“…The total lipid content ranged from 0.61% (G. catenata) to 1.47% (G. orientalis) in the present study (Table 1). A similar proportion of lipids have been reported in Gelidium pusilium (1.12%) and Hypnea chroides (1.48%), whereas Hypnea musciformis (0.28%) and Gracilariasalicornia (0.68%) were reported with fewer amount of total lipids (Siddique et al, 2013;Swarnam et al, 2021;Hossain et al, 2021).…”

“…This result resembles those reported for Kappaphycus alvarezii (79.7%), Turbinaria conoides (83.8%), Padina gymnospora (84.5%), Sargassum polycystum (83.5%), and Gracilaria verrucosa (85.45%) (Ahmad et al, 2012). In general, the red seaweeds consist of a high protein and dietary fibre content compared to green and brown algae (Hossain et al, 2021). The protein content of Grateloupia was exclusively high (Table 1), ranging from 12.40 to 16.00%.…”

“…The ash content represents total minerals composition ranging from 11.49 to 18.03% in Grateloupia (Table 1); the lowest and highest ash composition was reported from G. filicina and G. catenata, respectively. It was found to be less than those described for H. musciformis (22.56%) and G. pusilium (26.32%) (Hossain et al, 2021). Fibre is a polysaccharide and has a significant role in the digestive system of humans that reduces many physiological problems like constipation, colon disease, cardiovascular disease, obesity, etc.…”

“…The present study reported lesser carbohydrate contents in Grateloupia (Table 1), ranging from 5.17% (G. catenata) to 17.21% (G. indica). These values were significantly less when compared to other red algae such as Hypnea musciformis (20.6-37.46%), Gelidium pusilium (40.64-52.20%) (Siddique et al, 2013;Hossain et al, 2021).…”

Aim: The present study aimed to investigate the biochemical composition of five Grateloupia species and analysis of spatial variation in G. filicina and G. lithophila from the East and West coast of India. Methodology: Five Grateloupia species such as G. filicina, G. lithophila, G. catenata, G. orientalis and G. indica were collected from different states of India. Biochemical parameters like crude protein, total lipid, total ash, carbohydrates, total dietary fibre, chlorophyll, carotenoids, and total phenolic content were estimated to assess their nutritional values. Spatial variation for same parameters was also studied for G. filicina and G. lithophila. Results: It was observed that genus Grateloupia contained crude protein (12.4-16%), total lipid (0.61-1.47%), ash (11.49-18.03%), carbohydrate (5.17-17.21%), and total dietary fibre (54.08-66.16%) on a dry weight basis. Among all species, G. indica (16.00%) and G. filicina (15.48%) consisted of higher protein content. In contrast, G. orientalis (66.16%) and G. catenata (61.25%) had a maximum of total dietary fibre. The digestible energy obtained from Grateloupia was high, ranging from 85.93-141.29 kcal. Carotenoids (9.52-32.10 mg 100g-1) and total phenolic contents (TPC) (0.508-0.696 mg GAE g-1) represented the potential antioxidant activities of these Grateloupia species. Spatial variation in the biochemical composition of G. filicina and G. lithophila may be due to changes in the environmental factors. Interpretation: Biochemical compositions of these five species were similar to other edible Grateloupia species like G. turuturu and G. filicina. The results revealed that these species could be used for consumption purposes. Key words: Fibre, Grateloupia, Nutritional property, Phenols, Species, Spatial variation

“…This mild acidic fruit is mainly consumed fresh [6]. There are numerous scientific shreds of evidence that plant and its product, like-fruits, peel, leaves, and seeds contain different bioactive compounds which offer countless health benefits and protection against degenerative diseases [7][8][9][10][11].…”

The aim of this work was to optimize the extraction of antioxidative phenolic compounds from freeze-dried pulp, peel, and seed of Burmese grape using response surface methodology (RSM) with the target to maximize TPC, DPPH, and FRAP. Solvent (ethanol) concentration (%), temperature (°C), and time (min) were taken as independent variables by factorial screening for the extraction procedure. After extraction, the antioxidant activity of all samples was determined employing 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, total phenolic compounds (TPCs), and ferric reducing antioxidant power (FRAP) assay. The experiment's optimum conditions were 80% solvent concentration, 69.01 °C temperature, and 30 min for pulp. The optimum extraction conditions were found at 80 °C for 29.39-min incubation time using 52.12% concentrated solvent for seed. For peel, the solvent concentration of 41.62% was found optimum when the temperature of 50 °C and 30-min incubation time were used. The actual values of TPC, FRAP, and DPPH for freeze-dried pulp, peel, and seed extracts were close to the predicted values, which confirms the models' validity. The analysis of variance (ANOVA) showed that the models were significant for TPC, DPPH, and FRAP values of peel, pulp, and seed at different levels (p < 0.001 to p < 0.05). The composite desirability of pulp, seed, and peel were 0.94, 0.98, and 0.85, respectively, which suggests that the developed model could be effectively used for antioxidants' extraction from freeze-dried pulp, peel, and seed of Burmese grape.
