The percentage of ascorbic acid content in vitamin C syrups containing 100mg/5ml showed that samples (1,2,3 and 7) having (68.37%,54.10%, 52.10%, and 74.00%) were below 95-105 recommended by British pharmacopeia limit. While for A samples (4, 5 and 6)have percentage ascorbic acid content of (95.00%, 95.10% and 96.00% )respectively and were within the normal ranges.
