Terpenoids, sometimes called isoprenoids, are the most abundant and structurally diverse natural compounds found in a wide range of plants. Several in vitro, preclinical, and clinical studies have established that this class of chemicals has a diverse set of pharmacological activities. The wide range of terpenoid structures and activities has sparked greater interest in their commercial application, resulting in the registration of some with wellestablished medicinal applications as pharmaceuticals on the market. This chapter examines the classification of terpenoids, including brief descriptions of each group, extraction methods, chemical identification, and their wide range of pharmacological effects and medicinal applications.
