Study on the Quality Stability of Rose Effervescent Tablets and Evaluation of Antioxidant Activity

This paper experimentally evaluates stability and antioxidant properties of rose effervescent tablets; investigatesthe six month stability of three batches of rose effervescent tablets sold in the market at room temperature. At thesame time, 1,1 diphenyl 2 trinitrophenylhydrazine (DPPH) was used in antioxidant experiment to compare rosetea with the same concentration and thereby evaluate the antioxidant activity of rose effervescent tablets. Theevaluation shows that the rose effervescent tablet prepared by this process is stable within 6 months, and thecontent of the six medicinal ingr edients and various indicators detected in the effervescent tablet are relativelystable without significant changes. Rose effervescent tablets have better scavenging effect on DPPH free radicalsthan rose tea with the same concentration. It shows that the prepared rose effervescent tablets have relativelystable quality and the preparation process is feasible, which provides a reference for the follow up long termstability experiment of rose effervescent tablets and related health products.
