Pumpkin polysaccharide in vitro simulator under artificial gastric juice
The aim of this paper was to research pumpkin polysaccharide in vitro simulator under the artificial gastric juice.An water-soluble polysaccharide(PP) was extracted by water extraction,and organic solvent extraction step by step,and so on.The molecular weight and the changed of reducing sugars of the pumpkin polysaccharide after 30 min,90 min,150 min,720 min were detected under in vitro artificial gastric juice.The result showed that the amount of reducing constantly slow increase as time,and small molecular sugar appears in the 30 min,while the high molecular changes in the 90 min through HPLC.Reducing sugars and oligosaccharide could produce in vitro artificial gastric juice.
