Abstract: The stability of penicillin Gskin allergy test solution and penicillin Gconcentrated solution stored at low temperature was determined by RP-HPLC.The results showed that penicillin G was much more stable in dilute solution than in concentrated solution,and that the pHvalues decreased with the lapse of time,and that degradation rate of penicillin G in solution increased with decrease of pH.

Key words: HPLC, penicillin G, allergy test
