Method for enriching and separating phenylethanoid glycoside compounds from herba cistanche extract

The invention relates to a method for enriching and separating phenylethanoid glycoside compounds from herba cistanche extract. The method comprises the following steps of enriching phenylethanoid glycoside compounds in herba cistanche extract by using hydrophobic macroporous adsorption resin, eluting by using a gradient polar eluent, and separating the phenylethanoid glycoside compounds such as echinacoside, acteoside and isoacteoside to obtain high-purity echinacoside, acteoside and isoacteoside preparations, or combining eluents. and the herba cistanche extract preparation with stable and controllable quality is obtained. 本发明涉及一种由肉苁蓉萃取物中富集及分离苯乙醇苷类化合物的方法。利用疏水性大孔吸附树脂富集肉苁蓉萃取物内的苯乙醇苷类化合物，再以梯度极性洗脱剂洗脱，将松果菊苷、类叶升麻苷及异类叶升麻苷等苯乙醇苷类化合物分离，得到高纯度的松果菊苷、类叶升麻苷及异类叶升麻苷制剂，或合并洗脱液，得到质量稳定可控的肉苁蓉萃取物制剂。
