Arylethyl (= Phenylethanoid) Glycosides and Oligosaccharide from the Stem of Cistanche tubulosa

Three new analogues of the arylethyl (= phenylethanoid) glycoside echinacoside (5), namely cistantubulosides A (1), B1/B2 (2a/2b), and C1/C2 (3a/3b), and one new oligosaccharide, cistantubulose A1/A2 (4a/4b), were isolated from the stems of Cistanche tubulosa (Schenk) R. Wight, together with five kn...

Summary:Three new analogues of the arylethyl (= phenylethanoid) glycoside echinacoside (5), namely cistantubulosides A (1), B1/B2 (2a/2b), and C1/C2 (3a/3b), and one new oligosaccharide, cistantubulose A1/A2 (4a/4b), were isolated from the stems of Cistanche tubulosa (Schenk) R. Wight, together with five known compounds, i.e., campneoside I, campneoside II (6), echinacoside (5), tubuloside, and cistanoside F. Among the compounds isolated, 2a/2b, 3a/3b, 4a/4b, campneoside I, campneoside II (6), and cistanoside F each consisted of a pair of epimers. The structures of the new compounds were elucidated on the basis of spectral data.
