Regarding the harvest time for 4-year-old plants, September 26 yielded the highest score at 0.87, followed by October 16 at 0.46, whereas September 11 received the lowest score at 0.41. Among the drying methods, shade drying resulted in the highest quality, ranking as follows: shade drying &amp;gt; step-down drying (105\u201380\u202f\u00b0C)\u202f&amp;gt;\u202fhigh-temperature drying (&amp;gt;80\u202f\u00b0C)\u202f&amp;gt;\u202fsun drying &amp;gt; low-temperature drying (60\u202f\u00b0C). Correlation analysis revealed a significant positive correlation between paeoniflorin content and root dry weight across different harvesting ages. Additionally, paeoniflorin showed significant positive correlations with the contents of catechin, oxidized paeoniflorin, and lactiflorin across different harvesting dates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The present findings are specific to Tongliao City, Inner Mongolia, and are not universally applicable.
