Uji Aktivitas Antibakteri Ekstrak Etanol Daun Rambutan (Nephelium lappaceum L) Pada Pertumbuhan Bakteri Staphylococcus aureus dan Escherichia coli

Abstract

The purpose of this study was to determine that the ethanolic extract of rambutan leaves (Nephelium lappaceum L) has antibacterial activity against Staphylococcus aureus and Escherichia coli bacteria. As an antibacterial comparator used Amoxicillin. Each leaf of sample was extracted with maceration methode using 70% of ethanol solvent. Where it 2 to 3 days with several stirring times then it filtered, then the filtrate result was thickened with vacuum rotary evaporator. The antibacterial activity test used the paper disc diffusion method and was observed based on the diameter of the inhibition zone or the clear zone formed around the paper discs and slots which used with three times treatments. Result test of antibacterial activity of rambutan leaf ethanol extract (Nephelium lappaceum L) with these method showed that the extract actively inhibited the growth of Staphylococcus aureus bacteria with Minimum Inhibitory Concentration (MIC)3.125% with a 7.96 mm, but not showed for the growth of Escherichia coli bacteria.

UJI AKTIVITAS ANTIBAKTERI EKSTRAK ETANOL 96% DAUN RAMANIA (Bouea macrophylla Griffith) TERHADAP BAKTERI Staphylococcus aureus

“…Bakteri gram positif yang terjadi pada kulit dan selaput lendir manusia. Hampir setiap orang pernah mengalami berbagai infeksi Staphyloccus aureus selama hidupnya dari keracunan berat atau infeksi kulit kecil sampai yang tidak bisa disembuhkan (Maradona, 2015).…”

Comparative Analysis of the Antifungal Efficacy of Tomato Leaves (Lycopersicum esculatum Mill) at Concentrations of 25% and 70% on the Growth of Candida albicans

“…Different groups were compared based on the diameter of their inhibitory zones using univariate and bivariate analyses, with a significance threshold of p<0.05. rendering it a very efficacious option for addressing many fungal infections. [9][10][11][12][13][14] According to the study findings, nystatin is superior to tomato leaf extract when used at doses of 25% and 70%. However, due to the potential hazard of systemic toxicity, nystatin is limited to use on the skin, vagina, and mouth.…”

Karakteristik Kimia Teh Daun Rambutan Aceh (Nephelum Lappaceum L) Dengan Variasi Suhu Dan Waktu Pengeringan

“…Berdasarkan hasil identifikasi flavonoid, daun rambutan positif mengandung senyawa flavonoid yang ditandai dengan perubahan warna menjadi kemerahan setelah direaksikan dengan serbuk Mg dan HCl. Hal tersebut sesuai dengan penelitian yang dilakukan Maradona (2013) bahwa daun rambutan mengandung senyawa flavonoid. Berdasarkan hasil identifikasi sponin diketahui bahwa sampel positif mengandung senyawa saponin.…”
