Abstract:
Objective:To optimize the formula of film-forming materials for compound rhizoma corydalis plastics. Methods:Poly-vinyl alcohol 124 (PVA124) and bletilla striata gum were selected as the film-forming materials. The amounts of PVA 124, bletilla striata gum, glycerol and absolute ethanol were used as the influencing factors in an orthogonal test with the composite score of film-forming time and appearance as the indices to screen out the best composition of film-forming materials. Results:The best composition of film-forming materials was as follows:8 g PVA 124, 1 g bletilla striata gum, 2 ml glycerol and 15 ml ethanol. Conclusion:The op-timized film-forming materials can be used for the preparation of compound rhizoma corydalis plastics.
