Two new phenylpropanoid glycosides, named cistanosides E (III) and F (IV), were isolated from Cistanchis Herba, the whole plant of Cistanche salsa (C. A. MEY.) G. BECK (Orobanchaceae), together with two known lignan glycosides, liriodendrin (I) and (+)-syringaresinol O-β-D-glucopyranoside (II). The structures of III and IV were determined to be 2-(4-hydroxy-3-methoxyphenyl) ethyl O-α-L-rhamnopyranosyl-(1→3)-O-β-D-glucopyranoside and α-L-rhamnopyranosyl (1→3)-O-(4-O-caffeoyl)-D-glucopyranose, respectively, on the basis of chemical and spectral data.
