Background: Natural sources like plants, vegetables, and fruits contain vast micro and macro nutrients that are useful for livelihood and also act as a medicine for various health conditions. Brassica vegetable naturally contains high antioxidant property which aids in removing free radicals caused by organelles during cellular process. The study aims at preparing Brassica oleracea extracts using a range of polar and non-polar solvents and to evaluate its phytochemical, antioxidant and cytotoxicity properties. Methods: Brassica oleracea was extracted using hexane, ethyl acetate and ethanol. All the extracts were subjected to phytochemical analysis and antioxidant activity was performed using DPPH method. The antiproliferative activity was perfomed on THP-1 cells by MTT assay. The extract showing maximum activity was then characterized using FTIR and GCMS. Results: The extract study infers positive results for major secondary metabolites (alkaloids, glycosides, proteins, phenols, tannins, steroids, flavonoids, terpenoids and diterpenes) and negative for quinones and coumarins. DPPH radical scavenging assay showed high antioxidant activity for ethanol extracts 45-91\% at 5μg/mL followed by ethyl acetate (37\%-80\%) and hexane extract (23\%-73\%). The anti-proliferative activity in THP-1 cells, revealed that the ethanolic extract significantly decreases cell viability relative to hexane and ethyl acetate extracts, indicating its potential as a natural anticancer drug. Conclusion: Cytotoxicity studies further demonstrated a concentration dependent effect on cell viability, indicating its potential bioactivity. The structural analysis performed with FTIR and GC-MS revealed important functional groups and bioactive compounds that could play a role in these effects

The presence of ROS is associated with aging, which is damage caused by free radical reactions. ROS causes oxidation of low density lipoprotein (LDL), which builds up in plaque and contributes to inflammation. With aldehyde secondary products of lipid peroxidation such as Malondialdehyde (MDA), lipoxygenase, and xanthine oxidase as markers of oxidative stress, oxidized LDL causes endothelial dysfunction and cell apoptosis. The antioxidant 1,1 diphenyl-2-picrylhydrazyl (DPPH) sericin from Bombyx mori was tested in silico and in vitro in this study. The Bombyx mori peptide sequences QAYADYHSDPNGGSA (SP4) and ASSSFDASSA (SP7) had lower Gibbs energy for lipooxygenase (LOX) than native ligands, with values of -23.1044, -21.0056, and -10.3275 kcal/mol, respectively. hydrogen bonding to Gln289, Asp293, and Gly569. While ASSSFDASSA (SP7) has a higher Gibbs energy for xanthine oxidase (XOX), SEASSSTQATTVS (SP 5) has a lower Gibbs energy with values of -20.1839, -17.8952, and -11.8921 kcal/mol, respectively. While the cavity binding of the xanthine oxidase peptide binding SP5 and SP7 is located at the Glu802, Asp872, and Ser876 binding sites, the DPPH test confirmed in vitro that the 10\% sericin Gel had an IC50 of 19.7394 ppm compared to 3.71 ppm ascorbic acid. The findings of the preceding study demonstrate that sericin, as an antioxidant, is one of the candidates for antiaging.
