Abstract

Radikal bebas merupakan senyawa yang bersifat tidak stabil dan berbahaya bagi tubuh untuk mengurangi efek negatifnya diperlukan senyawa antioksidan. Daun sirih merah (Piper ornatum.) merupakan salah satu bagian tanaman yang mengandung senyawa antioksidan berupa flavonoid. Tujuan penelitian ini adalah untuk mengetahui aktivitas antioksidan pada sediaan emulgel ekstrak daun sirih merah dengan variasi konsentrasi HPMC. Ekstrak daun sirih merah dengan metode maserasi menggunakan etanol 96%. Ekstrak kemudian diibuat sediaan emulgel dengan variasi gelling agent HPMC sebagai berikut: F1, F2, F3% berturut-turut konsentrasi 3%, 5%.7%. Formulasi sediaan emulgel dievaluasi sifat mutu fisik meliputi organoleptis, homogenitas, pH, viskositas, daya sebar dan daya lekat, kemudian dilakukan uji stabilitas menggunakan metode cyling test, selanjutnya ekstrak dan formula emmulgel diuji antioksidan dengan metode DPPH (2-2-difenil-1- pikrilhidrazil). Data dianalisis secara statistic dengan aplikasi SPSS. Hasil penelitian menunjukkan bahwa sediaan emulgel antioksidan daun sirih merah dengan variasi HPMC memenuhi parameter uji mutu fisik emulgel. Sediaan emulgel daun sirih merah memiliki aktivitas antioksidan. Formula 3 merupakan formula yang terbaik karena memiliki uji mutu fisik yang baik dan uji stabilitas yang baik yang meliputi uji organoleptis, uji homogenitas, uji tipe emulsi, uji pH, uji viskositas, uji daya sebar dan uji daya lekat serta mempunyai aktivitas antioksidan yang baik sebesar 43,389 ppm. Free radicals are compounds that are unstable and harmful to the body. Antioxidant compounds are needed to reduce their negative effects. Red betel leaf (Piper ornatum.) is one part of the plant that contains antioxidant compounds in the form of flavonoids. The purpose of this study was to determine the antioxidant activity of emulgel preparations of red betel leaf extract with various concentrations of HPMC. Red betel leaf extract by maceration method using 96% ethanol. The extract was then made into emulgel preparations with various HPMC gelling agents as follows: F1, F2, F3%, respectively, concentrations of 3%, 5%, 7%. The emulgel formulation was evaluated for its physical quality including organoleptic, homogeneity, pH, viscosity, spreadability and adhesion, then a stability test was carried out using the cyling test method, then the emmulgel extract and formula were tested for antioxidant using the DPPH method (2-2- diphenyl-1- picrylhydrazyl). Data were analyzed statistically with the SPSS application. The research results showed that the red betel leaf antioxidant emulgel preparation with HPMC variations met the physical quality test parameters of emulgel. Red betel leaf emulgel preparation has antioxidant activity. Formula 3 is the best formula because it has good physical quality tests and good stability tests which include organoleptic tests, homogeneity tests, emulsion type tests, pH tests, viscosity tests, spreadability tests and adhesiveness tests and has good antioxidant activity of 43,389 ppm.
