Phenolic glycosides from Rhodohypoxis baurii.

Three new phenolic glycosides (1-3), together with a known glycoside (4), were isolated from the bulbs of Rhodohypoxis baurii (Hypoxidaceae). The structures of the new glycosides (1-3) were determined on the basis of extensive spectroscopic analyses, including two-dimensional (2D) NMR data, and of hydrolytic cleavage followed by chromatographic or spectroscopic analyses.
