Research: Bee Pollen is a Source of Antioxidants and Antimicrobials


Screening of Plant Pollen Sources, Polyphenolic Compounds, Fatty Acids and Antioxidant/Antimicrobial Activity from Bee Pollen

Molecules 2022, 27(1), 117

In this study, the botanical origin, total flavonoid and phenolic content, antioxidant activity, phenolic profile and fatty acid composition of mixed bee pollen loads collected in Bayburt, Turkey, were determined.

In addition to these assays, antibacterial activity of bee-collected pollen extract (BCPE) against a variety of food-borne pathogenic bacteria was determined in vitro. Pollen loads were classified into five botanical families based on their color: Asteraceae, Fabaceae, Campanulaceae, Cistaceae and Rosaceae.

Total flavonoid, total phenolic, CUPRAC and CERAC concentrations were 173.52 mg GAE/g, 79.21 mg QE/g, 85.59 mg Trolox/g and 118.13 mg Trolox/g, respectively. Twenty-three phenolic compounds were scanned in bee pollen extract by LC-MS/MS, with rutin being the most abundant. Cis-4,7,10,13,16,19 docosahexaenoic acid was the predominant fatty acid, followed by cis-11-eicosenoic acid, palmitic acid, and alfa linolenic acid.

In addition, the agar well diffusion (AWD) and micro-broth dilution methods were used to determine of the antibacterial activity of the BCPE sample. MIC values were observed to vary between 2.5–5 mg/mL for Gram-positive bacteria and 5–10 mg/mL for Gram-negative bacteria.

These findings indicate that bee pollen could be a potential source of antioxidants and antimicrobials.

Propolis and Honey Better Than Acyclovir for Treating Cold Sores and Genital Herpes


Effect of honey and propolis, compared to acyclovir, against Herpes Simplex Virus (HSV)-induced lesions: A systematic review and meta-analysis


J Ethnopharmacol. 2021 Dec 26;287:114939

Ethnopharmacological relevance: Apitherapy is a branch of traditional medicine that uses bee products to manage numerous diseases. In this context, the antiherpetic effect of these bee products has been demonstrated in some studies with some controversial results.

Aim of the study: Thus, we conducted a systematic review and meta-analysis to compare the effectiveness of honey and propolis with acyclovir, the reference drug, in the treatment of cold sores and genital herpes.

Materials and methods: The selection of eligible studies was conducted through the search in Pubmed/MEDLINE, Scopus, Cochrane Library, LILACS, and Electronic Scientific Library.

Results: The search yielded 147 articles, of which nine were considered eligible for analysis. The analysis of these studies showed that the healing property of propolis is superior to that obtained for acyclovir (95% CI: 2.70 to 8.25; p = 0.0001). Furthermore, honey also presented a better healing effect than acyclovir against Herpes simplex virus-induced wounds (95% CI: 3.58 to -0.19; p = 0.03), inducing complete re-epithelization of herpetic lesions after 8 days, while for acyclovir, the healing time average was 9 days. It also provoked a similar reduction of pain caused by herpetic compared to acyclovir (95% CI: 2.27 to -0.42; p = 0.18).

Conclusions: Overall, these results confirm the use of honey and propolis as potent antiherpetic agents.

Report on the Health Benefits of Bee Products in Boosting Immunity; Treating Cancer, Diabetes, High Cholesterol, High Blood Pressure, Allergies


Bee Products: An Emblematic Example of Underutilized Sources of Bioactive Compounds

J Agric Food Chem. 2022 Jan 2.

Beside honey, honeybees (Apis mellifera L.) are able to produce many byproducts, including bee pollen, propolis, bee bread, royal jelly, and beeswax. Even if the medicinal properties of these byproducts have been recognized for thousands of years by the ancient civilizations, in the modern era, they have a limited use, essentially as nutritional supplements or health products. However, these natural products are excellent sources of bioactive compounds, macro- and micronutrients, that, in a synergistic way, confer multiple biological activities to these byproducts, such as, for example, antimicrobial, antioxidant, and anti-inflammatory properties.

