“…The TPC of our propolis (237.18 mg GAE/g sample) agreed with values obtained by Ahn et al (2004) in Korean propolis (85-283 mg GAE/g) and by Moreira et al(2008)in Portuguese propolis (151-329 mg GAE/g). However, the TPC of our propolis was higher than the values reported by Siripatrawan et al(2013) and Kumazawa et al(2004)in Thai propolis,22.8-77.5 mg GAE/g and 31.2 mg GAE/g, respectively, and Choi et al (2006) in Brazilian propolis (120 mg GAE/g). On the other hand, the TPC of Chinese propolis showed slightly higher values as ranged from 262 to 299 mg GAE/g .…”

“…Rutin, quercetin and naringenin were found to be the main phenolic compounds in propolis collected from Nan province, Thailand (Siripatrawan et al, 2013). Kumazawa et al (2004), who study the antioxidant activity of propolis of various geographic origins, found that propolis contained antioxidative compounds such as kaempferol and phenethylcaffeate showing the strong antioxidant activity. Phenols exhibits an excellent property of reducing spontaneous autoxidation of organic molecules (Ingold, 1961) through a general class of mechanism called chainbreaking.…”

Predictive mathematical modeling for EC50 calculation of antioxidant activity and antibacterial ability of Thai bee products

et al. 2017

Antioxidant activities of bee products from Thailand (honey, bee pollen and propolis) via the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulphonate)(ABTS) assays were determined. The prediction of the EC50 (the half maximal effective concentration) were studied using the logistic, sigmoidal, dose response, and asymmetric 5 parameters (5P) regression models. The antimicrobial ability was tested against Staphylococcus aureus (TISTR 517), Bacillus cereus (TISTR 687), and Escherichia coli(TISTR 1261). Propolis extract with higher total phenolic content (TPC) exhibited more effective antiradical action against the DPPH and ABTS, followed by bee pollen extract and honey. All four regression models could be used to estimate the EC50 of the bee products. However, the dose-respond and 5P provide the better EC50 prediction for the bee products than the others based on the comparability of their results to those of right-angled triangle method. Thai bee products had effective antimicrobial activities on each test microorganism. The antimicrobial potency of the bee products was ranged in the order: propolis> bee pollen >honey. Results revealed that antioxidant activity and antimicrobial ability of the bee products correlated with the TPC values.

“…Furthermore, a single sample could take an hour to be analyzed. As most of the active components in propolis are polar, HPLC-ESI-MS is substituting GC-MS to compare A. mellifera propolis from different regions [9,10] as well as its plant origins [12]. Although this method requires less sample preparation than GC, a typical chromatographic analysis takes between 30 min and 1 h, using around 1 mL min −1 of solvent throughout.…”

“…For the majority of Asian or African countries, however, the composition and plant origins of propolis samples are only recently being studied [9][10][11]. Both gas chromatography coupled to mass spectrometry (GC/MS) [7] and high performance liquid chromatography coupled to electrospray ionization mass spectrometry (HPLC/ESI-MS) have been used to compare A. mellifera propolis from different regions [9,10] as well as its plant origins [12].…”

a b s t r a c tChemical profiles of a representative set of 49 propolis ethanolic extracts collected worldwide (North and South America, Europe, Asia and Oceania) were obtained via easy ambient sonic-spray ionization mass spectrometry (EASI-MS). This simple and easily implemented fingerprinting technique analyses directly (without any pre-separation or sample manipulation) a tiny droplet of the ethanolic extract placed on a inert surface under ambient conditions. Data acquisition took about a minute per sample with no substantial sample carry-over. Extraction of propolis with ethanol by using an ultrasonic bath method gave EASI-MS data similar to the traditional maceration method, reducing total analysis time for the crude propolis resin from a week to just ca 1 h. Principal component analysis of the EASI-MS data is shown to group samples according to the plant sources of their resins, which characterizes their geographical origin.

“…A determinação de polifenois no extrato de própolis foi feita pelo método colorimétrico de Folin-Ciocalteau (KuMAZAWA et al, 2004). em tubos de ensaio, foram homogeneizados 0,5 ml da solução de própolis diluída em 1:10 com 0,5 ml do reagente de Folin-Ciocalteau e 0,5 ml de Na 2 Co 3 a 10%.…”
