摘　　要：对抗生素S-A的热稳定性、酸碱稳定性、光稳定性和紫外稳定性进行了研究。结果表明,该抗生素对光照、紫外照射稳定性好,对热稳定性较好,60℃加热10 min其活性比率为83.1%;对酸碱较为敏感,pH值为6时,活性比率最大,为77.6%。Thermal, acid-base, light and UV stability of S-A antibiotic were studied. Result showed that this antibiotic was stable to light and UV and had relatively stable stability to thermal. The active ratio was 81.3 % under 60℃ after 10 min, S-A antibiotic was sensitive to acid-base. The active ratio was the biggest （ 77.6 % ） when pH value was 6.
