Abstract:
     The process is that on the basis of chemical compsn. analysis for the mother chrysanthemum, repeated experiment and comparason are carried on for manytimes, and a new counter flow washing-extracting sequence is adopted; i.e. a process of soaking once-washing twice. Owing to the fact that the quantity of solvent is increased, the difference of extracting concn. is sufficiently enlarged and the extraction period is extended appropriately, the yield is increased with a pure oil content of 61.5%, and the prod. quality in accord with the demands.
