OBJECTIVE To study the cytisine-type alkaloids of CH2C12 fraction from 95％ EtOH extract of Sophora tonkinensis Gapnep.(Leguminosae).METHODS Various chromatographic techniques were used to separate and purify the constituents.Their structures were elucidated by spectroscopic methods.RESULTS N-hexanoylcytisine (6), a new cytisine-type alkaloid was isolated from the rhizomes of S.tonkinensis, together with 5 known cytisine-type alkaloids, N-methylcytisine (1),N-ethylcytisine (2), N-formylcytisine (3), N-acetylcytisine (4), and N-propionylcytisine (5).
