    Terpenes are the naturally occurring combination of carbon and hydrogen, whereas terpenoids are terpenes that have been modified through a drying and curing process (chemical modification), altering the oxygen content of the compound. term terpenoids also covers natural degradation products, such as ionones, and natural and syn-thetic derivatives, e.g., terpene alcohols, alde-hydes, ketones, acids, esters, epoxides, and hy- drogenation products. An overview of the most important basic structures demonstrates the structural variety of terpenes [8]. The compounds are normally known by their trivial names, as the systematic
