Botanical and Phytochemical Evolution of Rosa sp. Essential Oils: Taxonomy, Diversity, Industrial and Medicinal Applications

The genus Rosa L., belongs to the Rosaceae family, and includes roughly 125–250 species and thousands of cultivars spread across temperate and subtropical zones of the Northern Hemisphere. Recent botanical research emphasized how the genetic makeup of these roses influences their production of secondary metabolites, particularly volatile organic compounds that form essential oils. These oils play key roles in plant ecology by mediating interactions with pollinators, herbivores, and pathogens, thereby supporting reproduction and survival, and also have commercial purposes for fragrance and pharmaceutical markets. The botanical characteristics of oil-bearing roses, including their complex taxonomy, evolutionary relationships, and varied ecological functions, offer an essential foundation for understanding plant adaptation. By examining how different species and cultivars are classified and related, researchers can trace patterns of genetic diversity that influence traits such as scent profile, stress tolerance, and disease resistance. Their ecological roles, including attracting specific pollinators, deterring herbivores, and interacting with soil microbes, further reveal how these species respond to changes in temperature, precipitation, and land use. At the same time, the market for aromatic plant extracts is shifting as consumers increasingly prefer natural, sustainable, and bioactive ingredients. Rosa essential oils, once mainly associated with perfumery, are currently assessed for high-value use in pharmaceuticals, cosmeceuticals, and agro-industry. With that knowledge, modern breeding programs and agricultural practices can be directed toward selecting and propagating varieties that maintain high essential oil quality while requiring fewer inputs. Understanding the botanical and ecological dimensions of oil-bearing roses supports both conservation of genetic resources and the sustainable enhancement of their economic value for fragrance, pharmaceutical, and agricultural markets.
