Phenylethanoid glycosides structure elucidation

ISOLATION, STRUCTURE ELUCIDATION AND BIOACTIVITIES OF PHENYLETHANOID GLYCOSIDES FROM CISTANCHE, FORSYTHIA AND PLANTA GO PLANTS... 

We shall describe the isolation and structure elucidation and HPLC analysis of the phenylethanoid glycosides from several Cistanche plants growing in China, Mongoria, Kazakhstan, Pakistan, Turkey, Bahrain and Qatar, and from Forsythia plants and Plantago plants used as important herbal medicines. 

Five new phenylethanoid glycosides, tubuloside A-E (18-22) were isolated and their structures were elucidated, together with six known glycosides, acteoside (1), 2-acetylacteoside (2), isoacteoside (3), echinacoside (4), syringalide A 3 -a-L-rhamn oside (15), isosyringalide A 3 -a-L-rhamnoside (16), from C. tubulosa in Pakistan [18,19],... 

Structure elucidation of phenylethanoid glycosides from Ciatanche plants... 

Structure elucidation of phenylethanoid glycosides were carried out on the basis of spectral analysis and chemical evidences. Assignment of the 13C-NMR chemical shifts of phenylethanoid glycosides were re-examined and shown in Table 2. [24] Two dimensional NMR spectra, such as HfCOSY), H-... 

Studies on the structure elucidation of phenylethanoid glycosides of °C-NMR, the change of chemical shift value were observed.
