Abstract:
Objective: To explore the difference of anti-inflammatory effects in vitro and in vivo between Canqiang, Tiaoqiang and Datouqiang, and to obtain the anti-inflammatory active substances by relation of fingerprint with pharmacodynamics. Methods: Dimethylbenzene for the induction of a mouse ear edema in vivo and LPS-stimulated RAW 264.7 cells in vitro were used to investigate the anti-inflammatory activity, inflammatory factors such as nitric oxide (NO), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were determined by NO kit and ELISA kit, and the gray correlation analysis method was used to analyze the correlation between the peak area and the anti-inflammatory activity of the fingerprint features of each sample. Results: Different commercial specifications presented inhibition on acute inflammation of ear edema and inflammatory factors NO, TNF-α and IL-6, and anti-inflammatory effects were Canqiang > Datouqiang > Tiaoqiang. The chemical composition represented by 40 characteristic peaks was related to anti-inflammatory activity, and 17 characteristic peaks were highly correlated with this effect, among which three peaks were known components, namely chlorogenic acid, ferulic acid and isoimperatorin. Conclusion: The anti-inflammatory effect of Canqiang was the most significant, which was consistent with Canqiang being the most expensive and effective in the market, also with traditional grading standards. This study initially obtained anti-inflammatory active substances were chlorogenic acid, ferulic acid and isoimperatorin.
