Objective: To study Banlangen levels of adenosine in different dosage forms

and compare betweendifferent anti-inflammatory agents. Method: HPLC determination of Radix syrup

Banlangen

Radix soft capsules

tablets Radix

Radix Pill formulations of adenosine content column for the Dia-monsil Cl8 (4.6 mm×200 mm

5 μm)

detection wavelength of 260 nm

flow phase: methanol - water (10 : 90)

flow rate: 1.0 mL·min-1

column temperature 30 ℃. After the administration of the other mice

xylene-induced ear swelling coated

comparing the group differences in degree of swelling. Result: Adenosine in the range of 0.016 0-0.160 0 g good linear relationship ( r = 0.999 7)

the average recovery was 98.7%

RSD 0.79% ( n = 9). Radix soft capsules in which the highest concentrationsof adenosine

followed by the Banlangen

board Radix tablets

pills Radix

Radix syrup. In xylene-induced mouse ear edema model of anti-inflammatory

anti-inflammatory effect Banlangen best

followed by the Radix softcapsules

pills Radix

Radix film

Radix syrup. Conclusion: The method precision

good reproducibility

accurate

and efficacy of adenosine has some relevance but not absolute

the other anti-inflammatory agents may produce asynergistic ingredients.
