| Description |
Aqueous extract of the seaweed Turbinaria conoides was purified to obtain an oligofucan-enriched seaweed concentrate (OESC). Oligofucans isolated were characterized as two types with (→1)-fucose-(2,3-diSO3 −)-(1→4)-fucose-(2- SO3 −)-(1→3)-fucose-(2,3-diSO3 −)-(1→4)-fucose-(2-SO3 −, 3-OAc)-(4→) and (→1)- fucose-(3-SO3 −)-(1→4)-fucose-(2-SO3 −)-(1→4)-fucose-(3-SO3 −)-(1→4)-fucose-(2- SO3 −)-(4→) motifs. A 90-day accelerated shelf-life study (50°C) showed that OESC maintained its antioxidant properties (free radical scavenging, reducing, lipid peroxidation inhibition, and chelating activities) even after 30 days. In vitro COX-2 and 5-LOX inhibitory properties of OESC (67.2 and 95.2%, respectively) showed no significant variation even at the 30th day. OESC significantly mitigated the carrageenan-induced inflammation in rats at 0–2 h (59.7– 70.3%inhibition), which were greater compared to the synthetic NSAID aspirin. The safety of OESC has been assessed by acute (14 days) and subchronic (90 days) oral toxicity studies, which showed no toxicity-related significant changes in renal or hepatic function, hematological indices, and serum biochemical parameters in the OESC-treated Wistar rats. No histopathological alterations were observed in the vital organs of rats treated with OESC. LD50 and sub-chronic no-observed-adverse-effect level (NOAEL) for this concentrate were found to be > 5,000 and 2,000mg/kg BW, respectively. Hence, oligofucan- enriched seaweed concentrate is safe to consume without any adverse effects in the body. |
