Abstract

Red propolis is a resinous product that bees produce and is typical of the northeastern states of Brazil. The compositiion of propolis composition varies widely depending on its botanical and geographical origin and on the bee involved in the collecting process. Different types of red propolis have been identified: group A presented the marker ion m/z 601.35 (C38H49O6) and includes samples from the states of Alagoas and Paraíba. Group B includes samples from Sergipe and Cuba, and presented a similar composition profile to the one of Dalbergia ecastophyllum, which has been identified as one of the botanical sources of red propolis. The ion markers of this group are m/z 255.06 (C15H11O4) - pinocembrin, m/z 267.06 (C16H11O4) - formononecin, m/z 271.06 (C15H11O5), m/z 271.10 (C16H11O4), m/z 283.06 (C16H11O5) - biochanin A, and m/z 301.07 (C16H13O6). The identification of the composition and the chemical structure of the ion markers by different techniques such as mass spectrometry and nuclear magnetic ressonance is important to standardize red propolis, since it has promising therapeutical properties and is a substance of interest for the food and pharmaceutical industry. It has antimicrobial, antioxidant, cytotoxic, analgesic, anti-inflammatory and liver protective activity, among others. Thus, not only the activity of propolis samples should be evaluated, but it is also indicated to evaluate the individual activity of the substances present in the sample to identify the bioactive compounds.
