Assessment of total phenolic content and antimicrobial activity of plants leaves extract

Abstract

Novel finishes of high added value for apparel fabrics are also greatly appreciated by a more discerning and demanding consumer market. Antimicrobial textile with improved functionality finds a use in variety of applications such as health and hygiene products. Now plant resources are getting attention of manufacturer, academician and researchers due to its ecofriendly nature and versatile properties such as antibacterial and ultra-violet protection which can be used for imparting finishing to textiles. In the present study the efforts were made to impart antibacterial finish to the cotton textile using natural resources. Here the leaves of ten plant sources viz. neem, safeda, aonla, sagun, nimboo, jamun, curry patta, peepal, mehandi and bael were taken on the review basis and their yield count in ethanol and methanol extract, Total Phenolic Content (TPC) and antibacterial properties against S. aureus (gram +) and E. coli (gram -) bacteria and antifungal properties against aspergillus niger fungus were studied using qualitative test method. It was found that jamun leaves showed the highest yield in aqueous extract whereas as aonla showed the highest yield in ethanolic extraction medium. The Total Phenolic Content (TPC) was found highest in neem leaves in both medium of extraction i.e. aqueous and ethanolic. It was also noticed that ethanolic medium of extract showed maximum resistance against bacterial as well as fungal growth as compared to aqueous extraction medium. In etanolic medium of extraction, the safeda leaves showed the highest zone of inhibition i.e. 23 and 20 mm against S. aureus (gram +) and E. coli (gram -) bacteria, respectively followed by bael leaves (20 mm each) where as neem leaves showed the highest zone of inhibition i.e.11 mm against Aspergillus niger fungus in ethanolic medium of extraction.