This work aims to update the chemical and phytochemical composition of bee pollen, propolis, bee bread, royal jelly, and beeswax and to summarize the main effects exerted by these byproducts on human health, from the anticancer and immune-modulatory activities to the antidiabetic, hypolipidemic, hypotensive, and anti-allergic properties.

Stingless Bee Propolis May Help Treat Cancer


Cytotoxicity effect of honey, bee pollen, and propolis from seven stingless bees in some cancer cell lines


Saudi J Biol Sci. 2021 Dec;28(12):7182-7189

Our effort to find new material for anti cancer from natural resources leads us to focus on stingless bee products such as honey, bee pollen, and propolis. The products were from seven stingless bees named Homotrigona fimbriata, Heterotrigona itama, Heterotrigona bakeri, Tetragonula sarawakensis, Tetragonula testaceitarsis, Tetragonula fuscobalteata, Tetragonula laeviceps. The stingless bee products were evaluated for their cytotoxicity effect on MCF-7, HeLa and Caco-2 cancer cell lines.

This is the first time to be reported that the honey, ethanol extracts of bee pollen and propolis of H. fimbriata displayed more potent cytotoxicity than other stingless bee products.

By chromatography and biological activity-guided fractionation, ethanol extract of propolis from H. fimbriata was fractionated and isolated its active compound named mangiferonic acid. Mangiferonic acid showed a cytotoxicity effect with IC50 values 96.76 µM in MCF-7, > 110.04 µM in HeLa, and > 110.04 µM in Caco-2, respectively.

These results exhibited the potential of ethanol extracts from propolis of H. fimbriata to be further developed for drug and experiments to verify the function are essential.

Moroccan Propolis May Help Treat Diabetes

Beneficial Effect of Saharan Propolis on Glucose Metabolism in Streptozotocin-induced Diabetic Rats


Cardiovasc Hematol Disord Drug Targets. 2021 Nov 18

Aims: The aim of the study was to evaluate the antihyperglycemic activity of propolis from Saharan region of Morocco.

Background: Propolis is known from ancient times for its beneficial action on health.

Objective: The study aimed to evaluate the effect of Moroccan propolis aqueous extract from the desert region on glycemia and lipid metabolism.

Methods: The antihyperglycemic and antidyslipidemic activities of Moroccan propolis aqueous extract were evaluated in streptozotocin-induced diabetic rats. Glycemia was monitored during acute (6h) and subchronic treatments. Histopathological analysis of the liver and the serum lipid profile was also evaluated in addition to the glucose tolerance.

Results: This work demonstrated that the aqueous extract of Moroccan propolis exhibited a significant antihyperglycemic effect in diabetic rats. Histopathological data demonstrated that propolis acts positively on the liver of diabetic rats. In addition, the preliminary phytochemical screening revealed that Moroccan propolis contains several phytochemicals. Finally, Moroccan propolis had a potent antioxidant activity which may be due to the richness in polyphenols content (90.91 mg EAG/1 g of extract).

Conclusion: The present study shows that Moroccan propolis from the hot desert region possesses a potent antihyperglycemic effect.

Egypt Study: Propolis Bandage Used to Treat Burn Wounds


Deacetylated cellulose acetate nanofibrous dressing loaded with chitosan/propolis nanoparticles for the effective treatment of burn wounds


Int J Biol Macromol. 2021 Nov 10;S0141-8130(21)02432-6

Every year, about 1 out of 9 get burnt in Egypt, with a mortality rate of 37%, and they suffer from physical disfigurement and trauma. For the treatment of second-degree burns, we aim to make a smart bandage provided with control of drug release (chitosan nanoparticles) to enhance the healing process. This bandage is composed of natural materials such as cellulose acetate (CA), chitosan, propolis as the loaded drug (bee resin). Cellulose acetate nanofibers were deacetylated by NaOH after optimizing the reaction time and the concentration of NaOH solution, and the product was confirmed with FTIR analysis. Chitosan/propolis nanoparticles were prepared by ion gelation method with size ranging from 100 to 200 nm and a polydispersity index of 0.3. Chitosan/propolis nanoparticles were preloaded in the CA solution to ensure homogeneity. Loaded deacetylated cellulose nanofibers have shown the greatest hydrophobicity measured by contact angle. Cytotoxicity of propolis and chitosan/propolis nanoparticles were tested and the experimental IC50 value was about 137.5 and 116.0 μg/mL, respectively, with p-value ≤0.001. In addition, chitosan/propolis nanoparticles loaded into cellulose nanofibers showed a cell viability of 89.46%. In-vivo experiments showed that after 21 days of treatment with the loaded nanofibers repairing of epithelial cells, hair follicles and sebaceous glands in the skin of the burn wound were found in a mice model.

