Abstract

The present study was aimed to predict the level of toxicity of aqueous fraction of Impatiens balsamina by acute toxicity study using OECD guideline 425. Female Sprague Dawley 8-12 week and weight between 140-170 gram were used, the amount of experimental rats were 10 rats. Rats were sequentially administered all the fraction in single dosage (limit test) of 2000 mg/kg body weight and 5000 mg/kg of body weight. All the animals were individually studied for mortality, wellness parameters, food consumption,water consumption, body weight. Histopathological examination was done on the liver and kidney. The result of this study showed that no mortality and no significant changes were observed in wellness parameter, body weight, food consumption, and water consumption at 2000 and 5000 mg/kg of body weight for 48 hour and 14 days. Histopathological examination of fraction treated groups showed lesion of hepatic cells. Based on the result of this research, the researcher conclude that LD50 of aqueous fraction of Impatiens balsamina L was greater than 5000 mg/kg of body weight, which is classified as mild toxic.

Bahasa Abstract

Penelitian ini bertujuan untuk memprediksi tingkat toksisitas dari fraksi air herba pacar air dengan pengujian toksisitas akut menggunakan pedoman OECD 425. Tikus betina galur Sprague Dawley umur 8-12 minggu dengan berat 140-170 gram digunakan pada penelitian ini, jumlah hewan uji sebanyak 10 ekor. Tikus secara berurutan diberikan fraksi air herba pacar air dosis limit test yaitu 2000 mg/kgBB dan 5000 mg/kgBB, diberikan secara oral dengan dosis tunggal. Hewan uji secara individul diamati kematian, pengamatan klinis, pengamatan berat badan, konsumsi makan dan minum serta histopatologi hati dan ginjal. Pengamatan dilakukan pada 48 jam dan dilanjutkan 14 hari. Hasil penelitian menunjukkan tidak terjadi kematian pada hewan uji, tidak terdapat perubahan yang signifikan pada pengamatan klinis, berat badan, konsumsi makan dan minum pada dosis 2000 mg/kgBB dan 5000 mg/kgBB pengamatan 48 jam maupun pengamatan 14 hari. Hasil pengamatan histopatologi hati menunjukkan adanya kerusakan berupa lesi. Berdasarkan hasil penelitian dapat disimpulkan bahwa fraksi air herba pacar air memiliki LD50 lebih dari 5000 mg/kgBB, yang tergolong dalam toksik ringan.
