beta d fructopyranoside/neoplasms

OBJECTIVE To study the anti-tumor metastatic constituents from Ardisia Crenata. METHODS Chemical constituents were isolated and purified by repeated column chromatography( silica gel, Toyopearl HW40C and preparative HPLC). Their structures were elucidated on the basis of spectral data analysis. The

The purification of the MeOH extract from the rhizome of Sparganium stoloniferum Buch.-Hamil. (Sparganiaceae) using column chromatography furnished one new phenylpropanoid glycoside (7) and known phenolic compounds (1-6, and 8-13). The structural elucidation of 7 was based on 1D- and 2D-NMR

To investigate the chemical constituents of Clematis aethusifolia,a traditional Mongolian medicine for resolving hard lump. Bioactive guided isolation and purification of Clematis aethusifolia was performed by normal and reverse phase column chromatography, Sephadex LH-20 and preparation HPLC. The
