Antibacterial activity and phytochemical screening of ethanolic leaf, stem and flower extract of Aerva lanata

Abstract

Screening of phytochemicals provides the potentiality for serving several illnesses. The current investigation was carried out the antibacterial activity and phytochemical screening of ethanolic extract of leaf, flower and stem of Aerva lanata commonly known as Sir-upeelai through spectroscopic analysis. In this screening the major components are car-bohyrates, aminoacids, alkaloids, flavonoids, phenols, terpenoids and cocumarins. The antibacterial activity showed maximum sensitivity in leaf extract of Staphylococcus aureus (16mm). The FTIR spectroscopic analysis revealed that the functional groups were al-kene, alkyne, amines which showed major peaks. Based on antibacterial activity and functional group analysis, GC-MS was carried out in leaf extract of A. lanata. The current report indicated 27 bioactive compounds, in that Uridine is a major peak which showed antibacterial, anti-inflammatory, anti-diabetic, anti-cancerous activity etc.
