LEAF ALKALOIDS OF SOPHORA MACROCARPA

Abstract

The seeds of Sophora mcrcrocarpo Sm. (Fabaceae) are a promising source of edible oil (l), and contain matrine, N-methylcytisine and baptifoline (2). Glc analyses of the leaves of this species suggested that matrine is always, by far, the major alkaloid, accompanied by several unidentified minor bases (3). Fractionation of the crude leaf alkaloids has now sfforded matrine, matrine N-oxide, sophoranol, N-methylcytisine and cytisine.
