smaller openings (1 × 1 mm and 2 × 2 mm) as well as the commercial screen collected significantly more propolis than the others (F 4,41 = 43.21, P < 0.0001). Furthermore, the two hand-cut screens filled faster with propolis.

“…Dereplication studies using HPLC-DAD-ESI-MS/MS identified the presence of pyrrolizidine alkaloids 7-(3-methoxy-2-methylbutyryl)-9-echimidinylretronecine and caffeoylquinic acid-O-arabinoside [42], but studies that report the isolation and identification of alkaloids from propolis using MS and NMR are rare. Trace elements such as Al, Ca, Fe, K, Mg, P, Zn, Cr, Ni, and Cu and possible toxic metals (As, Cd, and Pb) have also been reported [43][44][45].…”

The Strong Anti-Kinetoplastid Properties of Bee Propolis: Composition and Identification of the Active Agents and Their Biochemical Targets

et al. 2020

The kinetoplastids are protozoa characterized by the presence of a distinctive organelle, called the kinetoplast, which contains a large amount of DNA (kinetoplast DNA (kDNA)) inside their single mitochondrion. Kinetoplastids of medical and veterinary importance include Trypanosoma spp. (the causative agents of human and animal African Trypanosomiasis and of Chagas disease) and Leishmania spp. (the causative agents of the various forms of leishmaniasis). These neglected diseases affect millions of people across the globe, but drug treatment is hampered by the challenges of toxicity and drug resistance, among others. Propolis (a natural product made by bees) and compounds isolated from it are now being investigated as novel treatments of kinetoplastid infections. The anti-kinetoplastid efficacy of propolis is probably a consequence of its reported activity against kinetoplastid parasites of bees. This article presents a review of the reported anti-kinetoplastid potential of propolis, highlighting its anti-kinetoplastid activity in vitro and in vivo regardless of geographical origin. The mode of action of propolis depends on the organism it is acting on and includes growth inhibition, immunomodulation, macrophage activation, perturbation of the cell membrane architecture, phospholipid disturbances, and mitochondrial targets. This gives ample scope for further investigations toward the rational development of sustainable anti-kinetoplastid drugs.
