STUDIES CONCERNING THE HISTO-ANATOMY AND BIOCHEMISTRY OF MENTHA LONGIFOLIA (L.) HUDS. DURING VEGETATIVE PHENOPHASE

The article analyzed the histo-anatomy of the vegetative organs of species Mentha longifolia (L.) Huds collected from Negre ti (Vaslui). On the surface of the vegetative organs was identified the presence of tectorial and secretory hairs. Volatile oil was extracted from the aerial parts of the plant using a Clevenger device, and with a GC-MS (Gas Chromatography coupled with mass spectrometry) there were identified the chemical compounds. It was recorded the presence of 25 chemical compounds, five of them representing 75.42% of the total obtained oil.
