The melissopalynologic results revealed that Sample 1 and 2 are polyfloral, and others are unifloral. Total contents of phenolics (116.47-1711.13 mg GAE/100g) and flavonoids (1.46-27.25 mg CAE/100g) were analyzed, and the antioxidant activities measured by ferrous ion chelating activity (FICA) (71.32-93.35%), hydrogen peroxide scavenging activity (HPSA) (SC 50 : 217.8-1238.39 µg/mL), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging (SC 50 : 20.15-27.14 µg/mL), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity (SC 50 : 22.93-308.17 µg/mL) and ferric reducing antioxidant power (FRAP) (71.03-99.54%) differed notably. For comparison of the samples, butylated hydroxy anisol (BHA), rutin (RUT) and trolox (TRO) were used as standard antioxidant compounds. According to these results, samples showed more efficient antioxidant activity than TRO except for ABTS assay. Also, Sample 1 and 4 have higher FICA activity and Sample 2 and 3 demonstrated more FRAP activity than standards. Honey samples demonstrated an inhibitory effect on the growth of Staphylococcus aureus and Escherichia coli, according to agar diffusion assays and minimum inhibitory concentration (MIC) values.

The bioactive properties of propolis are dependent on its botanical origin. This study investigated the pollen composition, antioxidant activities, and the total phenol and total flavonoid content of a propolis sample from the Refahiye (Erzincan, Turkey) region. Melissopalynological analysis conducted according to the relevant literature revealed that the pollen profile of the sample primarily indicated the presence of the Fabaceae (38.4%), Asteraceae (20.2%), and Fagaceae (11.2%) families. The antioxidant ability of propolis extract was analyzed by the hydrogen peroxide scavenging activity (HPSA) (in terms of SC50), ferric reducing antioxidant power capacity (FRAP) (%), DPPH radical scavenging activity (in terms of SC50), metal-chelating activity (%), total phenol content (TPC), and total flavonoid content (TFC), which showed the following values: 11.72±0.04 µg/mL, 90.73% ± 0.24%, 18.34±0.08 µg/mL, 89.69% ± 0.12%, 10673.4±3.30 mg GAE/100 g of propolis sample (PS), and 170.65±1.12 mg QE/100 g of PS, respectively. These results were compared using butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and α-tocopherol (TOC) as standard antioxidant compounds. The high biological activity of propolis from the Refahiye region could be attributed to its rich pollen composition. These results indicate that propolis is an important source in terms of its antioxidant activities.

We examined the botanical origin, total phenolic/flavonoid content (TPC/TFC), antioxidant/antimicrobial activity, and element content of pollen samples collected from honeybees. This study also examined whether the elements contained in pollen, when consumed as food, posed a risk to human health. Area of study: Ten mixed pollen samples were randomly collected from honeybees in the apiaries of four different Turkish regions, which fall among the three phytogeographic regions of Türkiye. Material and methods: We evaluated total flavonoid (TFC) and phenolic (TPC) contents; antioxidant activities (radical scavenging activity, hydrogen peroxide scavenging activity - HPSA, ferric reducing antioxidant power - FRAP, and ferrous ion chelating activity - FICA), element concentrations and antimicrobial activity. Main results: According to the melissopalynological analysis, one sample was determined to be unifloral and nine samples were found to be multifloral. The values found ranged 271.42-601.85 mg GAE/100 g TPC, 23.53-34.50 mg CAE/100 g TFC, 22.19-23.78 μg/mL DPPH, 6.50-78.40 µg/mL ABTS, 20.43-150.94 μg/mL HPSA, 97.26-99.83% FRAP and 74.84-91.79% FICA. Rosmanic acid, p-coumaric acid, quercetin, apigenin, and naringin were identified in all samples, while catechin was detected only in S6 and S7. Element contents were found Mg > Fe > Mn > Zn > Cu > Se > Cr > Ni > Cd > Co. All the samples had high antibacterial activity against Bacillus cereus (MIC= 4.17-8.33 g/mL), and against Staphylococcus aureus (MIC= 8.33 g/mL), except S3 and S4. Research highlights: Different levels and combinations of these components are efficient in the antioxidant and antibacterial activity of pollen.

