Abstract
The biocatalytic activity of five species of Passiflora leaves (i.e. P. amethyst, P. incarnata, P. quadrangularis, P. edulis, P. cerulea) was tested in the reduction of the ketone “cocktail” (i.e. 5-hexen-2-one 1, acetophenone 2, cisbicyclo[ 3.2.0]hept-2-en-6-one 3 and 2-methylcyclohexanone 4) and in the oxidation of the corresponding alcohols “cocktail” (i.e. 5-hexen-2-ol 5, 1-phenylethanol 6, endo-bicyclo[3.2.0]hept-2-en-6-ol 7, exo-bicyclo[3.2.0] hept-2-en- 6-ol 8, trans-2-methylcyclohexanol 9 and cis-2-methylcyclohexanol 10). P. amethyst and P. incarnata show the best activity in the reduction, while P. quadrangularis affords low yield in reduction but gives appreciable results in oxidation towards a cocktail of model substrates. This simple screening permits to test the potential of parts of fresh plants that can be used as biocatalysts in more ecologically and economically promising transformationsI documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
