The low yield and active ingredient content of medicinal plants is always a challenge. However, nanotechnology offers new tools for enhancing the biomass and metabolism of medicinal plants. In the present study, the effects of two nanomaterials (NMs) on the growth, photosynthesis, antioxidant system, mineral homeostasis, C/N accumulation, and content of active ingredients of Isatis indigotica (BLG) were investigated. BLG was grown in soil supplemented with 10–250 mg kg−1 of multi-walled carbon nanotubes (CNTs) or iron oxide nanoparticles (Fe2O3 NPs) for 60 days in a greenhouse. The results showed that a low concentration (10 mg kg−1) of Fe2O3 NPs promoted the growth of BLG, while the opposite trend was observed in the CNT treatment. Fe2O3 NPs at 10 mg kg−1 effectively increased the shoot length and biomass by 21% and 14%, respectively. Notably, the Fe2O3 NPs could also effectively enhance the officinal ingredient content of BLG by regulating the antioxidant system, mineral element homeostasis, and carbon and nitrogen synthesis. Fe2O3 NPs at 10 mg kg−1 increased the flavonoids, soluble sugars, and total protein content of BLG roots by 55%, 124%, and 59%, respectively. In conclusion, our results suggest that the Fe2O3 NPs can be used as a bio-fortifier to enhance the yield and officinal quality of BLG.

铁纳米粒子与碳纳米管增加中药板蓝根活性成分的比较研究
药用植物的低产量和活性成分含量一直是一个挑战。然而，纳米技术为提高药用植物的生物量和新陈代谢提供了新的工具。在本研究中，研究了两种纳米材料（NMs）对板蓝根（BLG）生长、光合作用、抗氧化系统、矿物质稳态、C/N积累和活性成分含量的影响。BLG 在添加了 10-250 mg kg -1多壁碳纳米管 (CNT) 或氧化铁纳米粒子 (Fe 2 O 3 NPs) 的土壤中在温室中生长 60 天。结果表明，低浓度（10 mg kg -1）的 Fe 2 O 3NPs促进了BLG的生长，而在CNT处理中观察到相反的趋势。10 mg kg -1的Fe 2 O 3 NPs 分别有效地增加了21% 和14% 的枝条长度和生物量。值得注意的是，Fe 2 O 3 NPs还可以通过调节抗氧化系统、矿物质元素稳态和碳氮合成来有效提高BLG的药用成分含量。10 mg kg -1的Fe 2 O 3 NPs使BLG 根的类黄酮、可溶性糖和总蛋白质含量分别增加了55%、124% 和59%。总之，我们的结果表明 Fe 2 O 3NPs 可用作生物强化剂以提高 BLG 的产量和药用品质。
