1871 Jrnl. Chem. Soc. 24 1065 Laudanosine..dissolves sparingly in cold, but easily in hot benzol; it forms colourless prisms which melt at 89°.

1900 Chemist & Druggist LVII. 846/1 It is therefore probable that laudanosine is d-N-methyl-tetra-hydro-papaverine.

1910 Practitioner June 879 This product is made by the oxidation of laudanosine.

1951 A. Grollman Pharmacol. & Therapeutics iv. 88 The remaining [opium] alkaloids (laudanosine,..codamine, gnoscopine, etc.) occur in too small quantity to have any influence on the action of the crude drug.

1972 Phytochemistry XI. 461 The major alkaloids of the above-ground parts of Argemone grandiflora..were found to be berberine, α-allocryptopine and protopine; (+)-laudanosine..and chelerythine were identified as minor alkaloids.
