BIOACTIVE POTENTIAL OF HIBISCUS ROSA SINENSIS AND JASMINUM SAMBAC EXTRACTS AGAINST FOOD BORNE PATHOGENS

Foodborne diseases (FBD) are a serious issue that affect not only human health but also has an impact on the global economy. They remain a persistent problem due to the continuing changes in global food trade trends, dietary patterns, food manufacturing, and the emergence of foodborne microbes in the food chain. In Pakistan, where meat is considered as an essential component of our meal but due to high nutrient concentration levels, high water activity, minerals and vitamins, and other growth factors such as pH microbes thrive in it. The extensive use of antibiotics has resulted in antimicrobial resistant (AMR) bacteria in E. coli, Salmonella, Campylobacter and Listeria spp. Traditional medicinal practices especially the use of plant extracts continue to play a crucial role in addressing basic healthcare needs in underdeveloped countries. The purpose of our study was to check the antibacterial potential of Jasminum sambac (Jasmine) and Hibiscus rosa sinensis (China rose) extracts against foodborne pathogens i.e. E. coli, Salmonella and Campylobacter. The hot and cold extracts were prepared using ethanol and distilled water and the antibacterial activity were observed by agar well diffusion method. The minimum inhibitory concentration (MIC) was also carried out the plant extracts gave MIC values of 6 and 12 µg/ml for E. coli and Salmonella respectively. The minimum bactericidal concentration (MBC) showed that ethanol extracts of both plants possessed bactericidal activity. Our study indicates that the native plants of Pakistan have significant bioactivity against foodborne pathogens.
