ALKALOIDE DER IN BULGARIEN VERBREITETEN GATTUNG CHAMAECYTISUS

Abstract

From the genus Chamaecytisus (Leguminosae), spread in Bulgaria, nine species have been investigated. Two of them are poor of alkaloids. The other seven could be devided into two groups. The first one with l-sparteine as the main alkaloid, the second one with d-lupanine. In the first group there were also isolated l–17–oxosparteine, d-lupanine and a new alkaloid, designated as C₂ with the formula C₁₂H₂₀O N₂. In the second group of plants there we could isolât besides d-lupanine and l-sparteine another new alkaloid, designated as C₁ with the formula C₁₅H₂₄O₂N₂, probably a hydroxylupanine.
