Abstract
Background & Objective: Eel fish (Anguilla marmorata) has high nutritional or nutrition advantages such as protein, minerals, fatty acids and one of them is vitamin A. This study aims to compare the amount vitamin A of eel fish (Anguilla marmorata) phase glass eel, yellow eel, silver eel from Palu River and Lake Poso. Materials and Methods: The materials used in this research are eel fish (Anguilla marmorata) Glass eel, Yellow eel, Silver eel size from Palu River and Lake Poso, Ethanol, KOH, n-Hexane, BHT (Butyl Hydroxyl Toluene), Methanol. The sampling technique uses purposive sampling based on the type of weight, size and location of the taking. The method used is High Performance Liquid Chromatography (HPLC) where previously conducted saponification test (saponification) on sample of eel fish. Results: The result of vitamin A test on eel fish from Palu River phase of glass eel is 4.01 mg / kg (1336,67 IU / 100 gram), yellow eel 7,26 mg / kg (2420 IU / 100 gram), silver eel equal to 9.73 mg / kg (3243,34 IU / 100 gram). Vitamin A in eels from Lake Poso phase of glass eel of 0.22 mg / kg (73.34 IU / 100 gram), yellow eel 7.16 mg / kg (2386.67 IU / 100 gram), silver eel of 11 , 3 mg / kg (3766.67 IU / 100 gram). Conclusion: vitamin A of eel fish content from Palu River and Lake Poso were significantly different, which was based on p <0,05

Summary
Vitamin A merupakan istilah umum bagi sebuah kelompok senyawa kimia yang secara struktural saling berhubungan dan dikenal dengan nama retinoid, kelompok retinoid ini secara kualitatif mengendalikan aktivitas biologis retinol. Adaptasi homeostatik dan pendaur ulangan ini berfungsi untuk mempertahankan kadar vitamin A yang relatif konstan dalam darah sampai simpanan di dalam tubuh terpakai di bawah nilai batas yang menentukan (Gibney Michael J, ddk , 2009). Sumber vitamin A yang sudah terbentuk (preformed) dalam makanan, meliputi hati susu dan produk susu, telur, serta ikan, sumber vitamin A yang paling kaya adalah minyak hati misalnya pada ikan air tawar Selain itu menurut hasil penelitian laboratorium perikanan kandungan gizi yang terdapat dalam ikan sidat ini terdiri atas 303 gram kalori, 14,0 gram protein, 19,0 gram lemak, 200 gram fosfor, 20 gram zat besi , 4700 IU/100 gram vitamin A, 0,10 mg vitamin B, 2,0 mg vitamin C, dan kadar air 58 gram (Affandi, 2001). Kabupaten Lamongan memiliki kadar vitamin A yang lebih tinggi dari pada ikan bandeng air payau Kabupaten Bangkalan. Danau Poso mengingat masih kurangnya informasi mengenai kadar vitamin A yang terdapat pada ikan sidat dan mengetahui perbandingan pada 3 fase yaitu fase glass eel, yellow eel dan silver eel
