Asparagusic acid is a naturally occurring sulfur-containing compound primarily found in asparagus. It serves as a precursor to volatile sulfur metabolites, such as methanethiol and dimethyl sulfide, which are responsible for the characteristic sulfurous odor in urine following asparagus consumption. This compound has attracted interest for its potential biological activities. In agriculture, it is investigated as a natural biopesticide due to its antimicrobial and insect-repellent properties, providing an eco-friendly option against pests and pathogens. In health applications, studies highlight its antioxidant effects, which may help mitigate oxidative stress. Preliminary research also explores its anti-cancer potential by inhibiting certain cancer cell growth and its role in diabetes management through blood sugar regulation. Further research is required to validate and expand these applications.
