rac-Falcarinol (CAS 4117-12-8)

rac-Falcarinol, a natural polyacetylene compound found in several vegetables such as carrots, celery, and parsley, is recognized for its intriguing biologically active properties, particularly in agricultural and food science research. As an isomer of the naturally occurring falcarinol, rac-falcarinol exhibits activities that influence plant growth and health, serving both as a plant defense molecule against pests and a promoter of certain beneficial plant responses. In its action, rac-falcarinol interferes with fungal and bacterial cell wall synthesis by targeting and disrupting lipid components within cell membranes, thereby inhibiting the growth of these pathogens. This mechanism is crucial for understanding its role in natural plant defense systems and its potential application in developing natural pesticide alternatives. Furthermore, research has explored its impact on plant physiology, including studies on its ability to modulate plant hormonal pathways and stress responses, which can enhance overall plant resilience and productivity. In the context of food science, rac-falcarinol has been investigated for its effect on the nutritional quality of crops and its stability during food processing, aiming to maximize the health benefits derived from falcarinol-rich foods while assessing the implications of its consumption on human health in non-medical settings.
