In addition, several types of terpenoids or terpenes ([C.sub.10][H.sub.16]), such as diterpenes ([C.sub.20]), triterpenes ([C.sub.30]), tetraterpenes ([C.sub.40]), hemiterpenes ([C.sub.5]), and sesquiterpenes ([C.sub.15]), have also effective antifungal activity [16].
They are classified as hemiterpenes (C5), monoterpenes (C10), sesquiterpenes (C15), diterpenes (C20), sesterpenes (C25), triterpenes (C30), tetraterpenes (C40), and polyterpenes (>C40).
Many of them are volatile, as hemiterpenes ([C.sub.5]), monoterpenes ([C.sub.10]), sesquiterpenes ([C.sub.15]), and even some diterpenes ([C.sub.20]).
