Abstract
Daun sirsak mengandung senyawa alkaloid, saponin, tanin,
terpenoid, dan flavonoid yang berpotensi sebagai antioksidan. Ekstrak
daun sirsak diperoleh dengan metode maserasi menggunakan etanol 70%
dan diformulasikan dalam sediaan gel dengan variasi konsentrasi
propilen glikol, yaitu F1 (5%), F2 (10%), dan F3 (15%).
Sediaan gel diuji mutu fisiknya meliputi organoleptik,
homogenitas, pH, viskositas, daya lekat, daya sebar, serta stabilitas
menggunakan metode cycling test. Uji aktivitas antioksidan dilakukan
dengan metode DPPH menggunakan spektrofotometri UV-Vis dan
dianalisis secara statistik menggunakan one way ANOVA.
Hasil penelitian menunjukkan seluruh formula memenuhi
persyaratan mutu fisik sebelum dan sesudah uji stabilitas. Formula 2
dengan 10% propilen glikol memiliki konsistensi paling ideal dan stabil.
Ekstrak etanol daun sirsak memiliki aktivitas antioksidan sebesar 78,98
ppm yang tergolong kategori antioksidan kuat.
Soursop leaves contain alkaloid, saponin, tannin, terpenoid, and
flavonoid compounds that have antioxidant potential. Soursop leaf
extract was obtained by maceration using 70% ethanol and formulated
into a gel preparation with varying concentrations of propylene glycol,
namely F1 (5%), F2 (10%), and F3 (15%).
The gel preparation was tested for its physical quality, including
organoleptic properties, homogeneity, pH, viscosity, adhesiveness,
spreadability, and stability using the cycling test method. Antioxidant
activity was tested using the DPPH method with UV-Vis
spectrophotometry and statistically analyzed using one-way ANOVA.
The research results show that all formulas meet the physical
quality requirements before and after stability testing. Formula 2 with
10% propylene glycol has the most ideal and stable consistency. The
ethanol extract of soursop leaves has antioxidant activity of 78.98 ppm,
which is categorized as a strong antioxidant.
