Abstract：Gardenia jasminoides flowers haveedible，medicinal，andcosmeticvalue.To investigatetheefctof flowering timeonthefunctionalcomponentsandantioxidantactivitiesofGardeniajasminoides，andtoidentifythebestharvesting periodfordiffrentapplications，we measuredthecontentoffunctionalcomponentsandtheantioxidantactivitiesof Gardeniajasminoidesatdiffrentflowering stages，andexploredthecorelationsbetween thesecomponentsandtheirantioxidantactivities.Thefindings indicatedthatthereweresignificantdiferencesinthecontentoffunctionalcomponentsof Gardeniajasminoidesflowersat different flowering stages. The contentsofprotein，carbohydrate，and dietaryfiberwere thehighest in the blooming stage. The highest concentrations of geniposide，total phenols，total flavonoids，and total iridoids were recorded during the emergence stage，at （ 27.55±2.76 ）mg/g，（35.30±0.67）mg/ g ，（17.09±0.93） mg/g ，and（101.70±3.02）mg/g，respectively. Significant

positivecorrelations were identified between the contents of total flavonoids and total iridoids with 2，2′ -azino-bis （3-ethylbenzothiazoline-6-sulfonicacid）（ABTS）radical scavengingcapacity，1，1-diphenyl-2-picrylhydrazyl（DPPH）radical scavenging capacity and ferric reducing antioxidant power （FRAP）（ r>0 ！ P<0. 05）in Gardenia jasminoides flowers.A significant positive correlation was also found between total phenolcontent and the DPPH radical scavenging capacity（ r>0 ， （2號 P<0.05 ）.Comprehensive analysis revealed thatGardenia jasminoides flowers in the blooming stage had the highest nutritional value，whilethoseintheemergencestage exhibitedthe strongest antioxidantactivity.Consideringboth yieldand quality，Gardenia jasminoides flowers in the emergence and blooming stages have higher medicinal value.
