Abstract :
Papaya seeds are one of the traditional medicines that are useful as an
antioxidant. The flavonoids which are contained in papaya seeds can reduce free
radicals. It can also induce the inflammatory mediators that have potential to make
hepatocyte cell is damaged. In the formulation, the researcher chooses patch
preparations to enhance bioavailability, provide long-term drug effect and release
the drug at a constant dose. This study aims to determine how much the
concentration of PVA base is needed in producing the papaya seeds extract
patches with good physical stability. Papaya seeds extract was obtained through
extraction by maceration method with ethanol 95% solvent. In this test, the
variations of PVA concentrations in patches are 6%, 7%, and 8%. Physical
stability tests were carried out on days 0, 7, 14, 21, and 28. Those are organoleptic
tests (shape, color, odor and taste), weight uniformity test, homogeneity test, pH
test, thickness test, drying shrinkage test and folding endurance test. The
acceptability test was conducted on 10 respondents. The parameters of the test are
whether the patch color is equal and there are no color patches on the patch?s
surface, whether the patch is flexible, whether the patch?s surface is smooth and
whether the patch?s surface is not oily. From three formulas, the best physical
results is F1 with a PVA concentration of 6% with the results: weight uniformity
of 0,47 ± 0,01 g; thickness 0,02 ± 0; pH 6 ± 0; shrinkage drying 0%. The
acceptability test on F1 with 6% PVA concentration is more acceptable for people
in society. It shows on the results of the weight uniformity test and the pH test on
the three PVA concentrations which do not affect between formulas, while the
thickness test affects between formulas.
