天然产物单萜类中除熟知精油中的普通单萜外,环烯醚单萜类(iridoids)则鲜为人知。自1963年Briggs等提出iridoids一词到七十年代才引起人们的重视和兴趣,这不仅由于这类单萜是许多民间药用植物的活性成分,而且还提供了萜类和生物碱结构间的联 In addition to common monoterpenes in essential oils, the natural product monoterpenoids are rarely known as iridoids. Since 1963, Briggs et al. introduced the word iridoids to the 1970s, which attracted people’s attention and interest. This is not only due to the fact that these monoterpenes are the active ingredients of many folk medicinal plants, but also provide the structure of the terpenes and alkaloids. Link
