|Cimifugin inhibits allergic contact dermatitis by regulating type 2 cytokines.[Reference: WebLink]|
|This study was carried out to investigate the effective and mechanism of Cimifugin on type 2 allergic contact dermatitis induced by FITC. |
METHODS AND RESULTS:
The BALB /c mice were sensitized with FITC on days 1 and 2,on the shaved abdomen skin. On day 6,the animals were challenged on their right ears with FITC. Simultaneously,the mice were administered Cimifugin from day 1 to day 5. On day 7,ear swelling was measured and the infiltration of lymphocytic was investigated by hematoxylin and eosin( HE) staining. The levels of IL-4,IL-9,IL-13 and IFN-γ were quantified by ELISA and BCA. The results suggested that mouse ear swelling was dramatically inhibited by25 mg /kg,50 mg /kg Cimifugin. Histopathological results indicated that mice given Cimifugin has significant improvement on local tissue fluid exudation,congestion,and lymphocytic infiltration was remarkably reduced by Cimifugin. At the same time type 2 cytokines IL-4,IL-9,IL-13in the mouse ear tissue homogenate were obviously reduced by Cimifugin,while no significant changes with type 1 cytokines IFN-γ.
Cimifugin evidently inhibited FITC-induced type 2 allergic contact dermatitis,and its mechanism might related to regulating the balance of Th1 /Th2 by inhibiting type 2 cytokines.

|Development of an Efficient Protocol for Cimifugin Isolation from Peucedanum schottii and Evaluation of Enzyme Inhibitory Activity.[Reference: WebLink]|
METHODS AND RESULTS:
The dichloromethane extract of the fruits of Peucedanum schotti Besser ex DC. (Apiaceae) was subjected to high-performance counter-current chromatography (HPCCC) for the efficient and fast separation (30 min) and subsequent isolation of Cimifugin using ethyl acetate: water (1:1 v/v, K = 1.01) system.
Separation was further optimized on analytical scale and then easy up-scaled to semipreparative conditions. A total of 135 mg of Cimifugin (96.5% purity) was purified from 1.2 g of the dichloromethane extract (11.25% yield). Cimifugin was isolated for the first time from P. schotti and characterized by NMR spectroscopy. Further Cimifugin, along with the crude extract were evaluated for their inhibitory potential against cholinesterases (acetylcholinesterase - AChE and butyrylcholinesterase - BChE) and tyrosinase (TYR), key enzymes for the treatment of some neurodegenerative diseases, i.e. Alzheimer’s and Parkinson’s, using ELISA microtiter assays.
The crude extract exhibited a weak inhibitory activity against AChE, BChE, and TYR (4.19, 35.47, and 0% at 100 μg mL-1 and 10.26, 40.03, and 12.25% at 200 μg mL-1, respectively), while Cimifugin displayed low to moderate inhibition towards AChE and BChE (3.12 and 21.63%, respectively) at 200 μg mL-1.

| Comparative pharmacokinetics of prim-O-glucosylcimifugin and cimifugin by liquid chromatography-mass spectrometry after oral administration of Radix Saposhnikoviae extract, cimifugin monomer solution and prim-O-glucosylcimifugin monomer solution to rats.[Pubmed: 22253022]|
|A sensitive and reliable liquid chromatography-mass spectrometry method has been developed and validated for simultaneous determination of Cimifugin and prim-O-glucosylCimifugin in rat plasma after oral administration of Radix Saposhnikoviae (RS) extract, prim-O-glucosylCimifugin monomer solution and Cimifugin monomer solution.
METHODS AND RESULTS:
Plasma samples were pretreated by protein precipitation with acetonitrile containing the internal standards puerarin and daidzein. LC separation was achieved on a Zorbax SB-C(18) column (150 × 4.6 mm i.d., 5 μm) with 0.1% formic acid in water and methanol by isocratic elution. The detection was carried out in select-ion-monitoring mode with a positive electrospray ionization interface. The fully validated method was successfully applied to the pharmacokinetic study of the analytes in rats. A bimodal phenomenon appeared in the concentration-time curve of prim-O-glucosylCimifugin and Cimifugin after oral administration of RS extract. Prim-O-glucosylCimifugin mainly transformed to Cimifugin when it was absorbed into blood. Both absorption and elimination of Cimifugin after oral administration of RS were longer than after administration of single Cimifugin.
The pharmacokinetic parameters (AUC(0-t) , AUC(0-∞) and t(1/2) ) of prim-O-glucosylCimifugin and Cimifugin by giving Cimifugin monomer solution, prim-O-glucosylCimifugin monomer solution and RS extract had significant differences (P < 0.05).
