Problems solved by technology

[0003] At present, the cultivation of tea is mainly in the south of the Yangtze River, which is the main production in my country. During the cultivation process, due to the influence of terrain, climate and soil, various pests will appear, so it is inevitable to spray chemical pesticides to eliminate insects. , which is contrary to the concept of pollution-free planting, and it is easy to leave toxic substances, causing inestimable harm to the body of people who drink tea

Embodiment 1

[0039] Embodiment 1: a kind of eutectic of carvacrol and fumaric acid, its preparation method is: prepare the ethanol solution of carvacrol and the ethanol solution of fumaric acid respectively, add the ethanol solution of fumaric acid under stirring condition into the ethanol solution of carvacrol, stirred and reacted at 50° C. for 4 hours, filtered to collect the solid, and dried.

[0040] The molar ratio of carvacrol and fumaric acid is 1:1.00; in the ethanol solution of carvacrol, the mass ratio of carvacrol and ethanol is 1:1.0; in the ethanol solution of fumaric acid, fumaric acid and ethanol The mass ratio is 1:2.0.

[0041] NMR test verifies that carvacrol and fumaric acid form a co-crystal.

[0042] The purity of the co-crystal of carvacrol and fumaric acid was 99.2% as tested by HPLC.

[0043] X-ray powder diffraction test such as figure 1 shown. The X-ray powder diffraction pattern expressed in 2θ of the cocrystal of carvacrol and fumaric acid has characteristi...

Embodiment 2

[0045] Embodiment 2: a kind of eutectic of carvacrol and fumaric acid, its preparation method is: prepare the ethanol solution of carvacrol and the ethanol solution of fumaric acid respectively, add the ethanol solution of fumaric acid under stirring condition into the ethanol solution of carvacrol, stirred and reacted at 48° C. for 5 hours, filtered to collect the solid, and dried.

[0046] The molar ratio of carvacrol and fumaric acid is 1:0.95; in the ethanol solution of carvacrol, the mass ratio of carvacrol and ethanol is 1:0.8; in the ethanol solution of fumaric acid, fumaric acid and ethanol The mass ratio is 1:1.8.

[0047] The purity of the co-crystal of carvacrol and fumaric acid was 97.8% as tested by HPLC.

[0048] The X-ray powder diffraction test is the same as in Example 1.

Embodiment 3

[0049] Embodiment 3: a kind of eutectic of carvacrol and fumaric acid, its preparation method is: prepare the ethanol solution of carvacrol and the ethanol solution of fumaric acid respectively, add the ethanol solution of fumaric acid under stirring condition into the ethanol solution of carvacrol, stirred and reacted at 52°C for 3 hours, filtered to collect the solid, and dried.

[0050] The molar ratio of carvacrol and fumaric acid is 1:1.05; in the ethanol solution of carvacrol, the mass ratio of carvacrol and ethanol is 1:1.2; in the ethanol solution of fumaric acid, fumaric acid and ethanol The mass ratio is 1:2.5.

[0051] The purity of the co-crystal of carvacrol and fumaric acid was 98.1% as tested by HPLC.

[0052] The X-ray powder diffraction test is the same as in Example 1.

Abstract

The invention discloses a camellia sinensis pest repellant from plant-source extract products. The camellia sinensis pest repellant comprises (by molar mass): 1 part of carvacrol, 0.90-1.10 parts of capsaicin, 0.45-0.55 part of gastrodin and 0.30-0.37 part of naringenin. The camellia sinensis pest repellant is good for plant-source pest repelling, is efficient, low-toxic and easily-degraded, and causes no residue or drug resistance.

Description

technical field [0001] The invention relates to a tea tree insect repellent of plant source extract. Background technique [0002] Tea originated in my country and is one of the most commonly consumed beverages in the world. Its consumption is second only to water and higher than coffee, beer, wine and carbonated drinks. Generally speaking, tea contains tea polyphenols, tea polysaccharides, caffeine, proteins, amino acids, vitamins, minerals and other nutritional and pharmacological components, which are the material basis for the biological activity of tea. substances, vitamins, amino acids and other nutrients, and can take in antioxidant active substances such as tea polyphenols, which have a comprehensive physiological regulation effect on the body. [0003] At present, the cultivation of tea is mainly in the south of the Yangtze River, which is the main production in my country. During the cultivation process, due to the influence of terrain, climate and soil, various p...
