Manske isolated four kinds of alkaloids, protopine, adlumidine, l-corypalmine, and structurally unknown substance, C19H19O5N, from Corydalis incisa. Extraction of the same plant, collected in Hyogo and Kyoto Prefectures afforded seven kinds of alkaloids as tertiary bases and two these were identified as sanguinarine and protopine. The others are still of unknown structure, C21H21O5N of m.p. 216-217°, C21H21O5N of m.p. 235-236°, C22H23O6N of m.p. 240°, C21H19O5N of m.p. 209°, and C21H21O4N2 forming a methiodide of m.p. 163°.
