Abstract: This paper studied the extraction technique of water-soluble polysaccharides and total flavone from Ampelopsis grossedentata.The optimal technical conditions of extraction of the polysaccharides were obtained by central composite design and response surface analysis as follows: extraction temperature 95℃, ratio of solid-liquid 1:25 and extraction time 4h. The polysaccharides were precipitated with 3 times volume of 95% ethanol for 2h. The synthetical extracting technique of water-soluble polysaccharides and total flavone from Ampelopsis grossedentata has been fixed tentatively.

Key words: Ampelopsis grossedentata, polysaccharides, total flavone, extraction, RSA
