The nutraceutical value, and physicochemical profile as well as anti-inflammatory activity potential of Odonthalia floccose and Odonthalia dentata (red macroalgae) dry biomass were investigated in this study. Proximate composition study results revealed that the dry biomass of O. floccose and O. dentae were found to be as ash: 9.11 & 8.7 g 100 g−1, moisture: 8.24 & 8.1 g 100 g−1, total fat: 6.9 & 7.2 g 100 g−1, protein: 24.52 & 25.6 g 100 g−1, and total carbohydrate/polysaccharides: 53.84 & 48.85 g 100 g−1 of dry weight biomass respectively. Both algae biomass contain considerable quantity of minerals (Fe, Cu, Mg, and Zn). Furthermore, the major saturated fatty acids (6.24 & 5.82 g FAME 100 g−1 of total fat of O. floccose and O. dentate) (ΣFAs) present in the test algae were stearic acid, palmitic acid, and margaric acids. O. floccose and O. dentata also contain remarkable protein composition profile that compiled with considerable quantity of essential and non-essential amino acids. The vitamins such as vitamin A, B1, B2, B3, B6, B9, C, and E of O. floccose and O. dentate biomass were also identified at sufficient quantity level. The swelling capacity (SWC), water holding capacity (WHC), and oil holding capacity (OHC) properties of O. floccose and O. dentate at various temperature conditions (25 and 37 ᵒC) were found to be 8.11 & 7.02 mL g−1 and 8.95 & 7.55 mL g−1, 5.1 & 4.87 and 4.8 & 4.1 mL g−1, as well as 2.11 & 1.81 and 1.96 & 1.89 mL g−1 respectively. Among these two marine red macroalgae samples, the O. dentate showed better anti-inflammatory activity than O. floccose at 150 μg mL−1 dosage. Thus, this O. floccose and O. dentate biomass can be considerable as nutritional supplement and pharmaceutical product development related research. •O. floccose and O. dentae possesses fine proximate parameters.•Both these test red algae contain considerable quantity of minerals.•Stearic acid, palmitic acid, & margaric acids found as major saturated fatty acids.•Vitamin A, B, C, & E well available in O. floccose and O. dentate biomass.•O. dentate showed better anti-inflammatory activity than O. floccose at 150 μg mL−1
