Tea polyphenols (TPPs) comprise preventive and therapeutic potentials against cancer, cardiovascular and neurological disorders. Chemical instability of TPP which leads to low bioavailability is the major constrain to its use as therapeutic agent. The authors prepared TPP encapsulated solid lipid nanoparticles (TPP‐SLNs) to increase its stability and bioefficacy. Comparison of Fourier transformed infrared spectra of unloaded SLN, free TPP and TPP‐SLN indicated encapsulation of TPP. Sustained release of TPP from TP‐SLN was observed. TPP‐SLN showed prolonged free radical scavenging activity compared with free TPP indicating protection of TPP. TPP‐SLN showed activation of Caspases‐9 and ‐3 cascades in breast cancer cell line (Michigan cancer foundation (MCF)‐7) at in vitro conditions. Biochemical parameters were altered in Ehrlich ascetic carcinoma (EAC) cell bearing mice compared with normal (uninduced) mice which were ameliorated significantly by oral feeding of TPP‐SLN. Oral administration (pre‐ and post‐treated) of TPP‐SLN in EAC bearing mice resulted in significant increase of plasma haemoglobin, glucose, superoxide dismutase and catalase when compared with EAC bearing control mice. Other biochemical parameters (cholesterol, bilirubin, triglyceride, urea, total protein, alanine aminotransferase, alkaline phosphatase and aspertate transaminase were significantly decreased on oral administration (pre‐ and post‐treated) of TPP‐SLN in EAC bearing mice.
