Abstract: In order to optimize the stability of Tilmicosin in acid and alkali, the contents of Tilmicosin were determined by HPLC to estimate the degradation of Tilmicosin in different pH conditions. The results showed that Tilmicosin was stable in pH 2 to 7.4.The degradations of Tilmicosin in pH 0.5 and pH 13 were 11.4% and 50.2%, respectively. Tilmicosin was not stable in concentrated acid and alkali,it would be partial degradable.

Key words: Tilmicosin; acid; alkali; stability; HPLC
