Application of metabolite profiling and antioxidant activity in assessing the quality of processed and unprocessed stingless bee’s propolis

Shelf Life of Saurida tumbil during Storage at Refrigeration Condition as affected by Gelatin-Based Edible Coatings Incorporated with propolis Extract

“…[1,2] The main components of propolis include aromatic acids, aromatic esters, volatile compounds, aromatic compounds, hydrocarbons, steroids, enzymes, flavonoids, acids, micro-and macronutrients, vitamins, and essential oils. [3,4] Propolis, as a natural product, is the major source of bioactive compounds including antimicrobial properties [1,5,6] and antioxidative properties [4,7,8] that, in the last few decades, has gained wide acceptance across numerous countries as a natural preservative enhancing health and preventing disease in food products. [9,10] There are three methods for processing of soaking crumbled propolis including ethanol, glycerol, and/or water.…”

HPTLC Profiling and Ftir Fingerprinting Coupled With Chemometric Analysis of Malaysian Stingless Bee Propolis

“…HPTLC chromatography was performed on HPTLC glass plate coated with silica gel 60 F254 (20 cm x 10 cm, Merck, Germany) followed method by Azemin et al, (2017) with slight modifications [23]. The methanolic propolis extract samples were weighed 30 mg and dissolved in 1 mL of methanol.…”

“…Additionally, this technique has been used for fingerprinting analysis of complex matrix of propolis [19,20,21,22]. For instance, Azemin et al, (2017) studied the quality of processed and unprocessed stingless bee propolis from Malaysia using HPTLC and had concluded the method of processing influenced the chemical profile of propolis [23]. However, only few studies have been reported on HPTLC profiling of Malaysian stingless bee propolis from different origins.…”

Antimicrobial Activity of Propolis Extract and Their Application as a Natural Preservative in Livestock Products: A Meta-Analysis

“…In recent decades, it has been widely accepted in many countries as a dietary supplement for promoting health and preventing disease. In general, propolis influences human health ( Azemin et al, 2018 ; Farooqui and Farooqui, 2012 ).…”

“…The health-promoting properties of propolis come from its chemical composition, including antimicrobial and antiviral ( Bankova et al., 2014 ; das Neves et al, 2016 ; Nolkemper et al, 2010 ), antioxidant properties ( Azemin et al, 2018 ; Mello and Hubinger, 2012 ; Sun et al, 2015 ), anticancer ( Markiewicz-Zukowska et al, 2013 ; Xuan et al, 2014 ), anti-inflammatory and cytostatic ( Corrêa et al, 2017 ; Kismet et al, 2017 ), immunostimulants ( Nassar et al, 2012 ), and anti-allergic ( Yasar et al, 2016 ). The rich bioactive components are useful in their application in various fields such as medicine and dentistry, pharmaceuticals, cosmetics, and the food industry.…”
