Abstract:

To seek out the optimal water-extracting technology of polysaccharides from (Canarium album Lour.) Raeusch. The paper was to study an optimal procedure of polysaccharides from (Canarium album Lour.) Raeusch consisting of hot water extraction. A series of single factor experiment were conducted to investigate effects of solid/liquid ratio, extraction temperature, extraction time, extraction times on (Canarium album Lour.) Raeusch polysaccharides yield. On the basis of this, three main affect factors, including solid/liquid ratio, extraction temperature, extraction time were optimized for maximizing (Canarium album Lour.) Raeusch polysaccharides yield. Using a orthogonal array design. The results showed that the optimal preparation procedure of (Canarium album Lour.) Raeusch polysaccharides consisted of solid/liquid ratio of 1:8, the extraction temperature at 100℃ with 3.5 h, the yield of (Canarium album Lour.) Raeusch polysaccharides was 7.10%. These extraction process is feasible，and the experiment result can provide basic and instruction data for the ascertainment of water extraction technology of (Canarium album Lour.) Raeusch polysaccharides.
