Abstract: The compound,4,5-benzo-selenium was extracted by 2,3 DAN mixed with quadrivalence selenium from the samples by means of the catalyst,cyclo-hexane under the condition of pH 1.5~2.0.The minim selenium from the eucommia seed was determined by fluorometry.The manipulation is simple and sensitive,which can obtain accurate result and good reproductivity.

Key words: DAN, fluorometry, eucommia seed, selenium