Cyclamen’in bazı türlerinin tuber özütlerinin biyolojik aktivitelerinden dolayı halk arasında kullanılması nedeniyle, türün tuber özütü GC-MS (Gaz Kromatografisi-Kütle Spektrometresi) cihazı ile analiz edilmiş ve kimyasal içeriğine görede değerlendirilmiştir. Tuber özütünün analizi sonucunda alkoller, alifatik asit ve esterleri, aromatik bileşikler, karboksilik asit ve esterleri, hidrokarbonlar, yağ asit ve esterleri ve şekerler gruplarına dahil bileşikler saptanmıştır. “2-hidroksi-6metil-3-nitro-piran-4-on” bileşiği % 17.31 ‘lik bir oranla en yüksek miktarda bulunmuştur. Bu sonuçlar Cyclamen pseud-ibericum tuberlerinin yeni kullanımı için bir basamak olabilir. Kimyasal içeriğin bilinmesi biyolojik aktivite testlerini de kolaylaştıracaktır. Bu çalışmanın anatomik ve kimyasal sonuçları ise özellikle farmokolo...

Materials and Methods: The chemical composition of the ethanolic extracts of honeybee products was determined via gas chromatography-mass spectrometry (GC-MS) analysis. Furthermore, their in vitro anticancer, antimicrobial, antioxidant activities, total phenolic content (TPC), and total flavonoid content (TFC) were evaluated. Anticancer activities were assessed using the MTT assay while the antimicrobial potential was studied using the microdilution method. The antioxidant activities were investigated using the 2,2’-diphenyl-1-picrylhydrazyl radical (DPPH), hydrogen peroxide scavenging activity (H2O2) and ferric reducing antioxidant power (FRAP). The TPC and TFC were evaluated via Folin-Ciocalteu’s and AlCl3 assays, respectively. Results: In the GC-MS analyses, 36 compounds were identified in the ethanol extract of pollen accounting for 92.73% of the t...

The aim of this study is to interpret botanic origin, and antioxidant activity of five honey samples from Bitlis region. All the samples were classified as multifloral. The total phenol content (TPC), total flavonoid content (TFC), hydrogen peroxide scavenging activity (HPSA), ferric reducing antioxidant power (FRAP), DPPH radical scavenging activity (DPPH), ferrous ions chelating activity (FICA), ABTS radical cation scavenging activity (ABTS) of honey samples were found between, 165.73-349.41 mg GAE/100 g, 1.26-4.08 mg CAE/100, 201.76-216.59 µg/mL, 52.46-71.2%, 256.41-419.29 µg/mL, 69.44-94%, and 20.06-20.59 µg/mL, respectively. These results were compared with Trolox (TRO), Routine (RUT) and Butylated Hydroxy Anisole (BHA) standard antioxidant components. The reported information gives increased nutrition characteristics to honey and support to the growing of beekeeping, supplying a choice to family income raise.

In this study, the total phenolic-flavonoid content and pollen composition of fifteen honey samples were investigated from Ordu in Turkey. According to melissopalynological (qualitative) analysis, eleven honey samples were unifloral (Castanea sativa (9); Rosaceae (1) and Onobrychis spp.(1)), while four samples were multifloral. The forty-two pollen types from the samples were identified. The melissopalynological (quantitative) analysis based on Maurizio’s Class demonstrated that one in Class II, three in Class III, one in Class IV and ten in Class V. Total phenolic and total flavonoid amunts in these honeys varied from 32.5-171.05 mg GAE (gallic acid equivalent)/100g, 1.65-38.75 mg CAE (catechin equivalent)/100g, respectively. According to this study the highest flavonoid levels obtained from Sample 9 (multifloral) and the highest phenolic contents...
