| Abstract: | Objective: To study the optimum extraction for the polysaccharide of Saussurea with water. Methods: Some influential factors during extraction process with water Are investigated through two quality indexes (including contents of rate of dry extract and Polysaccharide in extract) by L9 (3) 4 orthogonal test. Results: results of the experiment and variance analysis indicate that the extracting number of times are main factors. The water amount and boiling time affect insignificantly total polysaccharide of Saussurea. Conclusion: The optimum extraction is as follows: adding 10 times amount of water into medicinal materials originally, and boiling for 60 min each time, exacting three times in all. |
