Abstract
Two new phenylpropanoid glycosides, named cistanoside A (III) and cistanoside B (IV), were isolated from the whole plant of Cistanche salsa (C. A. MEY.) G. BECK (Orobanchaceae), together with acteoside (I) and echinacoside (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-glucopyranosyl-(1→6)]-(4-O-caffeoyl)-β-D-glucopyranoside and 2-(4-hydroxy-3-methoxyphenyl) ethyl O-α-L-rhamnopyranosyl-(1→3)-O-[β-D-glucopyranosyl-(1→6)]-(4-O-feruloyl)-β-D-glucopyranoside, respectively, on the basis of chemical and spectral data.
