Study on Extraction Technology of Polysaccharide from Leaves of Vaccinium uliginosum L.

Abstract

Abstract: In order to develop the resources of Changbai Mountain thoroughly, extraction the polysaccharides in the Vaccinium uliginosum L. was studied in the present paper. Through a comparison analysis and L9(34) orthogonal design, the extracting time, temperature, ratio of solid to liquid and the times were investigated respectively. The results indicated that the temperature was very significant and then the ratio of solid to liquid, the extracting time. The optimal conditions in the extracting procession were as follow: temperature 90 ℃, extracting time 4 h, ratio of solid to liquid 1:30 and extracting times 2. On the optimal conditions the extracting rate of polysaccharides could approach to 12.46%.

Key words: Vaccinium uliginosum L., leaves, polysaccharides, extraction technology
