Abstract:
Background: 5-fluorouracil and resveratrol are the two most effective anticancer drugs.
Combination therapy with these two drugs has shown promising results in cancer. The formulation
containing 5-fluorouracil and resveratrol has been prepared, but no analytical method is available in
the literature for their simultaneous estimation. However, several analytical methods are there for estimation
of either 5-fluorouracil or resveratrol alone. Therefore, the present article is designed for the
simultaneous estimation of 5-fluorouracil and resveratrol by HPLC and its application in the quantification
of the drugs present in the formulated nanostructured lipid carrier (NLC).
Methods: The method was developed using a C18 column (Purospher® STAR RP-18 endcapped (5
μm) Hibar® RT 250-4.6) with acetonitrile and water as the mobile phase (25:75 v/v) and estimated at
272 nm. The currently developed method was further validated by the ICH guideline Q2 (R1). Combinatorial
NLC of 5-fluorouracil and resveratrol was also prepared and characterized.
Results: The LOD and LOQ were 8.22 and 24.91 μg mL-1 and 6.58 and 19.93 μg mL-1, respectively.
The precision was under the acceptable limits of <2% RSD. The content of 5-fluorouracil and
resveratrol in NLC were found to be 99.452% and 96.421%, respectively.
Conclusion: The findings showed that the developed and validated method was simple, fast, costeffective,
and reproducible for the simultaneous estimation of both the drugs in the same formulation.
