Abstract: Objective To prepare Garcinia glycosides sustained-release tables and study their in vitro release characteristics. Methods Garcinia glycosides sustained-release tablets were prepared by hydroxypropylmethyl cellulose (HPMC) as gel matrix material and ethyl cellulose (EC) as skeleton material. Factors influencing the release rate of Garcinia glycosides from the sustained-release tablets, such as pH of release medium, skeleton material and amount of HPMC, porogen of type and amount, and tabletting pressure, were studied. Results Garcinia glycosides release rate was controlled obviously by the specifications and amount of skeleton material and porogen type. While the influence of pH, speed and tabletting pressure had certain influences to the release rate. Conclusion The selected formulation of Garcinia glycosides sustained-release tablets was reasonable with good controllability and reproducibility.
