Abstract

ABSTRAKBawang hutan mengandung senyawa metabolit sekunder golongan naftokuinon (elecanacin, eleutherin, elutherol, eleutherinon) yang diketahui memiliki aktivitas antioksidan. Beberapa penelitian telah melaporkan tentang aktivitas antioksidan ekstrak yang diformulasi dalam bentuk sediaan tablet dan krim. Penelitian ini bertujuan mengembangkan formula dalam bentuk  mikroemulsi sebagai penghantaran yang efektif untuk mempertahankan aktivitas antioksidan ekstrak bawang hutan.  Mikroemulsi dibuat dengan menggunakan virgin coconut oil (VCO) sebagai fasa minyak, Tween 80 sebagai surfaktan dan gliserin sebagai kosurfaktan. Uji stabilitas fisik yang dilakukan terhadap sediaan meliputi uji organoleptik, pH, viskositas, sentrifugasi dan ukuran globul. Uji aktivitas antioksidan dilakukan secara in-vitro menggunakan metode peredaman DPPH dan menggunakan asam askorbat sebagai kontrol positif. Data hasil pengukuran dianalisis secara statistik menggunakan metode t-student. Hasil penelitian menunjukkan mikroemulsi dengan tampilan visual yang jernih dan ukuran globul < 5 μm. Meskipun sediaan mengalami perubahan pH dan viskositas tapi tidak terjadi pemisahan fase pada penyimpanan selama 28 hari. Hasil uji aktivitas antioksidan mikroemulsi ekstrak secara berturut-turut pada penyimpanan suhu 33°C dan 40°C: pada hari ke-1 menunjukkan nilai IC50 sebesar 101,167 μg/mL dan 89,956 μg/mL  sedangkan hari ke-35 sebesar 127,254 μg/mL dan 101,996 μg/mL. Berdasarkan hasil tersebut, aktivitas antioksidan ekstrak bawang hutan masuk dalam kategori kuat sampai sedang. Kata kunci  : Mikroemulsi, ekstrak bawang hutan (Eleutherine bulbosa (Mill.)Urb.), mutu fisik, antioksidan.  A B S T R A C TBawang hutan have contain secondary metabolite naftokuinon class (elecanacin, eleutherin, elutherol, eleutherinon) which known have antioxidant activities. Some of research reported antioxidant activity of extract which formulated in tablet and cream dosage form. The aim of this study was to developed effectively delivery system of bawang hutan in microemulsion  for maintenance its antioxidant activity. A microemulsion was prepared using an oil phase of  Virgin Coconut Oil (VCO), a surfactant of tween 80 and a  cosurfactant of gliserin. Evaluation of physical stability the microemulsions included analysis of organoleptic, viscosity, centrifugation and globul size. The antioxidant activities was evaluated by in vitro experiments using scavenging asssay of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and using ascorbic acid as positif control. The evaluation result were statistically analyzed using the t-student. The results indicated that a clear microemulsion and the globul size was < 5 μm. Even though, the pH and viscosity were not stable but there are not separated phase after centrifugation on 28 day storage. The antioxidant activity of microemulsion at 33°C dan 40°C storage respectively showed that IC50 values on day 1 is 101.167 μg/mL and 89.956 μg/mL, on day 35 is 127.254 μg/mL and 101.996 μg/mL. According to the result, antioxidant activity of bawang hutan extract is categorized into the powerful to moderate antioxidants. Keywords        :   Microemulsion, Eleutherine bulbosa extract (bawang hutan), Physical stability, Antioxidant.

Abstract

This research is about antipyretic effect of combination ethanol extract of sambiloto (Andrographis paniculata Burm.f. Nees.) herbsand ethanol extract of  belimbing wuluh (Averrhoa bilimbi L.) leaves in white male rats (Rattus norvegicus)which induced by 5 % pepton, in order to know the effect of combination and to determine the most effective dose as an antipyretic. Extract was prepared by maceration method using 70% ethanol. White rats were grouped into 7 difference treatment. Each rat was induced by using 5% peptone in dose of 250 mg/200 g Body Wight (BW). The first group was given Na CMC as a negative control. The second group was given paracetamol as a positive control. Groups of 3rd, 4th, 5th, 6th and 7th were given a combination of ethanol extract sambiloto (A. paniculata Burm.f. Nees.) herbs and ethanol extract belimbing wuluh (A. bilimbi L.) leaves in doses of (200 + 0) mg/200 g BW,  (150 + 50) mg/200 g BW, (100 + 100) mg/200 g BW, (50 + 150) mg/200 g BW, and  (0 + 200) mg/200 g BW, respectively. Temperature measurements of antipyretic were done for 3 hours in 30 minutes interval. Temperature data were statistically analysed using ANOVA (Analisys Of Variance) one way Anova method. The result of research was showed that combinationextract could reduce thefever. The most effective combination as an antipyretic was ethanol extract of sambiloto (A. paniculata Burm.f. Nees.) Herbs 150 mg and ethanol extract of belimbing wuluh (A. bilimbi L.) leaves 50 mg (150 + 50) mg/200 g BW. The dose has antipyretic effects that was not significant different to the positive control group(paracetamol treatment).

Abstract

Senyawa antioksidan dapat mengurangi efek buruk radikal bebas terhadap kulit. Daun kelor (Moringa oleifera Lam) mengandung senyawa antioksidan dengan potensi aktivitas yang kuat. Penelitian ini bertujuan untuk membuat sediaan gel antioksidan dengan menggunakan karbomer sebagai basis gel dan ekstrak etanol daun kelor dengan konsentrasi untuk F0, F1, F2 dan F3 adalah 0%, 1%, 2% dan 3%, yang kemudian dievaluasi dan diuji aktivitas antioksidannya. Pengujian aktivitas antioksidan dilakukan dengan metode penentuan IC50 menggunakan reaksi DPPH (Difenil-2-pikrilhidrazil). Hasil uji aktivitas antioksidan ekstrak etanol daun kelor adalah 89,305 ppm dan vitamin C sebagai senyawa pembanding adalah 8,374 ppm. Evaluasi sediaan gel meliputi pengamatan homogenitas, organoleptis (warna, aroma dan konsistensi), viskositas dan pH selama 28 hari. Aktivitas antioksidan ekstrak etanol daun kelor dalam sediaan gel dihari pertama adalah 129,245 ppm (F1), 116,875 ppm (F2) dan 97,484 ppm (F3), sedangkan dihari ke-28 adalah 178,236 ppm (F1), 148,589 ppm (F2) dan 143,333 ppm (F3). Hasil uji sifat fisik sediaan gel menunjukkan bahwa semua sediaan gel homogen dan tidak mengalami perubahan warna dan aroma, sedangkan konsistensi dari hasil uji viskositas mengalami perubahan signifikan setelah 28 hari dan hasil uji pH semua sediaan selain F3 juga mengalami perubahan signifikan setelah 28 hari. Berdasarkan hasil penelitian ini, disimpulkan bahwa ekstrak etanol daun kelor dapat diformulasi dalam sedian gel antioksidan dengan konsentrasi terbaik adalah 3%
