Methods: (1)To separate stilbene glycoside by using silica gel column chromatography with gradient elution consisting of ethyl acetate and petroleum ether.
方法：（1）以硅胶柱色谱法，乙酸乙酯-石油醚梯度洗脱，自何首乌中提取分离二苯乙烯苷单体成分。
2
On SDS-polyacrylamide gel electrophoresis (SDS-PAGE)the eluate from the column with the McAb coupled showed a single band, corresponding to the elution peak.
