Title Statement Analysis and dosage formulation of the vitamin A content of the liver oil of Pangasius buchanani kanduhito valenciennes Physical Description 21-23 Summary, Etc. The aim of this study was to determine the Vitamin A (Retinol Palmitate) content of Pangasius buchanani Kanduhito liver oil. The initial step in the study is to acquire fresh Pangasius liver to be extracted by reflux distillation using petroleum ether as the solvent. Preliminary test and confirmatory test for the presence of Vitamin A were conducted. The oil obtained from the extraction was heated using a steam bath to remove the last traces of the solvent. With the extracted oil, physical test and chemical tests were conducted. The physical tests include organoleptic test, solubility, specific gravity, refractive index. The chemical tests were divided into two, qualitative tests (identification/confirmatory test for Vitamin A, determination of the acid value, saponification value, unsaponified matter, and ester value) and qualitative test which involves the chemical assay of the Vitamin A content of the Pangasius liver oil extractive using High Pressure Liquid Chromatography. Results showed that Vitamin A is present in the Pangasius liver oil extract. Pangasius liver a percentage yield of 25% with macerating the sample for 48 hours followed by reflux distillation method using petroleum ether as solvent. The physical properties of Pangasius liver oil extractive comparable to the properties of Lapu-Lapu liver oil extractive, cod liver oil, and halibut liver oil. The chemical properties show a light deviation from those listed under the above mentioned oils but are nevertheless within acceptable range. Finally, the Pangasius liver oil extractive contains higher vitamin content (97 I.U. /g) than the milkfish liver oil (1.8 I.U. /g.) making it an alternative source of Vitamin A Subject Added Entry - Topical Term FISH OILS   VITAMIN A   DRUG DOSAGE CALCULATIONS   PANGASIUS BUCHANANI   KANDUHITO   EXPERIMENTAL   FISH OILS   VITAMIN A   DRUG DOSAGE CALCULATIONS           Physical Location           Digital Copy Not Available          Add to Book Cart  |   Download MARC
