Abstract: Based on one-factor-at-a-time experiments, response surface methodology was used to optimize the extraction of red pigments from the fresh fruits of Acanthopanax senticosus Harms wildly grown in Changbai Mountain. The optimal extraction conditions were found as follows: 36.83% ethanol as extraction solvent, 23.78:1 material-to-liquid ratio, and 2.05 h extraction time. Under these conditions, the predicted and experimental absorbance values at 525 nm of extracts was 0.756 and 0.751, respectively.

Key words: Acanthopanax senticosus Harms, pigment, response surface methodology, extraction
