朝鲜白人参经50%MeOH 于室温提取3次,每次4天,合并提取液,减压浓缩,得提取物,与纤维素混合上纤维素柱,用MeOH,50%MeOH 及水洗脱。水洗脱部分于纤维素柱内对水透析4天,不被透析的蛋白质经DEAE 纤维素柱层析,用0.05 MTris-HCl 缓冲液(pH8.0,NaCl 浓度0～0.5M)洗,得两个组分P-1和 Korean white ginseng was extracted three times for 4 days at room temperature with 50% MeOH. The extracts were combined and concentrated under reduced pressure to give an extract. The cellulose column was mixed with cellulose and eluted with MeOH, 50% MeOH and water. The eluted fraction was dialysed against cellulose for 4 days in a cellulose column. Proteins that were not dialyzed were subjected to DEAE cellulose column chromatography and washed with 0.05 MT Tris-HCl buffer (pH 8.0, NaCl concentration 0-0.5 M) Two components P-1 and
