Reaserch on extraction technology of polysaccharides from Acanthopanax senticosus waste residue by response surface methodology / 中草药

ABSTRACT

Objective To study and optimize the extraction technology of polysaccharides from Acanthopanax senticosus (AS) waste residue by response surface methodology (RSM). Methods Phenol-sulfuric acid method was used to quantitatively analyze polysaccharides from AS waste residue. Based on single factor, the extraction process factors of polysaccharides from AS waste residue were optimized by RSM. Results The best conditions for the response surface optimization were as follows extraction temperature was 80 ℃, extracting time was 1.5 h, and liquid-material ratio was 21. The extraction rate of polysaccharide was 10.14% under the optimal conditions. Conclusion The extraction conditions of the polysaccharide from AS are optimized by response surface method. This data can provide a theoretical basis for the further exploitation and utilization of the subsequent waste residue of AS.
