Table 5 : Quantitative range of the chemical markers found in the dry propolis extract obtained
for the encapsulating systems A
(arabic gum and silicon dioxide, 1:1) and B (modified starch and
silicon dioxide, 1:1). Additionally, the percentage in relation of
the theoretical value of the markers is presented.
