Abstract:
Objective To optimize the processing integration technology of Fraxini Cortex based on response surface methodology. Methods The single factor experiment combined with Box-Behnken design was used to optimize the integrative technology, with five major characteristic components (aesculin, aesculetin, fraxetin, fraxin, and total coumarin) as indexes, in order to detect three factors (cutting thickness, drying temperature, and drying time), and research the effect of analgesic and anti-inflammatory of processing integration Fraxini Cortex. Results Optimum integrative technology of primary processing was as follows: cutting 6 mm Fraxini Cortex, and drying for 3.25 h at 75 ℃. The processing integration Fraxini Cortex significantly decreased the times of wrinkle reaction induced by acetic acid in mice, prolonged the latent period, and obviously or partially inhibited the feet swelling degree induced by carrageenan in rats. The analgesic effect of integrated technology group was more obvious than traditional technology group (P < 0.05). Conclusion This optimized integrative technology of Fraxini Cortex is reasonable and feasible with high accuracy. It could provide the scientific basis and innovative idea to the large-scale production of decoction pieces of Chinese materia medica and have the certain value for its promotion and application.
