Tions (relative concentrations of compounds in ) have been performed around the peak
Tions (relative concentrations of compounds in ) were performed on the peak locations of the compounds derived in the GC-MS total ion or essential ion chromatogram profiles. Typical response components were calculated for every single compound.Statistical analysisThe data set was statistically analyzed by cluster evaluation and principal component analysis (PCA) tactics using the SPSS (IBM-Statistical Package for the Social Sciences, version 21) computer software to assess the similarity and dissimilarity among the various propolis samples.PLOS A single | DOI:ten.1371/journal.pone.0128311 June 15,4 /GDNF Protein Gene ID Asphalt Elements in Propolis Created by Urban HoneybeesFig 2.

The presence and distribution IGF-I/IGF-1, Rat patterns of these compounds in propolis may be utilized to determine their sources. Accordingly, comparisons are possible in between recognized sources and observed organic compound mixtures within the propolis and asphalt samples.PLOS One | DOI:10.1371/journal.pone.0128311 June 15,six /Table 1.
