Livistona chinensis (Family: Arecaceae) seeds have been used traditionally in treating various diseases. In the present study, we evaluated the phytochemicals screening and biological profiling of Livistona chinensis seeds extract. The bioactive components were analyzed by GC-MS and UHPLC-QTOF-MS. The fatty acid composition was analyzed by FAME analysis. GC-MS analysis showed the presence of oleic acid (35.71%) and palmitic acid (30.7%) as the major component in the n-hexane extract of seeds. UHPLC-QTOF-MS analysis showed the presence of 25 secondary metabolites in the methanolic extract of seeds including isobutyric acid, acetoin, 9-oxononanoic acid, piperidine, umbellic acid, furaneol, and ketopantolactone. The FAME analysis showed majorly 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 biological profiling, Livistona chinensis seeds extract was analyzed for in vitro antimicrobial, and antioxidant activity. The methanolic extract showed the maximum antioxidant activity at 200 µL sample concentration. The antimicrobial activity was shown only by the aqueous extract against the gram-negative bacteria (Klebsiella pneumonia) with inhibition of 16.1 mm. These findings suggest that Livistona chinensis seeds might be a potential source of bioactive metabolites, antimicrobial agents, and antioxidant agents that can be utilized in pharmaceutical, cosmetics, and food industries.
