Abstract： Selenium is an essential trace element for human body， which cannot be synthesized by human body itself，so itneeds tobesupplementedbyexteralchannels.Seleniumrichteaisrich inselenium，andthehumanbody obtains selenium fromselenium rich tea mainly through the selenium dissolved in tea soup.The effcts of diffrent soaking time （5，10，15 min and 20min ）， brewing temperature （70， 80， 90°C and 100°C ）， tea-water ratio （1：40 ， and brewing times （1， 2， 3 times） on the leaching rate of selenium were investigated.Theresults showed that the leachingrate of selenium in selenium-rich tea was the highest when the soaking time was 10min ，the brewing temperature was 100‰ and the ratio of tea to water was 1：60（g：mL） ： And brew up to 2 times to achieve the purpose of selenium supplementation for the human body.
