Abstract: Objective:To optimize the best extraction process of polysaccharides in bamboo leaves.Methods:With polysaccharides of bamboo leaves being an examinable target component,the optimized extraction techniques and condition were chosen by orthogonal test method.Results:The best extraction process of polysaccharides of bamboo leaves was that the crude drugs were extracted with petroleum ether for refluxed 2 h,the sediments extracted with 95% ethanol for 2 h first,then filtrable residue from previous steps were extracted three times with 30 times amount of water.The proteins were removed by Sevage’s method,adding ethanol and making its concentration to 80%,the extracts were stored in the refrigerator for 12 h.The acquired amount of bamboo leaves polysaccharides was about 0.51% from the best extraction process.Conclusion:The extractive rate of bamboo leaves polysaccharides was higher in the optimized extraction process and the process was proved to be reasonable and feasible.
