摘要
利用水提醇沉法从沙棘叶和沙棘果皮中提取多糖,再经初步纯化后,采用琼脂平板扩散法进行抑菌试验。结果表明,沙棘多糖对大肠杆菌、四叠菌等有一定的抑制作用。
By means of water extraction and ethanol precipitation, polysaccharide is obtained from seabuckthorn pericarp and leaves After initial purification, bacteriostasis experiment is conducted in agar plate dilution method The results show that seabuckthorn polysaccharide has inhibitional effects to bacteria such as coliform
