| Rutin is a nontoxic bioactive agent that extensively exists in fruits and vegetables with several
therapeutic properties, essentially attributed to its effective anti-inflammatory and antioxidant actions.
Rutin possesses poor bioavailability and low aqueous solubility, limiting its therapeutic applications.
The expansion of nanoparticulate systems is one of the technical routes to enhance the solubility and
bioavailability of rutin. The present study aimed to examine the antimicrobial effects of rutin
nanocrystals (RNs). A minimum inhibitory concentration (MIC), biofilm, and attachment inhibitory
effects of RNs were evaluated for several bacterial strains compared with bulk rutin. It was shown that
the aqueous dispersion of RNs was much more effective than rutin against Pseudomonas aeruginosa,
Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, Streptococcus mutans, Klebsiella
pneumonia, and Acinetobacter baumannii. The results revealed that rutin's antimicrobial activity
improved by reducing particle size up to the nano-sized range in the MIC test. RNs and rutin didn't
show any biofilm inhibitory effect. |
