Compared to the control group, the callus area in the GSE group was increased by 1.8-fold on day 3 and by 2.0-fold on day 10. The most favorable healing effect was observed in the GSE50 group, this fraction was primarily composed of gentisin (27.6%), gentiopicroside (7.3%) and isoorientin (65.1%). A notable dose-response relationship was observed between gentisin and isoorientin concentrations in GSE and bone repair outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Our findings demonstrate that the active metabolites in GSE are potent agents for accelerating fracture repair.
