Abstract: Solanum torvum fruit widely used in traditional medicine of India and also in food preparation. Three different extracts such as water (WE), methanol (ME), and ethanol (EE) were used to evaluate their antioxidant and radical scavenging activity by different methods. All the assays results were compared with well‐known standard antioxidants. The IC50 values of assays were determined. The total phenolic and flavonoids content were found to be maximum in water and ethanol extracts, respectively. The electron quenching ability of fruit extract was assayed by DPPH and reducing power assays succeeding order were ME > EE > WE, respectively. Inhibition of membrane damage, was assayed interns of oxidative hemolysis and lipid peroxidation assays, among all WE extract shows 58.00% and 68.55 5% percentage of inhibition with 0.9 and 0.8 correlations (r2), respectively. Antioxidant and radical quenching efficiency were assayed by β‐carotene bleaching and hydroxyl radical scavenging method and results were compared with vitamin C and catechin. The in vitro free radical quenching and antioxidant results were well correlated with in vitro DNA protection assay. As analyzed by HPTLC gallic acid content is high in WE (1394 ± 25.0) and ME (598 ± 54.0) whereas ferulic acid is high in EE (32 ± 5.94) μg/g, respectively. This study indicate that S. torvum fruit is an excellent source of natural antioxidant and could be an effective nutritional food supplement, which interns will have therapeutic applications.
Practical Application: In siddha medicine on the traditional systems of India the, ripened fruits are used in the preparation of tonic named as a “sundaivattaral choornam” is used to improve the health and prevent several diseases. This study has given an experimental evidence that S. torvum fruit is an excellent source of natural antioxidants.

Flavonoids have well‐known antioxidant, anti‐inflammatory, and anti‐cancer activities. Isoflavone genistein is considered a potent antioxidant agent against oxidative stress. Although several mechanisms have been proposed, a clear antioxidant mechanism of genistein is still remain ... more
People can get oral cancers from UV (290‐400 nm) exposures. Besides high outdoor UV exposures, high indoor UV exposures to oral tissues can occur when consumers use UV‐emitting tanning devices to either tan or whiten their teeth. We compared the carcinogenic risks of skin to or ... more
A new study from the University of Southern California (USC) has found a link between recreational marijuana use and an increased risk of developing subtypes of testicular cancer that tend to carry a somewhat worse prognosis.

Researchers in the United States have developed a medical model for regenerating bladders using stem cells harvested from a patient’s own bone marrow. The research, published in STEM CELLS, is especially relevant for paediatric patients suffering from abnormally developed bladders, but also ... more
