Chemical constituents of the whole plants of Saussurea medusa

摘要

The chemical constituents of the traditional Tibetan medicine of Saussurea medusa Maxim. (Compositae) were investigated and a new flavonoid glucoside, together with 14 known compounds, was isolated. The structure of the new compound was established as 6″-O-crotonoylhomoplantaginin by using one- and two-dimensional nuclear magnetic resonance spectroscopy and mass spectrometry analyses.
