Abstract
Abstract Inflammation and fever are a normal protective response of tissue injury. Inflammation and fever usually treated with nonsteroidal anti-inflammatory drugs (NSAIDs). This drug has analgesic and antipyretic effect. At higher doses this drug can act as anti-inflammatory agent. Longan leaves (Dimocarpus longan Lour) contains flavonoid which assumed has anti-inflammatory and antipyretic effects. This study aims to determine the effect of anti-inflammatory and antipyretic effects of ethanol extract of Longan leaves (Dimocarpus longan Lour) in male white rats (Rattus norvegicus). Longan leaves were extracted using ethanol 96% with ratio 1:10. The effect of anti-inflammatory and antipyretic of this extract was tested in each group of rats : the negative control, the positive control and the test group which was given with extract  (200 mg/kg and 400 mg/kg). Carrageenan and DPT-Hb vaccine used as induction of inflammatory and pyretic reaction in this experiment. The results showed that ethanol extract of Longan leaves (Dimocarpus longan Lour)  has antipyretic effects at dose 200mg/kgBW, and antipyretic effect at dose  400mg/kgBW.

Intisari Peradangan (inflamasi) dan demam adalah respon protektif normal pada cedera jaringan. Penanganan inflamasi dan demam biasanya dapat dilakukan dengan diberikan obat antiinflamasi nonsteroid (NSAID). Obat ini memiliki efek analgesik, antipiretik, dan pada dosis tinggi dapat berefek sebagai anti-inflamasi. Daun lengkeng (Dimocarpus longan Lour) mengandung flavonoid yang diduga memiliki efek anti-inflamasi dan antipiretik. Penelitian ini bertujuan untuk mengetahui pengaruh efek anti-inflamasi dan antipiretik ekstrak etanol daun lengkeng (Dimocarpus longan Lour) pada tikus putih jantan (Rattus norvegicus). Ekstrak daun lengkeng didapatkan dengan cara ekstraksi menggunakan etanol 96% dengan rasio 1:10. Pengujian efek antiinflamasi dan antipiretik masing-masing dibagi menjadi empat kelompok, yaitu kelompok kontrol negatif, kelompok kontrol positif dan kelompok uji ekstrak etanol daun lengkeng (Dimocarpus longan Lour) dosis 200 mg/kgBB dan 400 mg/kgBB. Induksi pada uji antiinflamasi dan antipiretik menggunakan karegenan 1% dan vaksin DPT-Hb. Hasil penelitian menunjukkan bahwa ekstrak etanol daun lengkeng (Dimocarpus longan Lour) dosis 200mg/kgBB menghasilkan efek antipiretik, sedangkan ekstrak etanol daun lengkeng (Dimocarpus longan Lour) dosis 400mg/kgBB menghasilkan efek anti-inflamasi.
