“…In comparison, Ethanol 70% was considered an inert solvent and didn't report any inhibitory effect on any of the microbial isolates under study. Also, according to the results presented in table (7), Egyptian honey exhibited a significant antimicrobial activity among other honey types against Gram-negative and Gram-positive bacterial isolates, while both Saudi and Turkish honey showed nearby activities. Indeed, S. aureus and Acinetobacter spp.…”

Background: COVID-19 patients are vulnerable to develop secondary microbial infections that are frequently multidrugresistant (MDR) and increase the severity of the disease and mortality risk, which has created an urgent need for the use of natural products as antimicrobial agents.Objective: This study aimed to evaluate and compare the polyphenol content of some honeybee products from different origins as well as their antimicrobial activity against some MDR secondary microbial infections in COVID-19 patients. Methods: During the winter of 2021, sixteen clinical microbial isolates were collected from sputum and chest swabs of COVID-19 patients from some hospitals in Cairo, Egypt, and their antimicrobial susceptibility testing was performed. The total phenolic content (TPC) and total flavonoid content (TFC) of eight honeybee products from different origins were evaluated, and their antimicrobial activity was determined by recording the inhibition zone diameter (IZD) and minimum inhibitory concentration (MIC). Results: According to results, Turkish propolis, Egyptian royal jelly sample1, and Egyptian honey contained the highest polyphenol content and consequently showed significant antimicrobial activity compared to other bee products under study. Turkish propolis contained elevated polyphenol contents (TPC= 322.33 mg Gallic acid (GAE)/100 g and TFC= 88.974 mg Quercetin (QUE)/100 g) and expressed its antimicrobial activity with IZD ranging 15.33-28.33 mm and MIC value of 0.105-7.5 mg/ml. Also, Egyptian royal jelly1 and Egyptian honey contained high polyphenol contents (TPC= 134.737 mg GAE/100 g and TFC= 78.162 mg QUE/100 g) and (TPC= 98.571 mg GAE/100 g and TFC= 44.487 mg QUE/100 g), respectively, and showed antimicrobial activity with IZD of 0.00-21.66 mm and 0.00-22.00 mm, respectively, as well as MIC values of 1.150-4.69% and 6.25-37.50%, respectively. Indeed, all honey and royal jelly samples showed no activity against Candida spp., while propolis exhibited good action against it. Conclusion: Honeybee products are promising natural products that possess unique antimicrobial activities that help to fight MDR secondary microbial infections in COVID-19 patients, in which their antimicrobial activity is largely affected by polyphenol contents and geographical origins.

Nowadays, in people’s perceptions, the return to roots in all aspects of life is an increasing temptation. This tendency has also been observed in the medical field, despite the availability of high-level medical services with many years of research, expertise, and trials. Equilibrium is found in the combination of the two tendencies through the inclusion of the scientific experience with the advantages and benefits provided by nature. It is well accepted that the nutritional and medicinal properties of honey are closely related to the botanical origin of the plants at the base of honey production. Despite this, people perceive honey as a natural and subsequently a simple product from a chemical point of view. In reality, honey is a very complex matrix containing more than 200 compounds having a high degree of compositional variability as function of its origin. Therefore, when discussing the nutritional and medicinal properties of honey, the importance of the geographical origin and its link to the honey’s composition, due to potential emerging contaminants such as Rare Earth Elements (REEs), should also be considered. This work offers a critical view on the use of honey as a natural superfood, in a direct relationship with its botanical and geographical origin.

Honey intake is advantageous to human health due to its antioxidant, anticancer, anti-inflammatory, and antimicrobial properties, all of which are attributed to the rich bioactive compound contents. Moreover, hepatoprotective, wound healing, and gastrointestinal protective properties have been documented. Honey’s nutritional value is significantly affected by its chemical composition, which varies depending on botanical and geographical origin. In particular, after Manuka honey, Sidr honey from the Ziziphus species is the most popular. The chemical compositions, physicochemical properties, bioactive compounds, and sensory characteristics of two Sidr honey samples from Egypt and Saudi Arabia were investigated in the current study. Moisture content, electrical conductivity (EC), pH, free acidity (FA), total acidity, lactone hydroxymethylfurfural (HMF) content, and diastase (α-amylase) activity were measured. By using high-performance liquid chromatography (HPLC), mass spectrometry (LC-MS/MS), nuclear magnetic resonance (1HNMR), and solid-phase micro-extraction (SPME) coupled with gas chromatography (GC-MS) analyses, the sugar profile, non-volatile, and volatile compounds were also identified. The physicochemical analysis revealed the following results for Sidr honey from Saudi Arabia and Egypt, respectively: a moisture content of 18.03 ± 0.05% and 19.03 ± 0.06%, EC values of 1.18 ± 0.05 and 1.16 ± 0.01 mS/cm, pH values of 4.87 ± 0.08 and 5.10 ± 0.01, FA of 37.50 ± 0.05 and 36.50 ± 0.05 meq/kg, total acidity of 41.06 ± 0.05 and 37.50 ± 0.05 meq/kg, lactone of 3.49 ± 0.005 and 1 ± 0.0 meq/kg, HMF of 20.92 ± 0.02 and 11.33 ± 0.01 mg/kg, and diastase of 59.97 ± 0.05 and 8.64 ± 0.06g/100 g. Honey from Saudi Arabia and Egypt displayed 22.51 ± 0.05 and 26.62 ± 0.16 % glucose, 40.33 ± 0.06 and 35.28 ± 0.01% fructose, 8.94 ± 0.17, and 8.87 ± 0.01% sucrose, and 8.22 ± 0.006 and 8.13 ± 0.01% maltose, respectively. According to the International Honey Commission (IHC) and GCC Standardization Organization (GSO) regulations, the levels of glucose, fructose, sucrose, and maltose were near the standard levels. Flavonoids, sugars, vitamins, and nitrogen contents were additionally measured using LC-MS/MS, whereas GC-MS was employed to identify aldehydes, ketones, phenols, acids, esters, anthraquinone, hydrocarbons, and nitrogenous compounds. The results of a study on the effect of honey’s geographic origin on its broad quality are summarized. As a result, knowing its optimal chemical and physical characteristics served as the criterion and indicator of the honey’s quality.
