Determinação de alfa-Tocoferol em alho irradiado utilizando cromatografia líquida de alta eficiência (CLAE)
The effects of 60Co ionizing radiations in doses of 0, 75, 100, 150, 200 and 250Gy on garlic, upon the alpha-tocopherol concentration were studied. The alpha-tocopherol contents were established by high performance liquid chromatography (HPLC), after direct hexane extraction from the garlic samples. The alpha-tocopherol was determined through normal-phase column, and mobile phase was composed by hexane: iso-propyl alcohol (99:01 v/v), with 2mL/min flow rate and fluorescence detector. It is statistically shown that an irradiation dose of up to 150 Gy does not affect the garlic alpha-tocopherol content.
