### Chemical Compositions of the Most Active Essential Oils  
The composition analysis of six EOs has been performed by GC \(\times\) GC mass spectrometry. A quantitative analysis has been carried out by peak area normalization measurements without \begin{table}

Figure 4: Synergistic action of amphotericin B with cinnamon oil (upper disc 10 \(\mathrm{\SIUnitSymbolMicro g}\) of amphotericin B alone, bottom left 10 \(\mathrm{\SIUnitSymbolMicro u}\)L of cinnamon oil alone diluted 10 times with DMSO (dimethyl sulfoxide), bottom right AmB and EO in combination). DMSO alone does not show the inhibitory zone. correction factors as percentages of each component (Table 8). The highest diversity in chemical composition was marked for geranium oil, but the content of any particular component did not exceed 20%. The smallest number of components was seen for clove oil, with a predominance of eugenol (68.24%). Some monoterpenes were common for most of the tested oils (camphene, cymene, myrcene, pinene, and terpinene). The most active cinnamon oil contained high concentration of cinnamaldehyde (42.79%), while lemon oil contained the highest amount of citral (53.85%). \begin{table}
