[Abstract]
A method for the determination of adenosin in Jinshuibao capsule by TLC scanning was reported. The adenosin was saparated on sillica GF254 -CMC-Na2HPO4 plates with chloroform-ethyl acetate -isopropylalcohol-water-aqueous ammonia(8: 2: 6: 0. 5: 0. 12)as mobile phase,by CS-930 dual wave length TLC scanner in the swatooth scanning mode at λS=260nm and λR=300nm. Calibration graph was rectilinear between 0. 65~5. 20μg (r=0. 9995). The average recoveries were 99. 5% (n=3)and the coefficient of variation was 3. 7%.The method was simple,rapid and accurate.
