Strychnine and brucine were extracted from slices of strychni seeds, cut into various sizes (#1-#4), in water at 27,37,and 47°. Results of analysis of extraction rate showed that the mechanism of extraction consists of washing, diffusion, and capillary extraction, but the capillary extraction occupies a small part. Mass transfer coefficients of these three mechanisms, which depend distinctly on temperature of the solvent, were determined.