Why Propolis Might Be the Next Big Bee Byproduct


VOGUE

...Over the past few years, the benefits of propolis have slowly become more well-known, perhaps linked to the recent boom of designer honey. Manuka honey, which is thought to have antibacterial properties, can sell for up to $1,780. Propolis has admittedly experienced a much tamer ascent. When Stein searched for propolis products upon her return from Italy, the results were grim. “We were a little late to the party in North America,” says Stein. “I went back to finish up college in Canada where I’m from, and I couldn’t find these products. I found honey and manuka honey everywhere, but I couldn’t find propolis.” Stein started going to local beekeeping meetups and began making her own propolis mash-ups, using them herself or giving them to friends...

Yogurt, Propolis, Cinnamon Product Studied to Help Reduce Risk of Severe Viral Infections, Including COVID-19


Preparation and evaluation of novel functional fermented dairy products containing propolis and cinnamon


J Food Sci Technol. 2021 Oct 3;1-10

Novel functional food products might be an easy accessible and eligible approach to help reduce the risk of severe viral infections including SARS-CoV-2. Hence a product containing probiotics, propolis and cinnamon was developed and interferences of the ingredients were characterized.

Yogurts were prepared using starter cultures with propolis (0.03%) and cinnamon in various concentrations (0.3%, 1%, and 2.5%). Bifidobacterium animalis ssp. lactis, Lactobacillus acidophilus, Streptococcus thermophilus, and Lactobacillus delbrueckii subsp. bulgaricus were used as microorganisms for yogurt production. Chemical analysis revealed a decline of fat matter in the presence of propolis and/or cinnamon.

Propolis had statistically significant suppressive effects on Bifidobacterium animalis ssp. lactis as well as on Lactobacillus delbrueckii subsp. bulgaricus numbers (p < 0.05). These effects were diminished in the presence of increasing cinnamon concentrations. For Lactobacillus acidophilus a statistically significant reducing effect on the number of colonies was observed in all products investigated. Nevertheless all samples met the standard of recommended level of ≥ 106 viable cells/g of a product.

Propolis showed an inverse effect on Streptococcus thermophilus by increasing its colony numbers in yogurts. The probiotic yogurt samples containing propolis (0.03%) and cinnamon (2.5%) gained the highest number of points in the sensory evaluation compared to control.

Thyme Honey, Olive Oil Combine to Protect Against Diabetes Complications


The Synergistic Beneficial Effect of Thyme Honey and Olive Oil against Diabetes and Its Complications Induced by Alloxan in Wistar Rats

Evid Based Complement Alternat Med. 2021 Sep 20;2021:9949056

Diabetes is a metabolic disorder characterized by a chronic increase in blood glucose. Owing to the limitations observed with antidiabetics in modern medicine, medicinal plants and bee products are known as good matrices for the search for new antidiabetic molecules. 

The present study focused on the evaluation of the hypoglycemic and the protective properties of two natural products widely used in complementary and alternative medicine (thyme honey and olive oil). To achieve this, the study was carried out on Wistar rats rendered diabetic by the injection of a single dose of alloxan monohydrate (65 mg/kg body weight (BW)). 

First, the physicochemical characterization and the phytochemical analysis of thyme honey and olive oil were carried out, and then in vivo study was conducted on 42 Wistar rats divided into seven groups: three groups were normal, one group was untreated diabetic, and three groups were diabetic rats treated with thyme honey (2 g/kg BW) or olive oil (10 mL/kg BW) or their combination ((1 g/kg BW of thyme honey) and (5 mL/kg BW of olive oil)). During the experiment, the glycemia was measured regularly every 10 days. 

