Abstract
Objective: The aim of this study was to formulate an oral thin film strip (OTFS) contained the red dragon fruit peel (RDFP) ethanol extract (Hylocereus polyrhizus) and evaluate the characteristic, stability and antibacterial activity against Streptococcus mutans (S. mutans).
Methods: The film was made using the solvent casting method by adding a variety of concentration ethanol extract of red dragon fruit peel (5%, 10%, and 15%). The films were evaluated in organoleptic test, weight, thickness, pH, disintegration time, folding endurance, stability test and antibacterial activity.
Results: The results showed that the film provided a distinctive color, aroma, and taste of the extract. The result of film evaluation had weight between 0.07-0.21 g, thickness between 0.10-0.20 mm, pH between 5.70-5.99, disintegration time between 34.99-49.13 s, and folding endurance between 321.00-812.83 times. The films were stable for 2 mo at a variety storage temperature (4±2 ℃, 28±2 ℃, and 40±2 ℃). The films showed antibacterial activity for 5%, 10% and 15% with the diameter of inhibition 8.5 mm, 10.8 mm, and 12.9 mm, respectively.
Conclusion: Ethanol extract of RDFP can be utilized as a mouth freshener film that is stable for 2 mo and has antibacterial activity against S. mutans.
