摘要
沙棘果皮沸水煮提得到粗多糖，经纸层析及气相色谱分析，该粗多糖组成为Ａｒａ，Ｆｕｃ，Ｘｌｙ，Ｇａｌ，Ｍａｎ，Ｇｌｃ和ＧａｌＡ．粗多糖经酸性乙醇分级得四个级分．将对柯萨奇病毒（ＣｏｘｓａｃｋｉｅＢＶｉｒｕｓ，ＣＢＶ）Ｂ３有初步抑制作用的ＨＲ３用ＤＥＡＥ－ＳｅｐｈａｄｅｘＡ－２５柱层析进一步分级，得到２个级分Ｈｎ和Ｈａ．Ｈｎ是由Ａｒａ，Ｇａｌ，Ｍａｎ和Ｇｌｃ组成的中性杂多糖，对柯萨奇病毒Ｂ３具有明显的抑制作用．
The crude polysaccharide was isolated by boiling water. PC and GC show it consists of Ara, Fuc, Xly, Gal, Man, Glc and GalA. The crude polysaccharide has been fractionated with acidified ethanol. Four fractions were got respectively. HR 3 has anti-virus activity. HR 3 was further purified by chromatography on a columm(2 5×90 cm) of DEAE-Sephadex A-25. Two fractions were obtained. They are neutral component H n and acidic component H a. H n has notable anti virus (CBV 3) activity.
