Abstract

Acnes vulgaris is a chronic inflammatory disease of sebaceous follicles caused by Propionibacterium acnes and Staphylococcus epidermidis. The antibacterial activity of Impatiens balsamina L. has been studied for many years. The aims of this study are to find out the antiacne effect from methanolic extract of stems and leaves of Impatiens balsamina L. that formulated in gel. Simplicia were extracted using soxhlet technique bu using methanol as solvent. Extracts were then formulated in gel in three variations of HPMC 4000 and Carbopol 934 as gel base with ratio of 70:30 (F1), 50:50 (F2) and 30:70 (F3). The determination of antiacne effect was done using disc diffusion method. Evaluation of physical and chemical properties of those gels includes organoleptic examination, spreadability testing, adhesion testing and pH testing. Data were analyzed using R version 2.14.1 package R-commander. Determination results showed the diameter of inhibition zone from FI, FII and FIII for P.acnes are 6.46 ±0.15 mm; 12.16 ± 0.35 mm; 16.13 ± 0.35 mm and for S. epidermidis sebesar 14.5 ± 0.47 mm; 16.56 ± 0.651 mm; 17.13 ± 0.44 mm. Analysis results showed that gel of FIII gave optimal antiacne effect, and significantly different from positive control (p < 0,05). The evaluation of gel showed that they have homogeny texture, good spreadability and adhesion, as well as the pH.

Bahasa Abstract

Jerawat adalah penyakit peradangan kronis folikel sebasea yang disebabkan oleh bakteri Propionibacterium acnes dan Staphylococcus epidermidis. Tanaman pacar air (Impatiens balsamina L.) telah banyak diteliti aktivitasnya sebagai antibakteri. Tujuan dari penelitian ini adalah mengetahui efektivitas ekstrak metanol batang dan daun pacar air dan bagaimana efektivitas setelah diformulasikan dalam bentuk gel. Simplisia disokletasi menggunakan pelarut metanol. Ekstrak diformulasikan dalam bentuk gel dengan variasi konsentrasi basis HPMC 4000 dan Karbopol 934 dengan perbandingan 70:30 (Formula I), 50:50 (Formula II) dan 30:70 (Formula III). Pengujian aktivitas dilakukan dengan metode difusi cakram. Evaluasi sediaan meliputi pemeriksaan organoleptis seperti bau, warna, bentuk serta homogenitas, pengujian daya sebar, daya lekat dan pH. Analisis data menggunakan program R-Commander versi 2.14.1. Hasil penelitian menunjukkan daya hambat gel FI, FII dan FIII terhadap P. acnes sebesar 6,46 ±0,15 mm; 12,16 mm ± 0,35; 16,13 mm ± 0,35 mm dan terhadap S. epidermidis sebesar 14,5 ± 0,47 mm; 16,56 ± 0,65 mm; 17,13 ± 0,44 mm. Hasil analisis menunjukkan bahwa FIII memberikan efek antijerawat yang paling optimal dan berbeda signifikan bila dibandingkan dengan kontrol positif (p < 0,05). Hasil evaluasi menunjukkan sediaan homogen, memiliki daya sebar dan daya lekat yang baik, serta pH yang memenuhi syarat.
