Abstract

Dua kaedah titratan redoks, iaitu, kaedah iodometric dan kaedah DCP/DCPIP telah digunakan dalam analisis kandungan vitamin C dalam tiga produk vitamin C. Hasil kajian menunjukkan kandungan vitamin C dalam jenama Flavettes, Redoxon dan Ceelin adalah masing-masing 493.3±6.7 mg/pil, 992.1±7.9 mg/pi/ dan 99.8±0.2 mg/5 mL sirap bagi analisis titratan iodomelrik dan masing-masing 495.6±4.4 mg/pil, 945.8±54.2 mg/pil dan 96.8±3.2 mg/5 mL sirap bagi analisis tilratan DCP/DCPIP. Nilai yang diperolehi adalah hampir sama FA) ralat relatif <5%) dengan nilai yang dilaporkan iaitu masing-masing 500 mg/pil, 1000 mg/pil dan 100 mg/5 mL sirap.
