Abstract:

Based on single factor tests,the optimum extraction conditions of polysaccharides from argy wormwood leaves were obtained through Box-Benhnken central combination design and RSM. The results showed that the optimum extraction conditions of polysaccharides are as follows: ratio of material solvent 1:18, extraction temperature 97 ℃, extraction time 1.2 h and extraction times 3. Under such conditions, the one-time extraction rate is up to 1.529%.

Key words: argy wormwood leaves, polysaccharides, extraction, response surface methodology
