摘　　要：次生代谢产物的积累是决定中药材品质的关键因素,在药用植物由野生走向人工栽培的过程中,药效成分下降和质量不稳定的问题日益显现。紫外线B(Ultraviolet radiation B,UV-B)照射能够诱导植物内源性保护物质产生,进而改变植物次生代谢产物的合成。因此,研究UV-B如何影响药用植物次生代谢产物的积累及作用机制是当下热点之一。本文基于UV-B照射影响药用植物的生长发育、生理生化、次生代谢物积累和植物胁迫耐受性诱导等方面的最新研究报道,系统总结了药用植物对UV-B辐射的应答策略,以及UV-B辐射诱发的生物学效应,探讨了UV-B在刺激药用植物次生代谢产物合成及增强植物逆境胁迫抗性中的应用,指出当前研究中存在的挑战与不足,并对该领域的未来发展提出了设想,旨在为UV-B辐射在提升药用植物次生代谢产物积累及增强逆境耐受性的应用实践提供理论支撑。The accumulation of secondary metabolites is essential for determining the quality of traditional Chinese medicinal materials.However,as medicinal plants transition from wild growth to artificial cultivation,issues such as reduced active components and inconsistent quality have emerged.Ultraviolet radiation B(UV-B)radiation can stimulate the production of endogenous protective substances in plants,thereby influencing the synthesis of secondary metabolites.Understanding the effects of UV-B on secondary metabolite accumulation of secondary metabolites in medicinal plants,along with the associated mechanisms,has become a significant research focus.This review systematically summarized the response strategies of medicinal plants to UV-B radiation,highliting its effects on the growth,development,physiology,biochemistry,secondary metabolite accumulation,and stress tolerance induction.Furthermore,the potential applications of UV-B radiation in enhancing secondary metabolite synthesis and improving plant stress resistance are explored.Current research challenges and limitations are also discussed,offering insights for future advancements in this field.This review aims to provide a theoretical foundation for the practical application of UV-B irradiation technology in boosting secondary metabolite content and stress tolerance in medicinal plants.
