Effects of salicylic acid (SA), H₂O₂, imidazole (IMD), catalase (CAT), dimethylthiourea (DMTU) and complex treatments on the production of Sal B and H₂O₂ in Salvia miltiorrhiza cell cultures. The concentrations for SA, H₂O₂, IMD, CAT and DMTU were 22 mg·L⁻¹, 10 mmol·L⁻¹, 100 μmol·L⁻¹, 100 U and 500 μmol·L⁻¹, respectively. SA was added to subcultured Salvia miltiorrhiza cells after 8 d culture, and both contents of H₂O₂ and Sal B were determined in the subsequent 8 h and 2 d, respectively, with three replications. Different lowercase letters represented significance at 0.05.
