ObjectiveTo identify the optimal harvesting age, timing, and drying method for Paeoniae Radix Rubra in Tongliao, Inner Mongolia, China.MethodsThe plant traits, biomass, and contents of eight pharmacodynamic substances were measured in 3-, 4-, and 5-year-old cultivated Paeonia lactiflora Pall. plants. 5 drying methods were applied to the roots of 4-year-old root. The bioactive components were quantified, followed by comprehensive evaluation using the CRITIC method and correlation analysis.Resu...
