目的:通过对健骨膏稳定性的考察,决定其有效期。方法:采用高效液相色谱法测定软膏中血竭素的含量,考察湿度、光照及温度对健骨膏稳定性的影响。结果:健骨膏对湿度和强光照射不敏感,预测其有效期为1.5 a。结论:本研究为贮存和应用提供了理论依据。
OBJECTIVE: To determine the period of validity of the bone-strengthening ointment by investigating its stability. Methods: The content of dracorhodin in ointment was determined by high performance liquid chromatography (HPLC). The effects of humidity, light and temperature on the stability of ointment were studied. Results: The bone-strengthening cream is insensitive to humidity and light irradiation, and its effective period is predicted to be 1.5 years. Conclusion: This study provides a theoretical basis for storage and application.
