Total phenolic, flavonoids and tannin content of various extracts from Pyrus communis fruit

Abstract

The pyrus communis commonly known as Pear fruit having numerous pharmacological properties. Natural bioactive
compounds like phenols, tannin and flavonoids are the important secondary metabolites in plant possess wide range
biological action and this will supported with scientific studies on these metabolite from pear fruit. To maximize these agents
in the extract different solvents viz. chloroform, ethyl acetate, ethanol and aqueous are used for the extraction procedure.
Current study was aimed to determine the levels of total phenolic, flavonoids and tannin contents. Observations suggested
that ethyl acetate and ethanol extracts has significantly high (P<0.001) concentration of flavonoids, phenolic and tannin
contents as compared to aqueous and chloroform extracts. Therefore, ethyl acetate and ethanol extracts of pyrus communis
has greater potential to produce more beneficial effects in biological system as compared to aqueous and chloroform extracts.
