Abstract:

The extraction rate of organic acid components was used as an indicator to investigate the effects of extraction process parameters, namely, extraction temperature, extraction time, solid-liquid ratio, and particle size on the extraction results using the water extraction method. A response surface model was established using a Box-Behnken design to optimize the extraction process parameters for organic acid components from Lonicera japonica Thunb. with temperature, time, and solid-liquid ratio as factors. Results show that the optimal extraction process for organic acid components from Lonicera japonica Thunb. comprise an extraction temperature of 72 ℃, an extraction time of 90 min, and a solid-liquid ratio of 1 g∶40 mL. Under these conditions, the extraction rate of organic acid components can reach 5.16% with a relative error of 0.96% compared to the theoretical value.

Key words: Lonicera japonica Thunb., organic acids, extraction, the response surface methodology