After 30 days of treatment, the rats were sacrificed. The serum and urine were analyzed to determine hepatic enzymes levels (AST, ALT, ALP, and LDH), lipidic profile (total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein), and kidney parameters (urea, uric acid, creatinine, total protein, sodium, potassium, and chloride). The liver, pancreas, and kidneys were analyzed to evaluate their histological changes and to determine their enzymatic antioxidant content (catalase, GSH, and GPx) and the levels of MDA. 

The results obtained showed that thyme honey or olive oil, and especially their combination, improved significantly the blood glucose levels and they protect against metabolic changes and the complications induced by diabetes.

Bee Venom Helps Treat Diabetic Heart Dysfunction


Bee venom ameliorates cardiac dysfunction in diabetic hyperlipidemic rats


Exp Biol Med (Maywood). 2021 Sep 22;15353702211045924

High levels of blood glucose and lipids are well-known risk factors for heart diseases. Bee venom is a natural product that has a potent hypoglycemic, hypolipidemic, anti-inflammatory, and antioxidant effects.

The current study aimed to determine the bee venom effects on cardiac dysfunction compared to combined therapy of metformin and atorvastatin in diabetic hyperlipidemic rats. The median lethal dose of bee venom was estimated, and then 50 adult male albino rats were categorized into five groups. One group was fed a standard diet and served as a negative control, while the other groups were given nicotinamide and streptozotocin injections to induce type 2 diabetes.

After confirming diabetes, the rats were fed a high-fat diet for four weeks. The four groups were divided as follows: one group served as a positive control, whereas the other three groups were treated with bee venom (0.5 mg/kg), bee venom (1.23 mg/kg), and combined therapy of metformin (60 mg/kg) and atorvastatin (10 mg/kg), respectively, for four weeks.

Upon termination of the experiment, blood samples and heart tissue were obtained. Administration of bee venom using both doses (0.5 and 1.23 mg/kg) and combined therapy of metformin and atorvastatin revealed a significant decrease in the concentrations of glucose, total cholesterol, triacylglycerol, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, troponin I, creatine kinase, and lactate dehydrogenase activities.

Moreover, a significant decrease had been detedcted in malondialdehyde, nuclear factor-kappa-β levels, and relative mRNA expression of vascular cell adhesion molecule-1 and galectin-3 in heart tissue compared to the positive control (P < 0.0001). Furthermore, there was a significant increase in bodyweight levels of insulin, high-density lipoprotein cholesterol, and total antioxidant capacity in heart tissue compared to the positive control (P < 0.0001).

The results indicate that bee venom can ameliorate cardiac dysfunction through attenuating oxidative stress and downregulating the NF-κβ signaling pathway.

Honey and Propolis Protect Liver and Kidneys from Damage


Protective Effect of Honey and Propolis against Gentamicin-Induced Oxidative Stress and Hepatorenal Damages


Oxid Med Cell Longev. 2021 Sep 2;2021:9719906

Bee 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 (120 mg/kg BW/day, i.p.) or normal saline (1 ml/kg BW/day, i.p.) for 10 consecutive days.

Honey (2 g/kg BW), propolis (100 mg/kg BW), or their combination were given daily by gavage to normal and gentamicin groups. Honey and propolis samples were evaluated for their phytochemical composition and antioxidant capacity. The in vitro investigations showed that the evaluated samples especially propolis extract have high antioxidant power associated with the presence of several phenolic compounds such as flavonoids, flavan-3-ols, hydroxybenzoic acids, hydroxycinnamic acids, and stilbenes, while honey contains only hydroxybenzoic acids and hydroxycinnamic acids.

It was also shown that simultaneous treatment with honey or propolis extract alone or in association prevented changes caused by gentamicin administration and improved hepatic and renal functions. Changes caused by gentamicin administration, observed by in vivo experiments, include significant elevation of uric acid, urea, creatinine, and hepatic enzyme levels (ALT, AST, and ALP) and kidney biochemical changes (an increase of urea, uric acid, and creatinine and a decrease of albumin and total protein) as well as remarkable changes of renal and liver oxidative stress markers (CAT, GPx, and GSH) and elevation of MDA levels.

Overall, it can be concluded that honey and propolis might be useful in the management of liver and renal diseases induced by xenobiotics.
