VITAMIN A OF EEL FISH (ANGUILLA MARMORATA) FROM PALU RIVER AND POSO LAKE

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
