摘要：
目的为口腔地米溃疡糊剂的质量标准提供质量浓度测定的依据。方法采用异烟肼比色测定口腔地米溃疡糊剂中地塞米松的质量浓度。结果地塞米松的质量浓度为6～16 μg/mL时，吸收度与地塞米松对照品质量浓度线性关系良好。地塞米松平均回收率为98.9%，地塞米松质量浓度相对标准偏差小于1%（n=5）。结论异烟肼比色测定地塞米松质量浓度简便易行、准确可靠。

Abstract:
Objective To provide content- measuring evidences for establishing the quality criteria of dexamethasone acetate ulcer pasta. Methods Content of dexamethasone acetate was assayed by the isonicotinyl hydrazine（INH） colorimetry. Results The good linear range was 6 - 16 μg/mL（r=0.999 1）. The average recovery of dexamethasone acetate was 98.9%, and relative standard deviation was low than 1%（n=5）. Conclusion It is easy, convenient, accurate and dependable for INH colorimetry to determine the content of dexamethasone acetate.
Key words: dexamethasone acetate, isonicotinyl hydrazine colorimetry, content assaying, ulcer pasta
