THE ALKALOIDS OF FUMARIACEOUS PLANTS: XXIV. <i>CORYDALIS OCHOTENSIS</i> TURCZ.

Abstract

The alkaloids of Corydalis ochotensis consist of four known bases, namely, protopine, cryptocavine, ochotensine, and aurotensine, together with two new ones, namely, ochotensimine (F48) and alkaloid F49. Ochotensimine is the O-methyl ether of ochotensine. It has not been obtained crystalline, but it has been characterized as the methiodide and the derived dihydro-methine base. In addition to acetyl-ornithine, the isolation of which has already been recorded, fumaric acid and maltol were also found.
