BACKGROUND: Monosodium glutamate is commonly used in our foods and reported many physiological effects. Propolis is a natural product widely used in folk medicine due to its bioactive compounds. It is considered one of the richest sources of phenolic acids and flavonoids. METHODS: The phenolic acids and flavonoids content of Saudi Arabian propolis was determined by HPLC analysis. Three groups o...

Antioxidant activity, total phenolic, total flavonoid compounds and cytotoxicity to cancer cell lines of propolis extracts from two extraction methods were investigated in this study. Propolis was collected from Phayao province and extracted with 70% ethanol using maceration and sonication techniques. The antioxidant activity was evaluated by DPPH assay. Total phenolic and flavonoid compounds w...

BACKGROUND Increased nitric oxide (NO), neuronal inflammation and apoptosis have been proposed to be involved in excitotoxicity plays a part in many neurodegenerative diseases. To understand the neuro-protective effects of propolis, activities of Nitric oxide synthase (NOS) and caspase-3 along with NO and tumor necrosis factor-α (TNF-α) levels were studied in cerebral cortex (CC), cerebellum (C...

Propolis is a resinous substance collected from plants by bees. Its composition depends on the vegetation, the season, and the source area. It usually contains many chemical compounds such as polyphenols, steroids and amino acids. The hereditary spherocytosis (HS) is a type of anaemia characterized by microcytic and hyperchromic red cells, spherical in shape and without central pallor. Clinical...

Propolis is a chemically complex resinous bee product which has gained worldwide popularity as a means to improve health condition and prevent diseases. The main constituents of an aqueous extract of a sample of green propolis from Southeast Brazil were shown by high performance liquid chromatography/mass spectroscopy/mass spectroscopy to be mono- and di-O-caffeoylquinic acids; phenylpropanoids...

Pollen analysis, total phenols content and antioxidant activity were studied for the first time in Portuguese propolis samples from Bornes and Fundão regions. Total phenols content was determined by colorimetric assay and their amount was of 329 mg/g of GAE in Bornes sample and 151 mg/g of GAE in Fundão propolis. The antioxidant capacity of propolis extracts was assessed through the scavenging ...

INTRODUCTION A previous study showed the unique character of Nigerian red propolis from Rivers State, Nigeria (RSN), with regards to chemical composition and activity against Trypanosoma brucei in comparison with other African propolis. OBJECTIVE To carry out fractionation and biological testing of Nigerian propolis in order to isolate compounds with anti-trypanosomal activity. To compare the...

OBJECTIVE To evaluate the antimicrobial effect by measuring the minimum inhibitory concentration MIC and minimum bactericidal concentration MBC of propolis, BioPure MTAD, 5% sodium hypochlorite (NaOCl), and 2% chlorhexidine CHX on Enterococcus faecalis (E. faecalis) and Candida albicans (C. albicans) in vitro. METHODS This study was performed in the Faculty of Dentistry and Pharmacy at Erciye...

INTRODUCTION Warfarin is commonly used to avoid thromboembolism, predominantly for cardiovascular pathologies. However, the consumption of several herbal products is not permitted during its use due to the associated interactions. Propolis is a popular phytotherapy product made by honey bees. The use of propolis has been dramatically increasing in recent times. AIM To evaluate the possible in...

The aim of this study was to investigate and assess the effects of propolis flavonoids liposome imposed on the immune system by comparing it to propolis flavonoids and blank liposome. In vitro, the effects of the above drugs on macrophages were assessed by measuring the phagocytic function and cytokine production. In vivo, the immunological adjuvant activity of propolis flavonoids liposome was ...
