| Abstract: | Polysaccharide has many physiological functions such as controlling blood sugar, reducing blood fat and cholesterol. The test extract polysaccharides of Psidium guajava leaves by ethanol degreasing method.The extraction rate of polysaccharide is 15.3%, 9.7%. The contents of polysaccharide in sweet potato leaves and Psidium guajava leaves was determined (were assayed) by Phenol-Vitriolic (with phenol-H2SO4 colorimetry). The content of polysaccharide is 5.70%. So it has market prospect to develop sweet potato leaves as a kind of functionality and nourishing food. |
