Summary, etc. <p>The seeds of<em> Livistona chinensis </em>(Jacq.) R.Br. ex Mart.<em> </em>(Family: Arecaceae) plant traditionally find application in the treatment of various diseases. Therefore, in the present study, phytochemical screening and biological profiling of <em>Livistona chinensis</em> seed extracts were conducted. The bioactive components were analysed using GC-MS and UHPLC-QTOF-MS and the fatty acid composition was determined using FAME analysis. GC-MS analysis results indicated the presence of oleic acid (35.71%) and palmitic acid (30.7%) as major components in the seed extract prepared in n-hexane. UHPLC-QTOF-MS analysis revealed the presence of 25 secondary metabolites, including isobutyric acid, acetoin, 9-oxononanoic acid, piperidine, umbellic acid, furaneol, and ketopantolactone in the methanolic extract of seeds. FAME analysis results suggested the presence of oleic acid (18.44%), lauric acid (11.66%), linoleic acid (11.30%), linolenic acid (10.20%), and palmitic acid (9.96%) in abundance. In biological profiling, <em>Livistona chinensis</em> seed extracts were subjected to <em>in vitro</em> antimicrobial, and antioxidant activity. The aqueous extract exclusively showed antimicrobial activity, and exhibited inhibition zone of 16.1 mm only against gram-negative bacteria (<em>Klebsiella pneumonia</em>). The methanolic extract demonstrated maximum antioxidant activity, at sample concentration of 200 µL. These findings suggest that <br /> <em>Livistona chinensis</em> seeds might be a potential source of bioactive metabolites, antimicrobial agents, and antioxidant agents that may be utilised in pharmaceutical, cosmetics, and food industries.</p>
