Abstract: Six compounds were separated from Fuzhuan Tea by using the combined modern separation technique with High-Throughput Screening(HTS) technique. After using IR,UV, MS, NMR , etc., the compounds were identified as follows: gallic acid(GA), (+)-gallocatechin 〔(+)-GC〕, 3-methoxy-4,5-dihydroxy-benzoic acid(MDBA), 3,4-dihydroxy-benzoic acid(DBA), (-)-epigallocatechin gallate〔(-)-EGCG) and (-)-epicatechin gallate((-)-ECG〕. The six compounds separated from Fuzhuan Tea were tested by cell model FXR, LXR, PPARδ, PPARγ and 3T3-L1. These results showed that the concentration of 50.00µg/mL GA and ECG were active in the FXR model. The active value was 1.77±0.14 and 3.22±0.06 separately. The active value of EGCG in the FXR model reached 6.00±0.45 when the concentration was 50.00µg/mL. To PPARδ, the active value of GC in PPARγ model was 1.62±0.16 when the concentration was 30.00µg/mL. The active value in MDBA to PPARγ was 1.73±0.16. All the compounds were not obviously active in 3T3-L1 model.
