PHYTOCHEMICAL INVESTIGATION AND BIOLOGICAL PROFILING OF LIVISTONA CHINENSIS (CHINESE FAN PALM) SEEDS

Abstract

Livistona chinensis (L. chinensis) seeds have been used traditionally in treating various diseases. The qualitative analysis of the seeds extract showed the presence of different types of bioactive secondary metabolites like tannins, alkaloids, flavonoids, glycosides, steroids, anthraquinones, reducing sugars, emodins, terpenoids, phenols, and coumarics. The antioxidant activity was checked using DPPH free radical scavenging activity, showing a high antioxidant property. The GC-MS fatty acid composition of the seeds extract 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%). UHPLC-QTOF-MS analysis showed the presence of 25 non-volatile compounds present in the seeds extract including isobutyric acid, acetoin, 9- oxononanoic acid, piperidine, umbellic acid, furaneol, and ketopantolactone. The antimicrobial activity was shown only by the aqueous extract against the gram-negative bacteria (Klebsiella pneumonia) with an inhibition of 16.1 mm.Thus, the results from the current study reveals that the novel methanolic extract of L. chinensis have potential application in the pharmaceutical, cosmetics, and food industry.
