In the study, two types of propolis extracts were used which were prepared in different solvent environment (50 % ethyl alcohol – 50 % pure water; 47 % propylene glycol – 53 % pure water).
Although healthcare professionals need to change their masks periodically, it is known that they do not have the opportunity to change their masks as often as necessary during emergencies [2].
As it is given, the solvent of Extract 1 (E-1) is a mixture of ethyl alcohol and pure water, whereas propylene glycol and pure water were used as the solvent in Extract 2 (E-2).
E-1 50 % ethyl alcohol 50 % pure water 24 hours 40°C E-2 47 % propylene glycol 53 % pure water 24 hours 30°C Table 3.
HPLC-DAD analyses showed that raw propolis extracted in ethyl alcohol-pure water and propylene glycol-pure water media have different phenolic components which lead to difference in antibacterial activity.
