The invention discloses a process method for alcohol extraction of palmatine. According to the process method, the palmatine extracting rate is increased, the extraction time is shortened, the production efficiency is improved, filtrate is easy to filter, the labor intensity is reduced, the use amount of acid water is reduced, and therefore, the use amount of salting out raw materials and the sewage treatment amount are reduced. According to the technical scheme, the process method comprises the following steps of: extracting common fibraurea stem powder with alcohol, combining filtrate, cooling, and filtering to remove insoluble impurities; drying the filtrate through steaming, and eluting residues after the steaming with acid liquid; filtering eluant, regulating the alkali degree, standing until the insoluble impurities are separated, filtering, adding sodium chloride into the filtrate, carrying out salting out, and filtering to obtain a crude product; and heating to dissolve the crude product into ethanol, immediately filtering to remove the insoluble impurities, after the filtrate is cooled, slowly adding concentrated hydrochloric acid, after palmatine hydrochloride is separated out, filtering, and drying, so as to obtain the product.
