α-Ocimene is a naturally occurring monoterpene found in essential oils from various plants, such as basil, mint, parsley, and citrus fruits. It is widely used in the fragrance and flavor industry due to its pleasant, fresh, herbal, green, and slightly citrusy aroma. As a common ingredient in perfumes, colognes, cosmetics, and scented products, it adds a natural note. In the food and beverage sector, it serves as a flavoring agent to enhance tastes in beverages, confectionery, and baked goods. α-Ocimene is also employed in insect repellent products for its efficacy against certain pests. In agriculture, it functions as a plant volatile organic compound that can attract pollinators or repel insects, supporting natural plant defense and pollination processes. Additionally, it plays a role in aromatherapy for its potential calming and uplifting effects. Emerging research highlights its antioxidant and anti-inflammatory properties, suggesting benefits in medical and health products. Its applications extend to studies in plant biology and ecology, aiding understanding of plant-insect interactions and signaling pathways.
