Two chemotypes of bergamot-mint: one rich in linalool accompanied by small quantity of linalyl acetate and the other rich in linalyl acetate accompanied by some amount of linalool are recognized. The linalool and linalyl acetate are used as a sedative and inflammatory medicine and are beneficial to mental and physical health as well as its widespread use in cosmetic and sterilization industries.
