Abstract: Organic solvent extraction and D101 macroporous absorption resin chromatography were used to purify phenylethanoid glycosides (PEG) from Cistanche salsa, and the antioxidant activity of phenylethanoid glycosides was assessed by reducing power, DPPH radical-scavenging capacity and ferric thiocyanate (FTC) method. The results indicated that D101 macroporous absorption resin chromatography is more suitable for the purification of phenylethanoid glycosides, and the obtained phenylethanoid glycosides exhibit stronger antioxidant capacity compared with the positive control vitamin E.

Key words: Cistanche salsa, phenylethanoid glycosides, purification, antioxidant activity1
