Objective: To study the aqueous chemical constituents of the flower buds of Eugenia caryophylla.
Methods: The compounds were isolated by HP-20 resin column chromatography, RP-C18 column chromatography, preparative RP-C18 thin-layer chromatography, preparative RP-C18 high performance liquid chromatography, and their structures were established by NMR and MS evidences.
Results: Five compounds were separated from the water extracts.
[Study on transdifferentiation of renal tubular cells in rat chronic renal interstitial fibrosis induced by Radix Aristolochiae Fangchi Extract].

Center for Health Food Evaluation, State Food and Drug Administration, Beijing 100061, China.
Objective: To investigate the relationship between renal tubular cells transdifferentiation and chronic renal interstitial fibrosis induced by Fangchi Extract in rat.
Method: The chronic renal interstitial fibrosis rat model was made by giving Radix Aristolochiae Fangchi extract (RAFE) and aristolichic acid (AA) respectively to rats through infusing stomach about 22 weeks discontinuously. Through immunnal histochemistry methods, investigating the expression of symbol proteins: Cytokine( CK) , alpha-Smooth muscle actin ( alpha-SMA) and Vimentin, and also the important fibrosis inducing factor-Transforming growth factor-beta (TGF-beta1 )on renal tubular cells.
