Effect of Aqueous and Alcoholic Bee Pollen Extracts on Monoamine Oxidase Activity

Abstract

Many researches have focused on the health and therapeutics properties and behaviour of phytochemical products, that including bee products. Bee pollen comprises on very large compounds such as flavonoids, phenolic acids and terpenoids, which have inhibiting effect on some enzymes. Monoamine oxidase (MAO) was an important metabolic enzyme. The aims of this study was to evaluation the effects of aqueous and ethanolic extracts of bee pollen on MAO and activities in human sera. The identification of extracts constituents was carried out by GC-Ms analysis technique. The results of the present study manifested the effectiveness of these two extracts which have an inhibitory effects on MAO. Different extracts and volumes have been used in this study which shows the inhibition percentage at maximum level equal to (79, 57) % in MAO and (57.33) % in ethanolic and aqueous extracts respectively. The recorded Km values in ethanolic extract were higher than Km in the aqueous extract, whereas the recorded Vmax values in aqueous extract were higher than Vmax in ethanolic extract. On the other hand, GC-Ms analysis of bee pollen extracts revealed the existence of 40 compounds.

Green synthesis and characterization of Zirconium Oxide with antimicrobial activities

“…Nanoparticles have shown promise as effective antimicrobial agents due to their unique size-dependent properties and high surface area. Therefore, the investigation of the antimicrobial properties of ZrO 2 NPs synthesized using eco-friendly methods is of particular significance [14][15][16]. The results of our study reveal potent antibacterial and antifungal activities of the green-synthesized ZrO 2 NPs.…”

“…Characterization of the synthesized ZrO 2 NPs is of paramount importance to assess their quality, structure, and chemical composition. In this study, a comprehensive set of analytical techniques, including UV-Vis spectroscopy, X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR), was employed to characterize the ZrO 2 NPs [14][15][16]. These techniques provide valuable insights into the physical and chemical properties of the nanoparticles, confirming the successful synthesis of crystalline ZrO 2 NPs with a narrow size distribution.…”

Optimization of microwave extraction of biocompounds from black pepper using meat quality assessment

“…Also, functional compounds can be isolated for medicinal or therapeutic uses. The quantity of compounds harvested using this methodology exceeds the 55 compounds found in Piper nigrum by Mohammed et al (2016), attesting to the efficiency of extraction method employed.…”
