Abstract
Bunga telang (Clitoria ternatea L.) mengandung senyawa metabolit sekunder terutama flavonoid, fenolik, dan antosianin yang berpotensi sebagai antioksidan serta tabir surya alami. Penelitian ini bertujuan untuk mengetahui aktivitas antioksidan dan nilai Sun Protection Factor (SPF) pada sediaan lipbalm yang mengandung ekstrak etanol bunga telang. Ekstrak diformulasikan menjadi sediaan lipbalm dengan tiga konsentrasi ekstrak 0,08%, 0,09% dan 0,10% serta dievaluasi yang meliputi organoleptik, homogenitas, pH, daya sebar, dan daya lekat. Pengujian aktivitas antioksidan menggunakan metode DPPH serta penentuan nilai SPF secara spektrofotometri UV-Vis. Hasil Penelitian menunjukan bahwa nilai IC₅₀ ekstrak yaitu sebesar 141,952 ppm sedangkan pada Formula 1, Formula 2, dan Formula 3 berturut-turut sebesar 444,622 ppm, 409,534 ppm, dan 334,183 ppm termasuk dalam kategori sangat lemah. Nilai SPF ekstrak yaitu sebesar 14,829, 16,630 dan 16,895 termasuk kedalam kategori maksimal hingga ultra sedangkan pada formula yang diperoleh pada Formula 1, Formula 2, dan Formula 3 sebesar 7,274, 11,956 dan 13,216 termasuk kedalam kategori ekstra hingga maksimal. Seluruh formula memenuhi persyaratan evaluasi fisik dan Formula 3 menunjukkan aktivitas antioksidan yang lebih baik dengan kategori sangat lemah serta nilai SPF tertinggi. ------- Butterfly pea flower (Clitoria ternatea L.) contains secondary metabolites, particularly flavonoids, phenolics, and anthocyanins, which have potential as natural antioxidants and sunscreens. This study aimed to determine the antioxidant activity and Sun Protection Factor (SPF) value of lip balm preparations containing ethanol extract of butterfly pea flower. The extract was formulated into lip balm preparations at three extract concentrations: 0.08%, 0.09%, and 0.10%, and evaluated for organoleptic properties, homogeneity, pH, spreadability, and adhesion. Antioxidant activity testing was carried out using the DPPH method, and SPF values were determined by UV-Vis spectrophotometry. The results showed that the IC₅₀ value of the extract was 141.952 ppm, while Formula 1, Formula 2, and Formula 3 had IC₅₀ values of 444.622 ppm, 409.534 ppm, and 334.183 ppm, respectively, which are categorized as very weak. The SPF value of the extract was 14.829, 16.630, and 16.895, falling into the maximum to ultra category, while the SPF values obtained for Formula 1, Formula 2, and Formula 3 were 7.274, 11.956, and 13.216, respectively, falling into the extra to maximum category. All formulas met the physical evaluation requirements, and Formula 3 showed better antioxidant activity (categorized as very weak) along with the highest SPF value.
