Abstract
The present invention provides methods for obtaining phenethyl isothiocyanate (PEITC), a natural glucosinylate derivative, from plant tissue. The methods involve selection of plant tissue naturally rich in PEITC, followed by aqueous extraction under conditions that promote optimal release of PEITC from the tissue. The invention further provides plant preparations containing significant quantities of PEITC and nutraceutical formulations comprising these preparations.
