Abstract: The technology of immersing extraction and the formlation of composing purslane, bulrush root, sundew root, hawthorn and mint by orthogonal experiment was studied.Under the bolling condition, the results were achieved as: the amount of addition water to purslane,bulrush and sundew was 150ml, 150ml and 250ml respectively and the time of immersing extraction was 15min, 20min and 25min respectively.The immersing extraction technological paraneters of hawthorn and mint were respectively tmperature 45 ℃ and 65℃; amounts of addition water 120ml and 150ml;and time 450min and 15nin .The optinun composed drink was: purslane juice 46. 88% , bulrush juice 7. 03% , sundew juice 11. 2% , hawthorn juice 7. 5%,mint juice 11. 2% and 50% sirup 15 .2%.
