Vegetable matter aquatic animal ectoparasite prevention and cure agent and preparation method thereof

Abstract

The invention relates to a plant source of a plant marine product animal external antiparasitic preventing agent and its preparing process, wherein the preparation comprises ginko outer seed coat extract or ethanol as dissolvent, as well as surface active agent, and the preparation process comprises the steps of, disintegrating the ginko outer seed coat, backflow extraction with methanol, concentrating the extract, extracting with waterless industrial alcohol, thus obtaining the concentration extract, mixing surface active agent, ethanol dissolvent, and ginko outer seed coat extract in homogenizer, stirring 30 minutes, cooling down to normal temperature to obtain the preparation.

Description

technical field [0001] The invention relates to biopharmaceuticals, in particular to a raw material of a plant-based aquatic animal ectoparasite control agent suitable for aquaculture and a preparation method thereof. Background technique [0002] The prevention and control of aquatic animal parasites is an important guarantee measure for the economic benefits of aquaculture. Aquatic animal parasitic diseases have a high incidence rate and are widely prevalent. Among them, the most harmful ectoparasites include protozoa such as trichotillomania, small melon worm; Wait. At present, insecticides such as dichlorvos, acephate, malachite green, and mercurous nitrate have been banned in aquatic products due to poor safety, environmental pollution, and potential harm to humans. At present, chemical agents such as mebendazole, praziquantel, betin, abamectin, formalin, trichlorfon, pyrethroids, methylene blue, and potassium permanganate are mostly used to prevent and control aquati...
