Objective: To optimize the process of polysaccharides extraction from Ornithogalum caudatum ait. Method: Wa-ter extraction and alcohol precipitation method was used to extract crude polysaccharide from Ornithogalum caudatum ait. Single factor experiment was used to screen the main influencing factors and the polysaccharide content was taken as the index. The impacts of solid-liquid ratio, extraction times, extraction temperature and extraction time on the content of crude polysaccharide from Ornitho?galum caudatum Ait were analyzed. Results: Single factor experiment results showed that the best material liquid ratio was 1:25, the extraction times was 3, the extraction temperature was 90℃ and the extraction time was 3h. The polysaccharide content was detect-ed to be 9.79%. Conclusion: The extraction process is simple and the condition is easy to control, which provide basis for the develop-ment and utilization of Ornithogalum caudatum Ait.
