Determining Quality in Propolis Samples
Bee propolis, the glue-like substance honeybees manufacture from plant resins, possesses anti-microbial and anti-viral properties as well as being anti-inflammatory and hepatoprotective with biological activities to repel tumors and stimulate the immune system. It is a popular remedy used in alternative and complimentary medicine, such as apitherapy, is a constituent of "biocosmetics," and is c...
متن کاملDetermination of the Mineral Composition and Toxic Element Contents of Propolis by Near Infrared Spectroscopy
The potential of near infrared spectroscopy (NIR) with remote reflectance fiber-optic probes for determining the mineral composition of propolis was evaluated. This technology allows direct measurements without prior sample treatment. Ninety one samples of propolis were collected in Chile (Bio-Bio region) and Spain (Castilla-León and Galicia regions). The minerals measured were aluminum, calciu...
متن کاملPhytochemical analysis and biological evaluation of selected African propolis samples from Cameroon and Congo.
The objective of this study was the chemical analysis of four selected samples of African propolis (Congo and Cameroon) and their biological evaluation. Twenty-one secondary metabolites belonging to four different chemical groups were isolated from the 70% ethanolic extracts of propolis and their structures were elucidated on the basis of spectral evidence. Three triterpenes and two diprenyl-fl...
متن کاملSeasonal Variation, Chemical Composition and Antioxidant activity of Brazilian Propolis Samples
Total phenolic contents, antioxidant activity and chemical composition of propolis samples from three localities of Minas Gerais state (southeast Brazil) were determined. Total phenolic contents were determined by the Folin-Ciocalteau method, antioxidant activity was evaluated by DPPH, using BHT as reference, and chemical composition was analyzed by GC/MS. Propolis from Itapecerica and Paula Câ...
متن کاملDetermination of chemical composition of Turkish propolis.
The aim of the present work is to study the chemical composition of Turkish propolis. Propolis samples were collected from different regions of Turkey (Bursa, Erzurum-Askale, Gumushane-Sogutagil and Trabzon-Caglayan) in 1999. Ethanol extracts of propolis (EEP) were prepared for chemical analysis, using gas chromatograph coupled with mass spectrometry (GC-MS). Our findings show that propolis sam...
