[Chemical constituents of Cynanchum chinense R. Br]
Objective:
To investigate the chemical constituents in the aerial part of Cynanchum chinense.
Method:
The chemical constituents were extracted with solvent and separated by column chromatography. The structures were identified by spectral methods:
Result:
The structures were identified as 7-O-alpha-L-rhamnopy-ranosyl-kaempferol-3-O-alpha-L-rhamnopyranoside, 7-O-alpha-L-rhamnopy-ranosyl-kaempferol-3-O-beta-D-glucopyranoside and 7-O-alpha-L-rhamnopyr-anosylkaempferol-3-O-beta-D-glucopyranosyl(1-->2)- beta-D-glucopyranoside.
Conclusion:
All the three compounds were separated from C. chinense for the first time.
