“…The reaction solution was incubated at 37 °C for 1 h. Then 3 mL of the reaction solution were mixed with 3 mL Griess reagent. After vigorous mixing with a vortex, the mixture was placed at room temperature for 15 min and the absorbance at 544 nm was recorded as A i ; A 0 was the absorbance of control group (water instead of sample solutions) [60,61]. …”

Four seaweed polysaccharides were extracted from Sarcodia ceylonensis, Ulva lactuca L., Gracilaria lemaneiformis, and Durvillaea antarctica, respectively, by microwave-assisted extraction. The effect of three significant variables (extraction time, extraction temperature, and the ratio of water to raw material) on the process for extracting polysaccharides was investigated, along with the optimization of the extraction using the response surface method (RSM) with a Box–Behnken design. The polysaccharide structure, monosaccharide composition, degree of sulfation, and molecular weight (MW) distribution were analyzed by infrared (IR) spectrometry, gas chromatography (GC), and high-performance gel permeation chromatography (HPGPC). IR spectrometry showed that Sarcodia ceylonensis polysaccharide (SCP), Ulva lactuca L. polysaccharide (ULLP), and Durvillaea antarctica polysaccharide (DAP) were all sulfated polysaccharides and, except Gracilaria lemaneiformis polysaccharide (GLP), all belong to β-pyranosidic polysaccharides. The average molecular weight (MW) of SCP, ULLP, GLP, and DAP was 466, 404, 591, and 482 kDa, respectively. The quantitative and comparative results with external standards indicated that the main monosaccharide in SCP and ULLP was mannose; and GLP and DAP were mainly composed of galactose and glucose, respectively. Then the in vitro antioxidant activity of all of the polysaccharides was evaluated using different assays—2,2–azino –bis (3-ethylbenzthiazoline-6- sulfonate) (ABTS), hydroxyl radical, nitrite scavenging capacity, and reducing power—and the relationship between their antioxidant activity and chemical characteristics were also examined. ULLP presented the highest ABTS radical scavenging activity; ULLP, SCP and DAP also showed a strong effect on the ABTS radical scavenging activity. SCP and ULLP exhibited excellent hydroxyl radical scavenging activities, about 83.33% ± 2.31% and 80.07% ± 2.17%, respectively, at 4 mg/mL. The reducing power of DAP was relatively more pronounced than that of the three other polysaccharides. However, the nitrite scavenging activities of the four seaweed polysaccharides were weaker than other antioxidant activity (ABTS), hydroxyl radical scavenging capacity, and reducing power. In addition, GLP exhibited lower activities than the other three samples in all of the tests for the antioxidant activity.

“…32 Phenolic compounds, sodium ascorbate, and erythorbate have antioxidant ability, as well as nitrite scavenging activity. 33 Kim et al 34 also reported the positive relationship between total phenolic content and nitrite scavenging activity in various beverages. In the present study, we confirmed the antioxidant and nitrite scavenging activities of ascorbic acid and sodium erythorbate, whereas these effects were observed from T2 (0.2% CBP addition) at the late storage weeks.…”

“…Leafy and root vegetables contain large quantities of nitrite that is extremely toxic. The excessive ingestion of nitrites leads to negative effects like methemoglobinemia by the oxidation of hemoglobin (Kim et al, 2014). In this study the extract showed excellent scavenging of nitric oxide radicals.…”

Background: Ethnic medication systems have been used extensively by humans since their origin. Now a day, in the developing countries these systems are being used due to their effectiveness and affordability. Especially inhabitants of rural areas still rely on these systems as first line of treatment against diseased conditions. Till now, majority of medicines is derived from the natural origin particularly plants owing to their little side effects and cost effectiveness. Materials and Methods:In the present work, we evaluated antibacterial and antioxidant activity of methanolic extract of Bombax ceiba stem bark. Total phenolic and flavonoid contents were also assessed in the extract. The antioxidant capacity was determined by DPPH, Nitric Oxide scavenging and reducing power activity. For antibacterial activity, Gram-negative (Escherichia coli, Pseudomonas aeruginosa and Salmonella typhi) and Gram-positive bacteria (Bacillus subtilis, Staphylococcus aureus) were used. Results: Phenolic content was 133.21±1.56 µg GAE/mg of extract while Flavonoid content was 997.93±2.14 µg QE/mg. Plant extract demonstrated strong antiradical activity with EC 50 18.78 ± 0.69 and 23.62 ± 1.99µg/ml for Nitric Oxide and DPPH assay respectively while EC 50 in case of reducing power activity was 139.4 ± 0.98µg/ml. Plant extract displayed inhibitory effect against microbial growth with S. typhi as the most resistant strain and Staphylococcus aureus the most sensitive one. Conclusion: This study revealed that Bombax ceiba of local origin has broad spectrum antibacterial activity and it can also provide defense against oxidative stress.
