Embodiment 1

[0020] 1 kg of Coptis chinensis leaves and or stems are dried and crushed. Add 2 liters of 5% sulfuric acid solution, stir and extract at room temperature for 20 hours. Filter to obtain an extract, and adjust the extract to a pH of 4-7. After the extract is properly concentrated, Tween80 is added as an auxiliary agent. It is antibacterial pesticide synergist. Adding the pesticide synergist in an appropriate amount to pesticides such as streptomycin can increase the antibacterial activity of streptomycin by more than 5 times.

Embodiment 2

[0022] 1 kg of Coptis chinensis leaves and stems are dried and crushed. Add 10 liters of 0.01% hydrochloric acid solution, stir and extract at 90° C. for 3 hours. Filter to obtain an extract, and adjust the extract to a pH of 4-7. After the extract is properly concentrated, Tween60 is added as an auxiliary agent. It is antibacterial pesticide synergist. Adding an appropriate amount of streptomycin and other pesticides to the pesticide synergist can increase the antibacterial activity of streptomycin by more than 5 times.

Embodiment 3

[0024] 1 kg of Coptis chinensis leaves are dried and crushed. Add 5 liters of 0.5% sulfuric acid solution, stir and extract at 60° C. for 8 hours. Filter to obtain an extract, and adjust the extract to a pH of 4-7. After the extract is properly concentrated, Tween20 is added as an auxiliary agent. It is antibacterial pesticide synergist. Adding an appropriate amount of streptomycin and other pesticides to the pesticide synergist can increase the antibacterial activity of streptomycin by more than 5 times.

Abstract

The present invention relates to a coptis pesticide synergist. Its composition includes 1 portion of coptis leaf and/or stem and 2-10 portions of 0.01-5% hydrochloric acid or sulfuric acid solution. It preparation method includes the following steps: pulverizing coptis leaf and/or stem, soaking the pulverized coptis leaf and/or stem in acid solution at 20-100deg.C to make extraction for 3-20hr, separating out solution and properly concentrating, adding adjuvant with stabilizing and dispersing action so as to obtain the invented pesticide synergist for resisting bacteria, resisting virus and resisting insects.

Description

technical field [0001] The invention belongs to the pesticide synergist technology, in particular to a Coptis chinensis pesticide synergist. Background technique [0002] Coptidis is bitter in taste and cold in nature. It has the functions of purging fire, detoxifying, clearing heat and drying dampness. For dysphoria, confusion, upset and insomnia, hot and humid fullness, vomiting, abdominal pain and diarrhea, conjunctival congestion and swelling, sore tongue, eczema, burns, vomiting blood, epistaxis, etc. Coptis chinensis was first recorded in "Shen Nong's Materia Medica", and it was listed as the top grade. All kinds of coptis mainly contain berberine (Berberine), also known as berberine, with a content of 5.20-7.69%. Others still contain Coptise, Worenine, Palmatine and Jatrorrhizine. The contents of these bases are all below 0.5%. Because they have similar structures, they are collectively referred to as Coptis. lotus alkaloids. The alkaloids of Coptis chinensis hav...
