ABSTRACT
OBJECTIVE:
To study the alkaloids in the stems and leaves of Stephania cepharantha Hayata.METHODS:
The dried stems and leaves of Stephania cepharantha Hayata were percolated with 95% ethanol and the solvent was removed by rotary evaporation to give a concentrate, and the concentrate was extracted by petroleum ether and chloroform. Column chromatograghy on MCI CHP 20P, silica gel, Rp-18, Sephadex LH-20 and polyamide were applied for the isolation and purification of the chloroform fraction. The structures were elucidated by their physicochemical properties and spectral data.RESULTS:
Five alkaloids were obtained and identified as, Stephasunoline (I) Aknadinine (II), Discretamine (III), Acutumine (IV), Sinomenine (V).CONCLUSION:
Compounds I, III, IV are isolated from this plant for the first time, and compound IV is isolated from the genus for the first time.
