Nanoliposome ‐loaded phenolics from Salvia leriifolia Benth and its anticancer effects against induced colorectal cancer in mice

The objective of this study is to assess the therapeutic potential of phenolic-rich fraction encapsulated nanoliposome (PRF-NLs) ofSalvia leriifolia Benth in the treatment of colon cancer in mice. Initially, the phenolic-rich fraction (PRF) was extracted and then encapsulated into nanoliposomes. The physicochemical properties of the nanoliposomes were evaluated using dynamic light scattering, zeta potential, and field emission scanning electron microscopy. Subsequently, 24 mice with HT-29 colon cancer cells were divided into three groups, and the anticancer effects of PRF-NLs were measured. The results showed that the ethyl acetate fraction ofS. leriifolia was the highest PRF containing 14.27 ± 2.39 mg (gallic acid) GA/g DW (dry weight), and the PRF successfully loaded into the nanoliposome structure resulted in the synthesis of nanoliposomes with a nanometer size and spherical shape and homogenous dispersion. Some of the abundant bioactive phenolic compounds in the nanoliposome-loaded PRF are salicylic acid and naringin. The average daily weight gain and food intake, and changes in the expression of caspase 3, Bax (Bcl-2 associated X-protein), and Bcl2 (B-cell lymphoma 2), inducible nitric oxide synthase genes, were observed in the mice group induced colorectal cancer cells. At a dose of 100 mg TPC (total phenolic content)/kg BW/day, the nonencapsulated PRF dietary addition improved these parameters; however, the potential shown by nanoliposome-encapsulated PRF than the n...
