Application of jamun (Syzygium cumini Linn) seed extract on cotton fabric for antibacterial activity

Abstract

Attempts have been made to use jamun (Syzygium cumini Linn)seed extract on cotton fabric to evaluate its antibacterial activityagainst some Gram positive and Gram negative bacterial strains.Different concentrations of jamun extract (125, 250, 500 and 1000 mg/ mL) have been used and zone of inhibition (ZOI) is measured. Thefindings indicate that jamun seed has an antibacterial effect onbleached cotton fabric at different bacterial strain of Staphylococcusaureus (NCIM 2079) and Streptococcus agalactiae (NCIM 2401).The antibacterial potential of jamun seed powder is due to the richbioactive compounds. High inhibition percentage is obtained for 1000mg/mL seed extract and minimum for 125 mg/mL. Streptococcusagalactiae (77% strain) shows the maximum 24 mm ZOI andStaphylococcus aureus (55% strain) shows 18 mm ZOI.
