Métabolisme Secondaire des plantes : Master I Biodiversité et Physiologie Végétale

Abstract

In recent years, medicinal plants have assumed a prominent role. This surge in popularity stems from a growing interest in natural substances across diverse sectors such as the food industry, cosmetology, and pharmaceuticals. Long used in traditional medicine, these plants derive their therapeutic properties from their chemical components. Whether involving primary or secondary metabolites, their efficacy relies either on specific molecules or on the synergy between their various constituents. Humans have always turned to the plant world to meet their needs—from providing food and decorating their surroundings to producing beverages and dyes. Among these resources, aromatic herbs and spices hold a place of distinction; used as condiments, they are key to culinary enjoyment and the richness of flavors. The use of botanical properties in cosmetology is a centuries-old tradition that is currently experiencing a major resurgence. Products designed to enhance physical appearance are increasingly incorporating substances of natural origin. Consequently, floral waters, macerations, and plant essences are enriching and adding complexity to the active ingredients found in modern cosmetics.
