A new lupine alkaloid, (-)-14β-hydroxymatrine (1) was isolaed from the dry roots of Sophora tonkinensis together with 11 known lupine alkaloids. The absolute structure (5S, 6S, 7R, 11R, 14S) of the new base was confirmed by comparison of the natural product with a synthetic sample derived from (+)-matrine.
