Resveratrol is a natural compound classified as a stilbenoid, which is a type of polyphenol or natural phenol. It is produced by several plants as a phytoalexin-a protective antibiotic substance synthesized in response to stress such as injury, fungal attack, or ultraviolet radiation

. Chemically, it is known as 3,5,4′-trihydroxy-trans-stilbene and exists mainly in two isomeric forms: trans- and cis-resveratrol

. This compound is found in the skin of red grapes, blueberries, raspberries, mulberries, peanuts, and red wine, with red wine containing significantly higher amounts due to fermentation with grape skins

. Plants produce resveratrol to defend against pathogens like bacteria and fungi

. Resveratrol is widely studied for its antioxidant properties, which help protect the body from damage caused by free radicals. It is believed to have several potential health benefits, including anticancer, cardioprotective, neuroprotective, anti-inflammatory, and immunomodulatory effects

. Despite these promising effects observed in laboratory and animal studies, there is currently no high-quality evidence that resveratrol supplements significantly improve human lifespan or treat diseases

. In summary, resveratrol is a plant-derived antioxidant compound with potential health benefits, primarily found in grape skins and red wine, acting as a natural defense molecule in plants and studied for its protective effects in humans
