Abstract

Seaweeds contain a broad range of vitamins, particularly water-soluble vitamins. The objective of this study was to measure the levels of vitamin C and vitamin B6 in seaweed samples by acidic and enzymatic hydrolysis, followed by reverse-phase high-performance liquid chromatography (RP-HPLC) analysis using a UV detector. Vitamin C and vitamin B6 contents ranged from 1.62 to 48.28 mg/100 g and 3.54 to 22.24 mg/100 g, respectively. Sargassum sp. collected from Teknaf showed the highest vitamin C content, while Gracilaria sp. contained the highest level of vitamin B6. The vitamin levels varied depending on the seaweed species. However, this study revealed that seaweed can be a good source of vitamin C and vitamin B6. Therefore, it is possible to conclude that this seaweed has the potential to serve as an alternative source of vitamins for food security in Bangladesh.
