Publication date: January 2020Source: Biocatalysis and Agricultural Biotechnology, Volume 23Author(s): Mehrez E. El-Naggar, Rana A. Soliman, Osama M. Morsy, Mohamed S. Abdel-AzizAbstractThe utilization of natural resources for cotton fabrics treatments is very necessitous in order to reduce the chemicals that are used and also have a very great harm to humans and the environment. The literature studies describe the utilization of pepper horns in many different applications such as drugs and agricultural fields, etc.,. However, there is no information about the utilization of pepper horn extracts in its nanoemulsion form to be used as antimicrobial finishing agent for textile fabrics. Thus, the current research work aimed to compare the antimicrobial properties of pepper horns extract in two different forms; micro- and nanoemulsion. The powder was extracted with absolute ethyl alcohol and a reddish colored oily extract has been produced after evaporation using rotary evaporator. It has been found that the major constituents of the Capsicum extract are 9,12-octadecadienal (29.99%), linalyl acetate (18.38%), Z, Z-10,12-hexadecadien-1-ol acetate (14.65%), and 2-methyl-1,5-hexadiene-3-ol (3.75%). Different concentrations from this extract was directly loaded to cotton fabric discs to evaluate its antimicrobial activity and it was found that by decreasing the concentration the activity increased. The extract exhibited better antimicrobial activity against G + ve bacteria and Yeas...
