Introduction:
Trans-resveratrol is a bioactive polyphenol that has been widely studied for its antioxidant, anti-inflammatory, and chemoprotective properties. It holds promise in pharmaceutical and nutraceutical formulations but is limited by poor bioavailability and stability.
Methods:
This review synthesizes validated analytical methods for quantifying trans-resveratrol across various matrices. A comprehensive literature search (2000-2024) was conducted using PubMed, Scopus, and Google Scholar, focusing on RP-HPLC, HPTLC, GC, and UV spectroscopy. Method validation follows ICH guidelines. and nutraceutical formulations but is limited by poor bioavailability and stability.
Results:
Thirty-seven validated analytical methods were reviewed. RP-HPLC using C18 columns with acetonitrile-water mobile phases dominated the literature. The most sensitive technique identified was LC-MS/MS (LOD = 0.001 μg/mL), particularly effective in biological samples. Matrix types included wine, serum, and nanoparticle formulations. and nutraceutical formulations but is limited by poor bioavailability and stability.
Discussion:
RP-HPLC and LC-MS/MS have emerged as robust techniques for resveratrol quantification due to their sensitivity and specificity. Emerging tools like biosensors and UPLC offer rapid analysis with lower solvent consumption. Challenges such as isomerization, photodegradation, and matrix interferences necessitate stringent sample-handling protocols. and nutraceutical formulations but is limited by poor bioavailability and stability.
Conclusion:
Advanced chromatographic methods, especially RP-HPLC and LC-MS/MS, are essential for the reliable quantification of trans-resveratrol. Future research should focus on analytical standardization and the development of novel delivery systems to enhance resveratrol's pharmacokinetic profile.
