| Abstract: | Aspirin,paracetamol and caffeie in compound aspirin tablets were determined byusing zero-crossing derivative spectrophoton1etry（ CDS）and multiwave-length coefficient spec-trophotometry（MCS）without being separated.The recovery for these components was 99.18%,100. 81%,98. 87%to ZDS and 99.81%. 100.38%, 99. 87%to MCS respectively. The RSD forthem was 1.1%,0.8%,1.4%to ZDS and 1,0%,0.3%,0.9%to MCS respectively. |
