Abstract

The leaf of “Ketapang” (Terminalia catappa L.) can be used as traditional medicine. The use of natural material is generally considered to be safer and has less side effect as compared to the use of modern medicine. This study aims at analysing the early elucidation of resistor property of the ethanol extract of the “ketapang” leaf against the growth of Staphylococcus aureus ATCC25923 as the cause of gingivitis, and to identify the active compound contained in the “ketapang” leaf. This study uses Complete Random Design (RAL) with 7 treatments of the extract concentration of “ketapang” leaf namely concentration of 1%, 2%,3%, 4%, 5%, positive control (chlorexidine) and negative control (ethanol). The discovery of the resistor efficacy of “ketapang” leaf extract against S. aureus bacteria using Kirby Beuer method has been indicated by the development of clear zone as the result of the application of anti-bacteria compound which is diffused in bacteria growth media. The finding of the study shows that the higher the concentration of the extract (5%), the wider the development of the zone of the resistor area. The effectiveness value of the anti-bacteria of “ketapang” leaf extract is not better than the antiseptic being tested. The result of profile test of phytochemical test shows that the extract of “ketapang” leaf contains tannin, saponin, terpenoid and flavonoid. The result of GC-MS test, it has been identified five compounds being contained in fraction IV namely Alpha Terpinolene, Cyclohexanol 5-methyl, Hexadecanoic acid, Octadecanoic acid, 1.2Benzenedicarboxylic acid. five active compounds that we found have the potentials of functioning as anti-bacteria.

Abstract

Hyperlipidimia merupakan suatu kelainan yang memicu terjadinya penyakit kardiovascular yang jumlah penderitanya cenderung mengalami peningkatan. Kelainan ini disebabkan oleh pola makan masyarakat yang cenderung mengkonsumsi makanan tinggi lemak, tetapi rendah kadar serat. Pemakaian obat paten, seperti simvastatin merupakan pilihan utama saat ini untuk mengatasi masalah tersebut. Namun, pemakaian obat ini dalam waktu lama tidak dianjurkan karena dapat menyebabkan efek samping merugikan bagi tubuh, sehingga perlu dicari bahan alam yang mempunyai efek sama dengan obat tersebut. Pada penelitian ini, potensi hypolipidemia daun salam diuji pada tikus jantan galur Wistar karena secara empirik daun tanaman ini sering dipakai sebagai obat tradisional. Tujuan penelitian ini adalah untuk mengetahui pengaruh ekstrak etanol daun salam (EEDS) dan rebusan daun salam (ARDS) terhadap menurunkan LDL-Kolesterol tikus galur Wistar. Penelitian ini menggunakan rancangan acak kelompok (RAK) dengan delapan kelompok perlakuan yaitu perlakuan dengan aquades (kontrol negatif), simvastatin 0,36 mg/kgBB (kontrol positif), EEDS 252mg/kgBB (EEDS 252), 504mg/kgBB (EEDS 504), 756mg/kgBB (EEDS 756), ARDS 25%/kgBB (ARDS 25), 50% mg/kgBB (ARDS 50), dan 75% mg/kgBB (ARDS 75). Perlakuan diberikan selama satu minggu pada tikus yang sebelumnya diberi pakan kaya lemak selama satu bulan. Hasil penelitian menunjukkan terjadinya penurunan kadar LDL-Kolesterol secara signifikan (p?0.05) pada semua kelompok perlakuan dengan kisaran potensi sebesar 8,00±0,82% sampai 56,16 ± 5,69% (< kontrol negatif dengan penurunan sebesar 6,25 ± 0,50%). Bahkan pada perlakuan 756mg/kgBB EEDS (EEDS 756) menunjukkan hasil yang lebih baik (p?0.05) daripada kontrol positif (simvastatin). Efek hypolipidemia dari ekstrak daun salam ini diduga disebabkan oleh golongan senyawa-senyawa flavonoid, alkaloid, dan tannin yang terkandung dalam ekstrak daun salam. Kata kunci: Daun salam, LDL-Kolesterol, Tikus Wistar
