| Abstract | ||||
| Holothuria atra is a marine invertebrate found in the tropical indo-pacific region. It contains potent bioactive compounds, which include lectin, steroidal saponins, and triterpene glycoside. The anti-inflammatory and antioxidant characteristics of Holothuria atra extract have been investigated in-vitro in this study. Ethyl acetate extract of H. atra was prepared by maceration methods, and then the phytochemical compositions were measured colorimetric and by using gas chromatography-mass spectrometry (GC-MS) Analysis. Hemolytic activity and anti-inflammatory properties of the extract were measured through cell culture protocol. The obtained results showed that the extract has a high phenol content (121.92±0.14 mg/g), and GC-MS analysis revealed that it contains, Oleic acid, 9-octadecenoic acid, methyl ester, and Octadecanoic acid. Moreover, antioxidant properties were determined by assessing 1, 1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, ferric reducing power, hydroxyl radical scavenging, and American Board of Thoracic Surgery (ABTS) scavenging activity. Furthermore, it is concluded that H. atra inhibited the stimulated Lipopolysaccharide (LPS) - Inducible nitric oxide synthase (iNOS) gene expression and protein expression by 6.17±0.01-fold change and Cyclooxygenase-2 (COX-2) gene expression by 4.70±0.05-fold change. The crude extract of H. atra could be considered a good anti-inflammatory agent. | ||||
