Abstract
Polyherbal formulation (Hibiscus sabdariffa, Zingiber officinale, Syzgium aromaticum and Cinnamomum tamala) has a wide range of applications, including culinary and medicinal uses. This study aimed to compare the vitamin contents of aqueous and hydroethanol extracts of polyherbal formulation shedding light on potential variations in nutritional value and bioavailability.
Polyherbs (Hibiscus sabdariffa, Zingiber officinale, Syzgium aromaticum and Cinnamomum tamala) were processed and subjected to two different extraction methods: aqueous and hydroethanol. The extracts were analyzed to determine the vitamins present and their concentrations which includes vitamin A, B complex components (B1, B2, B3, B6and B12) and C.
The results revealed notable differences in vitamin content between the two extraction methods. Hydroethanol extracts exhibited higher levels of vitamin C (62.133mg/kg) while Aqueous extracts contained higher concentrations of vitamin A (6.086mg/kg). Interestingly, both extraction methods yielded similar vitamin B complex profiles, indicating that this group of vitamins is less sensitive to the choice of solvent. From this study, both extracts contained appreciable amount of Vitamins.
