Abstract

Ten monomeric indole alkaloids have been identified from the roots of Kopsia officinalis. Four of them are known: (-)-kopsinine 1, (+)-5,22-dioxokopsane 2, (-)-tetrahydroalstonine 4, and (-)-quebrachamine 3; and six are new: (-)-isoeburnamine 5 (enantiomer of the known alkaloid (+)-isoeburnamine), (-)-N-methoxycarbonyl-12-methoxykopsinaline 7, (-)-N-methoxycarbonyl-11,12-methylenedioxy kopsinaline 8, (-)-N-methoxycarbonyl-11,12-dimethoxykopsinaline 9, (-)-11,12-methylenedioxykopsinaline 10, and (-)-12-methoxykopsinaline 11.
