植物产生的光毒化学物质已经在许多背景下进行了研究，最著名的是作为哺乳动物和昆虫食草动物的保护剂。虽然这两类食草动物对植物光毒素的反应有共性，但也有差异。虽然已经证明了更大范围的化学类别显示出对昆虫的光毒性，但关于哺乳动物的光毒性的症状和作用机制的信息要多得多。这些共性包括摄取后行为的改变，特别是畏光，接触或摄取后体壁完整性的破坏，以及摄取后的代谢解毒，在涉及细胞色素P450单加氧酶的呋喃香豆素的情况下。在昆虫中尚不存在光毒素对感官(特别是视觉)系统的影响，以及由叶绿素代谢异常引起的光毒性。为了更好地理解光毒素介导的植物对昆虫和哺乳动物的防御的生态学意义，有必要进行更多以自然联系为中心的研究。(C)1995年Wiley-Liss公司
Phototoxic chemicals produced by plants have been studied in a number of contexts, most notably as protective agents against mammalian and insect herbivores. Although there are commonalities in the responses of these two groups of herbivores to plant phototoxins, there are differences as well. Whereas a greater range of chemical classes has been demonstrated to display phototoxicity against insects, considerably more information is available on symptomology of phototoxicity and mechanisms of action in mammals. The commonalities include alterations in behavior following ingestion, notably photophobia, disruption of integumentary integrity following contact or ingestion, and metabolic detoxification following ingestion, in the case of furanocoumarins involving cytochrome P450 monooxygenases. Not yet known to exist in insects are phototoxin-mediated effects on sensory (particularly visual) systems and phototoxicity resulting from abnormal chlorophyll metabolism. in order to gain greater understanding of the ecological significance of phototoxin-mediated plant defense against both insects and mammals, there is a need for more studies centered on natural associations.
