The extraction technology of Exocarpium Benincasae Polysaccharide (EBP) was studied. The orthogonal experimental design method was applied to determine the influence of extraction factors on the mount of EBP such as water used, extraction time and times. The content of EBP was analyzed with phenol-sulphruic acid method. The result showed that the best technology for extraction of EBP was 10 times water;repeating three times and 2 hours for each turn. The process is stable and of high efficiency in polysaccharide extraction. It will benefit the development of new hypoglycemic drugs and the medicinal resources accumulation of wax gourd conditions.
