Natural antibacterial and antiviral preparation as well as preparation method and application thereof

Abstract

The invention belongs to the technical field of medicines, and discloses a natural antibacterial and antiviral preparation, and a preparation method and application thereof, the preparation method ofthe preparation comprises the following steps: 1) screening grapefruit seeds, crushing the grapefruit seeds to a certain particle size, adopting ethanol as an extracting agent, extracting in a stirring manner to obtain a crude extract, and filtering the crude extract to obtain a filtrate; recovering ethanol to obtain an extracting solution; and 2) adding glycerin into the extracting solution in the step 1), adding water for diluting by a certain multiple to obtain a diluent, and adding citric acid, sodium citrate and a compound biological enzyme into the diluent to obtain a mixed solution. According to the preparation disclosed by the invention, all the components cooperate with one another, firstly, capsules of the preparation are rapidly dissolved, then, cell dissolution is further promoted, pear fire blight germs are effectively inhibited, and meanwhile, the preparation can rapidly take effect on common bacteria and has a broad-spectrum antibacterial effect.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a natural antibacterial and antiviral preparation, a preparation method and an application thereof. Background technique [0002] The amylovora pathogen is a destructive plant pathogenic bacterium with a wide range of hosts, which can harm more than 40 genera and more than 220 kinds of plants such as pears, apples, hawthorns, arborescens, and plums, causing serious economic losses. The main symptoms after infection are: the flower organs are wilted, dark brown, and spread down to the flower stalk, making the flower stalk water-stained. Leaf disease starts to turn black from the edge of the leaf, then develops along the veins, and finally the whole leaf turns black and withers. The diseased fruit is initially water-soaked, and then turns dark brown, with yellow mucus overflowing, and finally the diseased fruit turns black and shrinks. The branches are damaged, initi...

Problems solved by technology

[0009] In view of the methods of preventing and treating pear fire blight in the prior art, chemical agents are usually used, which can easily cause the defects of plant drug resistance, pollute the environment, and destroy the ecological balance. The use of biological bacteria control methods can easily lead to the proliferation of bacteria, which also has the risk of destroying the ecological balance. , the present invention provides a preparation containing pomelo seed extract, citric acid, sodium citrate, glycerin and compound biological enzymes, using the synergy of each component, first rapidly dissolves its capsule, and then further promotes cell lysis, effectively inhibiting pear Fire blight bacteria, no pollution to the environment, conducive to the production of green, pollution-free products
