OBJECTIVE： To optimize and improve the quality standard for Citrus reticulata formula granules. METHODS： Totally 13 batches of C. Reticulata formula granules from 4 different manufacturers were used as trial samples， and qualitative identification of hesperidin and nobiletin in the samples were carried out by TLC according to the method of 2015 edition of Chinese Pharmacopoeia （part Ⅳ）. The quantitative analysis of naringin， hesperidin， hesperetin， nobiletin and tangeretin in C. reticulatae formula granules were conducted by UPLC[The determination was performed on Waters Acquity UPLC BEH C18 column with mobile phase consisted of acetonitrile-0.2％ phosphoric acid aqueous solution （gradient elution）. The detection wavelength was set at 283 nm， and sample size was 3 μL]. RESULTS： The results of TLC showed that in the chromatograms of samples， same color spots were shown in the corresponding positions of the chromatogram of reference substance. The results of UPLC showed， that the linear range of naringin， hesperidin， hesperetin， nobiletin and tangeretin were 0.64-6.44， 15.78-157.80， 0.17-1.66， 2.08-20.85 and 2.04-20.43 μg/mL， respectively （all r≥0.999 2）； the limits of detection were 0.03， 0.33， 0.10， 0.20 and 0.06       μg/mL； the limits of quantitation were 0.07， 1.34， 0.20， 0.60 and 0.22 μg/mL. The average recoveries were 99.4％， 99.6％， 99.7％， 99.7％ and 99.7％ （n＝9）； RSDs of precision （n＝6）， stability （n＝7） and reproducibility （n＝6） tests were all≤2.03％； naringin was detected in only 3 batches of samples from one manufacturer （the content ranged from 0.067 3 to 0.069.6    mg/g）， while the other 4 components were detected in 13 batches of samples （the contents of them ranged 0.646 5-1.728 0，   0.102 6-0.290 5， 0.023 1-0.689 8， 0.018 2-0.270 7 mg/g）. CONCLUSIONS： In this study， the quality standard of C. reticulata formula granules was improved by qualitative and quantitative methods， and the contents of hesperidin， hesperetin， nobiletin and tangeretin were not less than 0.60， 0.10， 0.02 and 0.01 mg/g， respectively.
