Abstract��
OBJECTIVE: The stability of phospholipid capsules was preliminarily studied. METHOD: The appearance,disintegration time,color of alcohol solution,content and degradation products were observed and analyzed under the test of influencing factors,accelerating test,inspecting test at room temperature and low temperarure,respectively.And the results were compared with those at 0 hour. RESULTS: Under 60, the capsules became deformed and broken.The color of the content became dark.The degradation products appeared at the tenth day.Under 40 with RH 75%,degradation products appeared.The color of content became dark in the first month,the second month and the third month, respectively.disintegration time was prolonged in the third month. CONCLUSION: The phospholipid capsules were unstable at high temperature and high hAuthor umidity, but stable under other inspecting conditions.
