The Extraction of Polysaccharide for Watkins Jujube

Abstract:

The main material is watkins jujube, and the best conditions of the extract of polysaccharide is considered. The polysaccharide can be obtained from jujube juice by decolourizating, concentrating，alcohol- precipitating and drying. The best conditions of decolourizating are as follows: activity carbon content is 1.0%, temperature is 90°C, the decoloration of two times is 1.5 hours. The best conditions of alcohol-precipitating are using 95% ethanol whose volume fraction is 60%, precipitating by 1 hour, and being dried by freeze drying. The extraction yielding of polysaccharide is 1.2%.
