The paper reports the chemical composition and biological activity of the essential oils obtained from the leaves of two cultivars of Florence fennel cropped under three different fertilization treatments (Control not fertilized; Mineral Fertilization; Compost from Municipal Solid Wastes). All the oils were characterized by high anethole concentration and some showed also a good percentage of limonene. The antimicrobial activity expressed by assays on the examined oils indicates an appreciable effect generally higher on Gram-positive bacteria. The various samples of Florence fennel analyzed did not show any results with FRAP test. The DPPH test showed a weak capacity of the samples to catch the free radical from the solution attributable to their content in anethole.

Abstract
The paper reports the chemical composition and biological activity of the essential oils obtained from the leaves of two cultivars of Florence fennel cropped under three different fertilization treatments (Control not fertilized; Mineral Fertilization; Compost from Municipal Solid Wastes). All the oils were characterized by high anethole concentration and some showed also a good percentage of limonene. The antimicrobial activity expressed by assays on the examined oils indicates an appreciable effect generally higher on Gram-positive bacteria. The various samples of Florence fennel analyzed did not show any results with FRAP test. The DPPH test showed a weak capacity of the samples to catch the free radical from the solution attributable to their content in anethole.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
