Three new phenylpropanoid glycosides, named luteoside A (3), luteoside B (4), and luteoside C (5), were isolated together with the known compounds verbascoside (1) and isoverbascoside (2) from the roots of the medicinal: plant Markhamia lutea. The structures of the new compounds were determined to be 1-O-(3,4-dihydroxyphenyl)ethyl β-D-apiofuranosyl(1→2)-αL- rhamnopyranosyl(1→3)-4-O-caffeoyl-6-acetyl-β-D-glucopyranoside, 1-O-(3,4- dihydroxyphenyl)ethyl β-D-apiofuranosyl(1→2)-α-L-rhamnopyranosyl(1→3)-6- O-cafeoyl-β-D-glucopyranoside, and 1-O-(3,4-dihydroxyphenyl)ethyl β-D- apiofuranosyl(1→2)-α-L-rhamnopyranosyl(1→3)-6-O-feruloyl-β-D- glucopyranoside, respectively, on the basis of chemical and spectroscopic data. All five phenylpropanoid glycosides exhibited potent in vitro activity against respiratory syncytial virus.

Four new phenylethanoid glycosides, tubulosides A (II), B (VI), C (VII) and D (VIII), have been isolated from Cistanche tubulosa (SCHRENK) HOOK. f. (Orobanchaceae), together with four known phenylethanoid glycosides, echinacoside (I), acteoside (III), acteoside isomer (IV) and 2'-acetylacteoside (V).The structures of II, VI, VII, and VIII were established on the basis of chemical evidence and spectral data.Compounds VII and VIII possess a triacetylrhamnosyl moiety as the terminal sugar.Keywords--Cistanche tubulosa; Orobanchaceae; parasitic plant; phenylethanoid glycoside; tubuloside A; tubuloside B; tubuloside C; tubuloside D
