| Abstract: | Objective:To revise the assay method hydroxypropoxy group of hydroxypropyl cellulose in Chinese Pharmacopoeia 2005 Edition.Method: GC was performed and the researches were verified. Results: The average recovery rate was 98.09%.The RSD in same laboratory of three determinations was 0.60%,the average RSD of three batch of samples by three different laboratories was 7.2% and the RSD of seven determinations of the same sample solution in 5 days was 1.23%.Conclusion: The method is proved to be accurate and convenient. |
