In the present work, vitamin C (ascorbic acid) content of some fruits; guava, kiwi, orange and lemon, and vegetables; green pepper, red pepper, greenhouse-growing pepper, tomato and parsley was determined by means of a titration method. It was found that ascorbic acid content of fruits was highest in guava (217.32 mg/100g) and lowest in lemon (58.12 mg/100g); and in vegetables, it was highest in green pepper (123.94 mg/100g) and lowest in green pepper grown in greenhouse (24.12 mg/100g). These observations may serve as guidance on selection of fruits and vegetables that can be consumed to meet the daily requirements of vitamin C.
