THE INFLUENCE OF THE SPECIES' CULTIVATION SYSTEM AND THE HARVESTING STAGE ON SOME QUALITY ELEMENTS IN MENTHA SPP

Rezumat

This paper presents the results of a study conducted on the genus Mentha ssp (Menta piperita and Menta spicata) cultivated in two different periods and in two different systems. Fertilizations were applied to the crop and irrigation was performed as often as the plants needed. The essential oil content and its composition were determined as well as the fresh and dried harvest quantity. After drying, an analysis was carried out by gas chromatography-mass spectrometry (GC-MS) performed on an Agilent Technologies 7890A gas chromatograph, equipped with an HP-5 MS capillary column (30 m x 0.25 mm, film thickness 0.25 μm), connected in series with an Agilent Technologies 5975C mass spectrometer. The ionization method was electron beam bombardment at 70 eV (EIMS).
