Opuntia ficus-indica
(L.) Mill. fruits known as prickly pear cactus are used in folk medicine
as well as food. In the present study it was
aimed to extract the volatile constituents of O. ficus-indica fruits by n-hexane. The volatiles were subsequently
analyzed by GC-FID and GC-MS, where a total of 14 compounds were identified.
The main components were characterized as hexadecanoic acid 39.4%, heptacosane 12.3%, and methyl linoleate 6.8%,
respectively. Further antimicrobial evaulation using a broth
microdilution assay (Clinical and Laboratory Standards Institute method) against
human pathogenic Staphylococcus aureus ATCC 6538, Enterococcus
faecalis ATCC 29212, Escherichia coli
NRLL B-3008, and Pseudomonas aeruginosa
ATCC 10145. The minimum non-reproductive concentrations were determined as MIC, where S. aureus showed the most potent
inhibition by 500 µg/mL.
