Two new indole alkaloids, viz. , arboloscine ( 1 ), the first example of a secoleuconoxine, and pericidine ( 5 ), an oxidized derivative of pericine ( 6 ), were obtained as minor alkaloids from the stem‐bark extract of the Malayan Kopsia species, K. arborea. Their structures were established by spectroscopic analysis.
