      Abstract
      Bangle is one of aromatic plants which contains of essential oil. The aims of this research were to find essential oil from bangle rhizomes and fractions having potency as aromatherapy for antiobesity. The essential oil contained in the rhizome isolated using distilation method were 0.38-0.91% (v/w) based on wet weight. The potency of compound in crude essential oil, fraction 1, and fraction 4 as aromatherapy for antiobesity was tested in vivo on male Sprague-Dawley rats. Inhalation of crude essential oil, fraction 1, and fraction 4 showed lower response to body weight gain of rats than positive control group (cholesterol fed). Among the three inhalated groups, the rats inhalating fraction 4 had the lowest response to body weight gain, i.e. 37.34% (w/w). Based on analysis of terpenes by gas chromatography-mass spectrometry (GC-MS), the dominant compound in bangle essential oil and in fraction 4 is terpinene-4-ol, indicating that the compound is potential as an aromatherapy for antiobesity.
       
      Bangle merupakan salah satu tumbuhan aromatik yang mengandung minyak atsiri. Penelitian ini bertujuan mendapatkan minyak atsiri rimpang bangle dan fraksi yang terkandung di dalamnya yang berpotensi sebagai pelangsing aromaterapi. Kandungan minyak atsiri rimpang bangle hasil isolasi dengan metode distilasi air adalah 0.38-0.91% (v/b) berdasarkan bobot basah. Potensi senyawa yang terkandung dalam minyak atsiri kasar, fraksi 1, dan fraksi 4 untuk pelangsing aromaterapi diuji secara in vivo menggunakan hewan uji tikus putih jantan galur Sprague-dawley. Inhalasi minyak atsiri kasar, fraksi 1, dan fraksi 4 menunjukkan respons peningkatan bobot badan tikus yang lebih rendah dibandingkan tikus kelompok kontrol positif (pakan kolesterol). Dari ketiga kelompok tikus hasil inhalasi tersebut, tikus kelompok inhalasi fraksi 4 merupakan kelompok dengan respons peningkatan bobot badan terendah, yaitu 37.34% (b/b). Berdasarkan hasil analisis senyawa terpenoid dengan kromatografi gas-spektrometri massa (GC-MS), komponen terbesar yang terkandung dalam minyak atsiri kasar bangle dan fraksi 4 adalah terpinen-4-ol, maka senyawa tersebut berpotensi sebagai pelangsing aromaterapi.
