摘要

次生代谢产物是植物在初级代谢过程中合成的生物活性化合物，在发育过程中没有作用，但用于防御和其他特殊目的。这些次生代谢产物，如类黄酮、萜烯、生物碱、蒽醌和类胡萝卜素，存在于地衣黄原菌属中。这些地衣在Teloschitaceae科中被称为地衣化真菌，生长在岩石上并产生生物活性化合物。植物中的许多次生化合物都是由紫外（100-400nm）光谱诱导的。本综述展示了目前在秀丽隐杆黄原菌和parietina地衣中鉴定的生物活性化合物，它们受到不同量的UV-B光（280-320nm）的刺激，以及UV-B吸收化合物的生物化学。

UV-B absorbing and bioactive secondary compounds in lichens Xanthoria elegans and Xanthoria parietina: A review

Secondary metabolites are the bioactive compounds of plants which are synthesized during primary metabolism, have no role in the development process but are needed for defense and other special purposes. These secondary metabolites, such as flavonoids, terpenes, alkaloids, anthraquinones and carotenoids, are found in Xanthoria genus lichens. These lichens are known as lichenized fungi in the family Teloschistaceae, which grows on rock and produce bioactive compounds. A lot of secondary compounds in plants are induced by UV (100-400 nm) spectra. The present review showcases the present identified bioactive compounds in Xanthoria elegans and Xanthoria parietina lichens, which are stimulated by different amounts of UV-B light (280-320 nm), as well as the biochemistry of the UV-B absorbingcompounds.
