<p>Kejadian infeksi, baik di lingkungan rumah sakit yang disebut infeksi nosokomial maupun di luar rumah sakit, cukup besar. Infeksi mempertinggi angka kematian dan kesakitan, serta memperlama waktu perawatan di rumah sakit. Saat ini banyak tanaman yang terbukti secara empiris memiliki efek antibakteri, diantaranya adalah minyak kelapa murni (<em>Virgin Coconut Oil / </em>VCO<em>)</em>, oleh karena itu perlu dilakukan penelitian ini guna mengetahui efek anti bakteri VCO pada luka yang telah diinfeksi dengan <em>Methicillin Resistant Staphylococcus aureus </em>(MRSA).</p><p>Telah dilakukan penelitian eksperimental laboratorium dengan desain penelitian Rancangan Acak Lengkap. Hewan coba yang digunakan adalah marmut jantan galur albino sebanyak 15 ekor . Dermis hewan coba diinsisi hingga diperoleh luka berukuran 9cm<sup>2 </sup>dasar otot, luka diinfeksi dengan suspensi bakteri MRSA, kemudian diberi 3 macam perlakuan yaitu dibiarkan saja tanpa pengobatan untuk control negatif, terapi VCO per oral 3 cc / hari dan terapi VCO topikal 0,4 cc / hari. Data yang diperoleh dianalisis dengan <em>analysis of variance </em>(ANOVA) dan <em>two sample – T test.</em>Hasil penelitian menunjukkan bahwa pemberian VCO topikal dengan dosis 0,4 cc / hari mampu mengobati infeksi dan mempercepat penyembuhan luka hewan coba secara bermakna (p = 0,043 &lt; α = 0,05), tetapi pemberian VCO peroral 3 cc / hari menunjukkan hasil yang tidak bermakna (p = 0,376 &gt; α = 0,05). Pemberian VCO per oral 3 cc / hari dan topikal 0,4 cc / hari mampu menurunkan jumlah lekosit darah pada hewan coba. Pemberian VCO topikal 0,4 cc / hari mampu membunuh bakteri sehingga dapat mengurangi jumlah bakteri pada luka secara bermakna (p = 0,0092 &lt; α = 0,05), namun pemberian VCO per oral tidak mampu mengurangi jumlah bakteri pada luka secara bermakna (p = 0,17 &gt; α = 0,05). Pada hasil penelitian di atas, dapat disimpulkan bahwa pemberian VCO topikal menunjukkan efek antibakteri yang bermakna untuk mengatasiinfeksi MRSA.</p>

Purpose. This study describes the antibacterial effect of extracts and compounds isolated from the aerial part of Chelidonium majus Linn. (Papaveraceae) acting against clinical strains of methicillin-resistant Staphylococcus aureus (MRSA). Methods. The activities were evaluated by using the macrobroth dilution method and reported as the MICs/MBCs. Results. Bioassay-guided fractionation of the most active extract from the aerial parts (EtOAc) led to the isolation of benzo[c]phenanthridine-type alkaloids 8-hydroxydihydrosanguinarine (hhS), 8-hydroxydihydrochelerythrine (hhC), which were potently active against MRSA strains. Conclusions. The selective antibacterial activity reported in this paper for 8-hydroxylated benzo[c]phenanthridine-type alkaloids isolated from C.majus opens the possibility that they could be helpful for the developing of new antibacterial agents for treating the infection of MRSA which has created nosocomial problem worldwide.

Background: Hibiscus sabdariffa known as roselle, which belongs to the family Malvaceae, grows in sub-tropical and tropical region including Indonesia. Several studies have reported the benefits of roselle for health. Roselle extract has been shown to have antibacterial effect as a support for antibacterial therapy, especially for case of antibiotic resistance, and antioxidant effect which can neutralize free radicals. Purpose: The aim of this study was obtaining the minimum inhibitory concentration (MIC) and inhibition concentration (IC50) of roselle extract. Methods: Antibacterial effect of roselle extract against Methicillin-Resistant Staphylococcus aureus (MRSA) was tested in nutrient agar media using diffusion method. Antioxidant activity of roselle extract was performed by DPPH. The violet color of DPPH solutions that was reduced by roselle extract were measured using visible spectrophotometer at the wavelength of 516 nm. Result: The result of this study obtained the (MIC) and IC50 of roselle extract were 2,5% and 1251±202,32 ppm, respectively. Conclusion: It can be concluded that roselle extract have antibacterial effect against MRSA and antioxidant effect.
