Abstract

The invention discloses a preparation method and application of an open arrow extract. The preparation method of the open arrow extract uses open arrow rhizomes as raw materials, extracts them with ethanol aqueous solution or ethyl acetate as a solvent, concentrates, and dries them. To obtain the open arrow extract, when the solvent is ethanol aqueous solution, the volume fraction of ethanol is not less than 60%. The present invention uses ethanol-water solution or ethyl acetate as a solvent to prepare the open arrow extract, all of which are completed in one step, without repeated extraction with multiple solvents, simple process operation, high extraction rate, low cost, and environmentally friendly; the prepared extract It can effectively inhibit the growth of filamentous fungi, especially the inhibitory effect on Penicillium expansica, Penicillium italicum, Penicillium digitatum, Aspergillus niger, Rhizopus stoloniferus, Botrytis cinerea, etc. / mL) has good effect, broad antibacterial spectrum, no harmful organic solvent residue, environment-friendly, less toxic and side effects on non-targets, and conforms to the sustainable development concept of green environmental protection.

Description

technical field

[0001] The invention relates to a preparation method and application of an open arrow extract, belonging to the field of open arrow extraction. Background technique

[0002] With the improvement of living standards, more and more people begin to pay attention to the safety of preservatives in the storage process of fruits and vegetables and other foods. Tobuzin, etc., as well as sec-butylamine and its derivatives, Xianbao, Baidusha, etc., are mostly chemically synthesized. Overdosage of drugs is common in some areas or crops, posing risks to the quality and safety of agricultural products.

[0003] Although physical fresh-keeping methods such as controlled atmosphere and refrigeration can effectively delay the physiological and biochemical processes of fruits and vegetables after harvest and maintain the freshness of fruits, their disadvantages are that once they leave the original physical environment, especially after mechanical damage, they are easily infe...
