OBJECTIVE: To investigate the chemical constituents in the roots and rhizomes of Sinopodophyllum emodi. METHODS: The compounds were isolated by many different chromatographic methods such as silica gel, Sephadex LH-20, and ODS column. Their structures were identified by their physicochemical properties and spectrascopic data. RESULTS: Nine compounds were isolated and identified as isopicrodeoxypodophyllotoxin(I), 3beta-hydroxy-7alpha-methoxy-24beta-ethyl-cholest-5-ene(II), 5alpha, 8alpha-epidioxy-(22E,24R)-erg-osta-6,22-dien-3beta-ol(III), 7beta-hydroxysitosterol (IV), beta-sitosterol (V), daucosterol (VI), alpha-glyceryl palmitate (VII), alpha-D-glucose (VIII), 5-hydromethyl furaldehyde (IX). CONCLUSION: Compounds I - IV, VII - IX are obtained from this genus for the first time.
