COMPREHENSIVE UTILIZATION METHOD FOR CANNA INDICA L. PLANTS

摘要

A comprehensive utilization method for Canna indica L. plants, comprising the following steps: respectively pulverizing root tubers, stems, and leaves of Canna indica L. plants, carrying out esterase conversion or esterase-expressing Escherichia coli whole cell conversion; separating into a solid phase and a liquid phase which are then processed separately; the liquid phase is firstly separated by using a macroporous adsorption resin, and then purified by using preparative chromatography so as to obtain rosmarinic acid, caffeic acid, and tanshinol; solid substances which are obtained from the solid-liquid separation of conversion materials of the stems and leaves are dried to obtain a silage feed, and conversion materials of the roots are separated to obtain starch, while the remaining solid substances are partially dried to obtain a high-fiber feed.
