Cyclic voltammetry and UV/Vis spectroscopy in combination with multivariate data analysis for the assessment of authenticity of poplar type propolis

摘要: Propolis, as a beneficial natural product, has found application in the food and pharmaceutical industries preservative, active packaging material well main component of propolis containing products. Quality control thus gained importance. We used simple, fast, low-cost techniques such UV/Vis spectrophotometry cyclic voltammetry applied combination with principal analysis to confirm presence two botanical sub-types propolis. Cyclic voltammetry, green, sensitive, convenient technique suitable for investigation chemical profile, together multivariate chemometrics technique, was first time characterization classification spectroscopy aspects, absorption at certain wavelength quantitative determination analytes, i.e. quality parameters, spectral profiles, confirmation existence botanically different pop...
