Objective: To investigate the chemical constituents of Stephania micrantha. Method: The powered tuber of S.micrantha were extracted with 2% H2SO4-H2O and purified by silica gel
alumina oxide and Sephadex LH-20 column chromatograph.The structures were elucidated on the basis of spectral analysis and physico-chemical evidence. Result: Seven alkaloid compounds were obtained from the tuber of S.micrantha
they are characterized as sinoacutine(1)
sinomenine(2)
cephamonine(3)
tetrahydropalmatine(4)
palmatine(5)
capaurine(6)
and(+)-stepharine(7). Conclusion: Compounds 3
5
7 were isolated for the first time from S.micrantha.
