Abstract

Senyawa aktif dalam buah kersen memiliki potensi sebagai antioksidan dan dapat berfungsi sebagai fotoprotektif diantaranya flavonoid dan senyawa fenolik lainnya. Kelemahan senyawa dari bahan alam bersifat termolabil, sehingga memerlukan modifikasi enkapsulasi untuk memperoleh potensi yang maksimal.  Penelitian ini bertujuan untuk mengetahui aktivitas antioksidan dan efek fotoproteksi nanoenkapsulasi ekstrak etanol buah kersen (Muntingia calabura L.) dengan variasi konsentrasi kitosan. Ekstraksi simplisia menggunakan metode maserasi dengan etanol 96% dan formulasi nanoenkapsulasi menggunakan metode gelasi ionik dengan kitosan 0,1%; 0,15%; dan 0,2%. Pengujian yang dilakukan yaitu skrining fitokimia, uji ukuran partikel dengan Particle Size Analysis (PSA), analisis gugus dengan FTIR, aktivitas antioksidan dengan metode DPPH, dan penentuan nilai Sun Protection Factor (SPF). Hasil yang didapatkan pada uji ukuran partikel dari ketiga formula masuk dalam rentang ukuran nanoenkapsulasi 1-1000 nm dan ukuran yang paling baik pada Formula II yaitu 152,8±9,5 nm. Hasil analisis gugus fungsi nanoenkapsulasi ekstrak etanol buah kersen menunjukkan serapan milik kitosan dan ekstrak dengan memuculkan dua serapan dominan pada bilangan gelombang 1629,79 cm-1 yang menunjukkan adanya gugus bending N-H dan 3261,42 cm-1 yang menunjukkan adanya serapan gugus hidroksil yang tumpang tindih dengan vibrasi streching N-H. Aktivitas antioksidan yang dilihat dari IC50 dari ketiga formula nanoenkapsulasi ekstrak etanol buah kersen termasuk kategori sangat kuat yaitu Formula I (9,57±0,02 mg/L), Formula II (9,45±0,01 mg/L), dan Formula III (9,05±0,04 mg/L). Nilai SPF yang diperoleh oleh Formula I, II, III secara berturut-turut yaitu 12,1828±0,0045; 14,3430±0,0008; dan 14,7285±0,0091.

Abstract

Bitter melon fruit (Momordica charantia L.) can be used as traditionally to reduce blood sugar levels. Avicel PH 101 and corn starch are efficacious as fillers, disintegration excipient and binders. The combination of Avicel PH 101 with corn starch is expected to be able accelerate the tablet disintegration time of tablet. This research was aimed to get the optimum formula tablets of bitter melon extract tablets using combination of corn starch and avicel PH 101. Bitter melon extract was formulated in tablet with wet granulation method. Bitter melon extract was obtained by maceration with ethanol 70% as solvent. Tablet formula based on the Simplex Lattice Desaign method uses Design Expert software version 11 with parameters that are used weight uniformity, hardness, friability and disintegration time. The results obtained from the simplex lattice design compared with the results of testing using the SPSS 18 program using the One Sample T-Test with a confidence level of 95%. The result of this research indicate bitter melon extract was made by tablets with wet granulation method with a combination of Avicel PH 101and corn starch, a formula with a ratio of 51% : 49% selected as the optimum formula with weight uniformity, hardness, friability and disintegration time meeting the requirements. Keywords : bitter melon extract, tablets, corn starch, avicel PH 101, simplex lattice design

Abstract

Gel is a semisolid preparation that is clear, translucent containing active ingredients, can provide a cool effect on the skin and good spread of the skin. The use of gelling agent in gel formulations greatly affects the physical properties of the resulting gel preparations. HPMC is a gel forming material that is neutral and can form a clear gel and can maintain the viscosity of the resulting gel, while carbopol are easily dispersed in water and produce preparations with sufficient viscosity. The research conducted aims to determine the comparison of carbopol and HPMC in the optimal gel formula of betel leaf extract nanoparticles with Simplex Lattice Design method. The response used was pH, viscosity, spreadability, adhesion and antibacterial activity against Staphylococcus aureus. The results obtained by carbopol concentration of 80.9% and HPMC 19.1% was the optimal gel formula of betel leaf extract nanoparticle. Based on the verification, an insignificant difference was obtained between the predictions of the software and the results of the tests performed. This shows that the method used was valid or can be trusted.
