RESUMO

OBJECTIVE: To study the chemical constituents of Phyllodium elegans. METHODS: The compounds were isolated and purified by extraction, chromatography on silica gel and recrystallization. Their structures were elucidated on the basis of physicochemical properties and spectra analysis. RESULTS: Three triterpenoids were isolated and identified as lupenone (1), lupeol (2), betulin (3). CONCLUSION: Compound 2 is obtained from the genus for the first time, Compounds 1-3 are isolated from this plant for the first time.

RESUMO

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.
