<jats:title>Abstract</jats:title> <jats:p>13 Alkaloids were identified in leaves and twigs of Platycelphium vöense (a monotypic genus in the tribe Sophoreae) by capillary GLC and GLC-MS. Cytisine, N-methylcytisine, anagyrine and 5,6-dehydrolupanine figured as major and N-formylcytisine, N-acetylcytisine, baptifoline, thermopsine, isolupanine, and rhombifoline as minor alkaloids in both leaves and twigs. Lupanine occurred in considerable amount in the leaves and as a minor component in the twigs. The rare alkaloid, 6β-hydroxylupanine, was detected only in the leaves while N-ethylcytisine was shown to be a minor constituent of the twigs only.
