Seven phytochemicals were tested from the ethanolic extract of <em>Rosenvingea, </em>where four phytochemicals, namely steroid, glycosides, alkaloids, and tannins were present. However, ethanol extract exhibited low antioxidant activity compared to standard ascorbic acid as measured by DPPH-Free radical scavenging assay. In Brine Shrimp lethality bioassay, 50% ethanolic extract showed an LC<sub>50</sub> value of 10.88 mg/mL, whereas positive control (K<sub>2</sub>Cr<sub>2</sub>O<sub>7</sub>) showed LC<sub>50</sub> 59.97 µg/mL suggesting the less toxic property of the ethanolic extract. <em>In-vitro</em> antimicrobial activity of ethanolic extract of <em>Rosenvingea sp. </em>was investigated against gram-positive and gram-negative bacteria species (<em>Staphylococcus, Bacillus, Pseudomonas, Salmonella, and Klebsiella) </em>by agar disc diffusion method<em>. </em>The highest antibacterial activity was noticed against <em>Klebsiella pneumonia, Pseudomonas aeruginosa, Staphylococcus hominis</em> with a zone of inhibition of 5.00±1.00 mm, 3.66±0.57 mm, and 3.33±0.57 mm, respectively. This is the first study on <em>Rosenvingea sp.</em> from the Bay of Bengal, reporting its phytochemical, antioxidant, and antimicrobial potentiality. However, more study is required to elucidate its commercial viability in the food and medicine industries.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Phytochemical profiling, antioxidant potentiality and antibacterial activity of the ethanolic extracts of <i>Rosenvingea</i> sp. of Bay of Bengal","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Antibacterial, Antioxidant, DPPH, Cytotoxic, Phytochemical’s screening, Rosenvingea","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-11-30","DateCreate":"2021-11-30","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.3329/jbas.v45i1.54260"},"refs":null,"anarec":{"AnaID":347679,"PubliDate":2021,"Pagination":"59-71","XtraPublOfAnaID":null,"ISBN":null,"Volume":"45","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":347677,"SerRR":"Journal of Bangladesh Academy of Sciences.
