Bioactivity of Ethanolic Extract of Borassus flabellifer Sprout Peel and Its Phytochemical Analysis: An In vitro Study.

Palmyra palm sprout skin was extracted using ethanol to test its antibacterial activity against isolated urinary tract infection (UTI) pathogenic bacteria. The extract demonstrated excellent inhibitory activity at the concentration of 500 µl/well. It was observed that all the isolated UTI-causing bacteria were highly resistant to selected commercially available antibiotics. The ethanol extract of the palmyra palm sprout skin showed excellent antioxidant, anti-inflammatory, antidiabetic, and antiproliferative activities. Before boiling the Panam kilangu, the sprout skin is usually peeled from it and thrown away as it is considered of no use. However, our study demonstrates a waste-to-wealth based alternative use for the palmyra palm sprout skin. Based on studies, these by-products could be used as a source of valuable bioactive compounds. It showed excellent inhibitory activity at the concentration of 500 µg/well against UTI bacteria. It also showed to possess various secondary metabolites, such as flavonoids, saponins, etc. Gas chromatography-mass spectrometer analysis revealed the presence of various bioactive metabolites.
