[Studies on the chemical constituents from Cissus pteroclada].

OBJECTIVE: To study the chemical constituents of Yao Medicine Cissus pteroclada. METHODS: The compounds were isolated and purified by column chromatography with silica gel, TLC and recrystallization. Their structures were elucidated on the basis of physicochemical properties and spectra analysis. RESULTS: Six compounds were isolated and identified as beta-sitosterol (I), bergenin (II), 11-O-galloylbergenin (III), 11-O-(4-hydroxy benzoyl) bergenin (IV), gallic acid (V), daucosterol (VI). CONCLUSION: Compounds III and NIV are obtained from the genus for the first time. All the compounds are isolated from this plant for the first time except the compound II.
