Terpenoids are the largest group of plant specialized (secondary) metabolites. These naturally occurring chemical compounds are highly diverse in chemical structure. Although there have been many excellent studies of terpenoids, most have focused on compounds built solely of isoprene units. Plants, however, also contain many 'atypical' terpenoids, such as glycosylated volatile terpenes and composite-type terpenoids, the latter of which are synthesized by the coupling of isoprene units on aromatic compounds. This mini review describes these 'hidden' terpenoids, providing an overview of their biosynthesis, localization, and biological and ecological activities.
萜类化合物是植物中最大的一类特殊（次生）代谢产物。这些天然存在的化学化合物在化学结构上具有高度的多样性。尽管已经有许多关于萜类化合物的优秀研究，但大多数研究都集中在仅由异戊二烯单元构成的化合物上。然而，植物中也含有许多“非典型”的萜类化合物，如糖基化挥发性萜类化合物和复合型萜类化合物，后者是由异戊二烯单元与芳香族化合物偶联合成的。这篇简要综述描述了这些“隐藏”的萜类化合物，概述了它们的生物合成、定位以及生物和生态活性。
