Abstract :

Mentha pulegium and Eucalyptus camaldulensis are important plant species with applications in flavouring processed foods. Their essential oils were tested for antifungal activity to explore biocontrol ways vs. fungal rot of apples in storage. Extracts analyses by gas chromatography-mass spectrometry revealed M. pulegium dominated by pulegone and E. camaldulensis, by 1,8 cineole and �?± pinene. Oils antifungal activity was studied vs. Alternaria alternata and Penicillium expansum. Oil of M. pulegium is thrice most active than E. camaldulensis. Chemical components show synergism. Inhibition suggests food-preservation application. Classification algorithms are proposed based on information entropy and its production. Oils components are classified by numbers of C=C bonds, O atoms and cycles. Classification algorithms are based on information entropy. When applying procedures to moderate-size sets, excessive results appear compatible with data and suffer combinatorial explosion; however, after equipartition conjecture one obtains selection criterion resulting from classification between hierarchical trees. Information entropy permits classifying oils components and agrees with principal component analyses.
