RUBUS COREANUS EXTRACTS HAVING THE INCREASED IMMUNITY-ACTIVITY BY ULTRASONIFICATION LOW-TEMPARATURE EXTRACTION

摘要

Rubus fruit extract and a fractionation stage by the ultrasonic wave extracting in low temperature with increased immune activity are arranged to show higher immune activity and increased cell differentiation by the difference of multistep by the increase of difference-induced material. Rubus fruit is in 60deg.It is r for 24 hours that C, which is extracted in distilled water, is ultrasonically extracted as 30min in 40KHz and is fractionated with chloroform, ethyl acetate and butanol in order. For an example, Rubus fruit is washed, and 25 Dao 30deg. in a shade and groundC is dried to 150meshes. Rubus fruit powder is in 100deg.It is 12hr that C, which is extracted in water, and 30min, filtering and reduced pressure are ultrasonically extracted as at 40 kilo hertzs. By fractionation step by step comprising using chloroform, ethyl acetate and butanol in order are concentrated under reduced pressure and are dried in vacuo Rubus fruit concentrate.
