An extract of Korean corydalis was processed as shown in Chart 1, and protopine, α-allocryptopine, berberine (chloride and iodide), palmitic acid, and stigmasterol were isolated and identified. Two kinds of phenolic bases (picrate, m. p. 172-173°(decomp.), C₂₆H₂₈O₁₁N₄, and of m. p. 275-277°(decomp.) (in vacuo)), yellow needles, m. p. 290-290.5°, C₂₀H₁₄O₆, and colorless microneedles, m. p. above 300°, assumed to be a glycoside (acetate, m. p. 156-158°), were isolated. A liquid fatty acid was derived to its methyl ester, and the presence of oleic, linoleic, and linolenic acids was confirmed by gas chromatography.
