Embodiment 1

[0052] A kind of natural plant fungicide, its component comprises neem fruit extract 70wt%, tea seed extract 15wt%, and Sapindus sapindosa sapindosa ethanol extract 15wt%, wherein, neem fruit extract, tea seed extract, and The extraction process of the alcoholic extract of Sapindus saponins is as follows:

[0053] Extract of neem seeds: rough selection of neem seeds, stirring and extruding to remove the core, coarse filtration, and crushing; soaking the crushed neem seeds in an organic ester solvent for 48 hours; ultrasonic beating for 8 hours; standing for stratification, extracting the oil layer; Alkali saponification; filter, take the filtrate, decolorize and deodorize with activated carbon, concentrate to obtain neem extract, the extraction rate can reach 38%;

[0054] Tea seed extract: first prick and remove the shell, screen the tea seeds; squeeze the tea seeds, fine filter, and take the liquid; add alkaline protease, heat and saponify and hydrolyze; after high-speed dis...

Embodiment 2

[0067] The difference between this example and Example 1 is that: the composition of the natural plant fungicide in this example includes 75wt% of neem extract, 10wt% of tea seed extract, and 15wt% of Sapindus sapindosa ethanol extract, Wherein, the mass ratio of processed Sapindus sapindosa and sapindella sapindosa alcohol solution in the extraction process is 75:25.

[0068] The natural plant fungicide provided in this example was sent to the Guangdong Provincial Microbial Analysis and Testing Center for safety identification and bacteriostatic performance identification. The heavy metal content of the natural plant fungicide provided in this example was far lower than the national standard, and the antibacterial effect was good , only a small amount can produce excellent antibacterial effect.

Embodiment 3

[0070] A kind of natural plant fungicide, its composition comprises neem fruit extract 72wt%, tea seed extract 12wt%, and Sapindus sapindus acacia alcohol extract 16wt%, wherein, neem fruit extract, tea seed extract,

[0071] And the extraction process of sapindus sapindosa ethanol extract is as follows:

[0072] Extract of neem seeds: rough selection of neem seeds, stirring and extruding to remove the core, coarse filtration, and crushing; soaking the crushed neem seeds in an organic ester solvent for 24 hours; ultrasonic beating for 8 hours; standing for stratification, extracting the oil layer; Alkali saponification; filter, take the filtrate, decolorize and deodorize with activated carbon, concentrate to obtain neem extract, the extraction rate can reach 34%;

[0073] Tea seed extract: first prick and remove the shell, screen the tea seeds; squeeze the tea seeds, fine filter, and take the liquid; add alkaline protease, heat and saponify and hydrolyze; after high-speed disp...

Abstract

The invention provides a natural plant fungicide and a preparation method of the natural plant fungicide. The natural plant fungicide is prepared by mixing 60-80wt% of chinaberry seed extract, 3-20wt% of tea seed extract and 10-30wt% of soapberry gleditsia sinensis alcohol extract. The preparation method comprises the steps of squeezing the soapberry, and removing stones; soaking the treated soapberry by gleditsia sinensis alcohol liquid; heating and pulping; filtering and taking a filtrate; adding alkaline protease and carrying out hydrolysis; concentrating, filtering and taking the filtrate to obtain the gleditsia sinensis alcohol liquid for the soapberry. According to the natural plant fungicide and the preparation method of the natural plant fungicide, all-natural plant extracts are adopted; due to scientific extraction, the extraction rate is effectively improved; the extracted product is good in water solubility; due to the reasonable compatibility of the multiple different extracts, better sterilization, antibiosis and bacteriostasis synergy effect can be achieved; the natural plant fungicide does not contain chemical additives, thus being non-toxic, harmless and free from side effects to the human body and high in safety, and free from environmental pollution; therefore, the natural plant fungicide is widely applied to the fields such as food, cosmetics, personal cleaning supplies, home cleaning products, daily chemical products, etc.

Description

technical field [0001] The invention relates to a fungicide, in particular to a natural plant fungicide and a preparation method thereof. Background technique [0002] With the development of society and the continuous improvement of people's living standards, food, cosmetics, personal cleaning products, household cleaning products and other daily chemical products are increasingly widely used. The above products have a kind of important additives in their formula composition - preservatives. Preservatives are mainly used in the components to prevent product deterioration and prolong storage time. At present, most of the preservatives used in the industry are compounds, which are more or less harmful to the human body to a certain extent. In addition, the compatibility of preservatives and the pollution to the environment after use have always been a concern of people. [0003] With the development of science and technology, along with people's understanding of natural plan...
