ABSRACT - [ Total Page(s): 1 ]In this study, the ascorbic acid levels in pineapple and banana were determined by titrimetric and spectrophotometric methods using oxalic acid and orthophosphoric acid as extracting solvents. The yield of ascorbic acid by titrimetric method ranged from 0.20 ± 0.02 mg/100g to 13.20 ± 0.05 mg/100g while spectrophotometric method ranged from 7.76 ± 4.7 mg/100g to 87.1 ± 6.3 mg/100g. Regardless of the extracting solvents and the estimation methods, the results revealed that ascorbic acid content was very high in pineapple while it was very low in banana. Comparison of the two estimati
