摘　　要：UV-B辐射胁迫对地球生物的生命活动产生极大影响,其中药用植物次生代谢产物积累是对UV-B辐射胁迫的一种响应,其相关研究对提高药用植物次生代谢产物的产量、品质和合成效率,推动药用植物次生代谢产物的开发和利用,推进增加其药效技术的调控和创新具有参考意义。综述了UV-B辐射胁迫对药用植物次生代谢产物(萜类化合物、酚类化合物和含氮化合物)产量、质量及合成效率的影响,并深入地探讨了UV-B辐射胁迫对部分药用植物次生代谢产物的合成酶、合成途径及主要分子机制的影响。此外,还对UV-B辐射与其他因子复合作用作了概述。UV-B radiation stress significantly affects all life activities of earth organisms.The accumulation of secondary metabolites in medicinal plants is one of the response mechanism of UV-B radiation stress.The significance of relevant studies provide references for improving the yield,quality,and the synthetic efficiency of secondary metabolites in medicinal plants;and promoting its development and utilization,also enhancing its efficacy by relevant technical regulations and renovations.This study systematically investigated the impacts of the enhanced UV-B radiation on the yield,quality,synthetic efficiency of secondary metabolites produced by medicinal plants including terpene,phenolic,and nitrogen-containing-compound.Furthermore,the study explored a portion of secondary metabolites to discover the influences of enhanced UV-B radiation on their synthase,synthetic pathway,and the primary molecular mechanism.In addition,this study summarized the co-effects of UV-B radiation and other factors.
