Abstract:
After extracting completely morphine and codeine from opizoic tablets with a mixture of 3 volumes of isopropanol and 7 volumes of chloroform, an HPLC method was used to determine simultaneously morphine and codeine in the extracts. The HPLC technique was carried out on the column Lichrosorb (4x250mm, 10m) with diode array detector or UV-detector at =285 nm and a mixture of 42 volumes of 0.24% sodium heptanesulfonat solution adjusted to pH=3.2 by phosphoric acid and 18 volumes of Acetonitrile as mobile phase at flow rate 1.0ml/min. The experimental results proved that the proposed HPLC method was rapid, specific, accurate and precise.
